NARI Relays OUT2 Output Card

Product Details

OUT2 Product Description

The NARI-RELAYS OUT2 is a precision-engineered energy-control output card designed for relay protection systems in modern smart production environments. As industrial facilities push toward leaner energy consumption and higher equipment utilization, the OUT2 delivers reliable, low-latency output switching that directly supports load management, motor control sequencing, and drive coordination across the production line. Built to NARI Relays' stringent quality standards, the OUT2 ships fully tested, carries a 12-month warranty, and is maintained in ready stock to support fast deployment and minimal downtime.

In relay protection architectures, the output card is the final execution layer — the component that translates protective logic decisions into physical switching actions. The OUT2 fulfils this role with high contact reliability, low thermal dissipation, and compatibility with a broad range of industrial control platforms. Whether integrated into a new smart factory build or retrofitted into an existing relay protection panel, the OUT2 reduces unnecessary switching losses and contributes measurably to overall system energy efficiency.

The OUT2 output card does not operate in isolation — its energy-control value is realised through tight integration with the broader automation ecosystem on the production floor. In a typical smart factory deployment, the OUT2 interfaces directly with a PLC (such as a NARI or third-party IEC 61131-3 compliant controller) to receive trip and close commands generated by protective relay logic. These commands are executed with microsecond-level precision, ensuring that motor starters, contactors, and drive enable circuits respond immediately to load conditions without unnecessary hold-on energy.

When paired with a variable frequency drive (VFD) or servo drive system, the OUT2 acts as the hardwired interlock layer that governs drive enable and fault-reset sequences. This prevents drives from restarting under fault conditions — a common source of wasted energy and thermal stress. In servo-driven production lines, coordinating the OUT2 output with servo drive enable signals ensures that axes are only energised when the motion profile demands it, directly reducing idle power draw across multi-axis systems.

Power monitoring modules — such as NARI's own power measurement units or third-party DIN-rail energy meters — feed real-time load data into the SCADA system. The OUT2 acts on the switching decisions that SCADA generates in response to these measurements, enabling dynamic load shedding when consumption thresholds are exceeded. This closed-loop interaction between the power monitoring module, SCADA, PLC, and OUT2 forms the backbone of an effective energy management strategy.

On the I/O layer, the OUT2 complements digital input cards and analogue I/O modules by providing the output switching capacity that input-only modules cannot supply. In relay protection panels, it works alongside current transformer (CT) input cards and voltage measurement modules to form a complete protection and control assembly. HMI terminals connected to the same control network display the switching status of each OUT2 channel, giving operators real-time visibility into which loads are energised, which are shed, and which are in fault state — all critical data for minimising unplanned energy consumption.

Communication modules supporting IEC 61850 GOOSE messaging or MODBUS RTU allow the OUT2's switching status to be reported upstream to the energy management system (EMS) or plant-level SCADA. This telemetry enables predictive maintenance scheduling: by tracking switching frequency and contact wear over time, maintenance teams can plan replacements before contact degradation causes nuisance trips or increased contact resistance — both of which elevate energy losses. Sensor inputs from temperature and vibration transducers mounted on protected equipment further enrich this dataset, enabling condition-based maintenance rather than time-based replacement cycles.

In high-throughput production environments, energy waste most commonly originates from three sources: unnecessary equipment energisation during idle periods, unplanned downtime that forces restart cycles, and thermal losses from overloaded or poorly coordinated switching devices. The NARI-RELAYS OUT2 addresses all three directly.

By providing reliable, low-resistance output switching, the OUT2 ensures that protective relay logic can execute load-shedding commands without hesitation. During scheduled production pauses or shift changeovers, the OUT2 enables controlled de-energisation of non-critical loads — conveyors, auxiliary pumps, lighting circuits — reducing the facility's base load during low-production windows. When production resumes, the same output channels execute a sequenced re-energisation that prevents inrush current spikes from stressing the supply infrastructure or tripping upstream protection devices.

Unplanned downtime is one of the most energy-intensive events in a production facility, because restart cycles consume disproportionately high energy compared to steady-state operation. The OUT2's high contact reliability and tested switching performance reduce the probability of nuisance trips caused by contact bounce or degraded output performance. Each unit undergoes factory testing prior to shipment, and the 12-month warranty provides assurance that field performance will match specification throughout the initial deployment period.

Thermal load management is another area where the OUT2 contributes to production line efficiency. Low contact resistance means less heat generated per switching cycle, reducing the thermal burden on the relay protection panel and the cooling systems that serve it. In densely populated control cabinets, this thermal saving translates directly into reduced air-conditioning load — a meaningful contribution to the facility's overall energy balance. Combined with proper panel layout and ventilation design, the OUT2 helps maintain stable operating temperatures that extend the service life of adjacent components, including communication modules, power supplies, and I/O cards.

For production lines targeting ISO 50001 energy management certification or internal carbon reduction targets, the OUT2 provides the switching precision needed to implement granular load control strategies. Its compatibility with IEC 61850-compliant protection systems means that energy data collected at the field level can be aggregated, analysed, and acted upon at the enterprise level — closing the loop between energy measurement, protective action, and continuous improvement.

Q1: How does the OUT2 contribute to measurable energy savings on the production line?The OUT2 enables precise, low-loss output switching that supports load-shedding logic, controlled de-energisation during idle periods, and sequenced restart strategies. By minimising contact resistance and switching losses, it reduces thermal dissipation within the control panel and supports the broader energy management strategy coordinated through SCADA and the plant EMS. Facilities using structured load control via relay protection output cards typically report measurable reductions in auxiliary system energy consumption.

Q2: Which control systems and communication protocols is the OUT2 compatible with?The OUT2 is compatible with PLC-based control architectures, DCS platforms, and relay protection panels operating under IEC 61850, MODBUS RTU, and hardwired I/O schemes. It integrates with SCADA systems for remote switching status monitoring and supports HMI visualisation of output channel states. For IEC 61850 deployments, GOOSE messaging can be used to coordinate switching actions across multiple intelligent electronic devices (IEDs) on the same protection network.

Q3: Can the OUT2 replace existing output cards from other relay protection manufacturers?The OUT2 is designed for use within NARI Relays relay protection systems and should be evaluated against the specific output card slot requirements of the target protection relay or panel. Before substitution, verify contact rating, output channel count, connector pinout, and firmware compatibility with the host relay. NARI Relays technical documentation and application engineers can confirm compatibility for specific replacement scenarios. All units are shipped tested and include a 12-month warranty covering manufacturing defects.

Q4: What is the lead time and warranty coverage for the OUT2?The NARI-RELAYS OUT2 is maintained in ready stock and is available for immediate dispatch. Standard lead time for in-stock units is subject to order confirmation and logistics arrangement. Each unit is covered by a 12-month warranty from the date of shipment, covering manufacturing defects and performance deviations from published specifications. Pre-shipment testing is conducted on every unit to verify output contact performance, insulation integrity, and operational reliability before dispatch.
