Product Details

IC660BBR100 Product Description

The GE IC660BBR100 is a relay output module engineered for the GE Series 90 programmable automation controller platform, delivering reliable discrete output switching for energy-intensive industrial environments. Designed to interface directly with GE Series 90 PLCs — including the IC693CPU374 and IC693CPU364 central processing units — the IC660BBR100 provides robust relay contact outputs capable of driving motors, solenoids, contactors, and other inductive loads with precision timing and minimal switching losses. In smart production lines where every watt counts, this module plays a central role in reducing unnecessary energy consumption by enabling deterministic load control at the field level.

In a fully integrated GE Series 90 automation architecture, the IC660BBR100 relay output module operates as the final control element in a layered energy management strategy. The module receives switching commands from the Series 90 PLC CPU — such as the IC693CPU374 — which executes ladder logic programs that govern load sequencing, motor start/stop cycles, and energy-saving idle routines. When paired with the IC693MDL940 discrete output module and IC693ALG392 analog input module, the IC660BBR100 enables closed-loop feedback between field sensors and the controller, allowing the system to modulate output states based on real-time process conditions rather than fixed timers.

For variable-speed drive applications, the IC660BBR100 works in coordination with GE AF-600 FP series variable frequency drives (VFDs) to manage motor enable/disable signals, ensuring that drives are only energized when production demand requires it. This eliminates the common energy waste associated with motors running at full speed during low-throughput periods. The module's relay contacts are well-suited for interfacing with the control circuits of medium-voltage motor starters and soft starters, providing galvanic isolation between the PLC logic voltage and the motor control circuit.

Power monitoring is handled upstream by the GE Multilin 350 feeder protection relay and IC693PWR321 power supply module, which together provide real-time visibility into bus voltage stability and load current draw. The IC660BBR100 responds to commands derived from this power data, enabling the PLC to shed non-critical loads during peak demand windows — a key strategy for facilities operating under demand-charge tariffs. Integration with GE iFIX SCADA software allows operators to visualize relay output states, log switching events, and generate energy consumption reports across the production floor.

On the communications side, the IC660BBR100 connects through the GE Genius Bus interface, allowing it to exchange I/O data with IC660BBA020 analog input blocks and IC660BBD020 discrete input blocks distributed across the production line. This distributed I/O topology reduces wiring complexity and signal propagation delays, contributing to tighter control loop timing and more responsive load management. HMI visualization is provided by GE Proficy HMI/SCADA Cimplicity panels, giving line operators immediate feedback on output states and energy-related alarms.

The IC660BBR100 contributes to factory energy optimization through several complementary mechanisms. First, its deterministic relay switching — governed by the Series 90 PLC scan cycle — eliminates the random switching delays that can cause inrush current spikes when multiple loads are energized simultaneously. By staggering motor start sequences through PLC logic, facilities can significantly reduce peak demand charges without sacrificing throughput.

Second, the module supports load shedding strategies during scheduled maintenance windows or low-production shifts. When the PLC detects that a production zone is idle — based on inputs from proximity sensors, photoelectric sensors, or flow transmitters connected via IC693MDL645 discrete input modules — it can command the IC660BBR100 to de-energize non-essential loads such as conveyor drives, cooling fans, and auxiliary lighting circuits. This automated load management can reduce energy consumption in idle zones by 15–30% compared to manual shutdown procedures.

Third, the relay output module's compatibility with predictive maintenance workflows enhances overall equipment effectiveness (OEE). By logging relay switching frequency and correlating it with vibration data from field-mounted sensors, maintenance teams can identify abnormal cycling patterns that indicate mechanical wear in actuators or contactors before a failure occurs. This reduces unplanned downtime — one of the largest hidden energy costs in manufacturing, as restart sequences and scrap production consume disproportionate energy relative to steady-state operation.

The IC660BBR100 is supplied from verified inventory, undergoes outgoing functional testing prior to shipment, and is backed by a 12-Month Warranty covering manufacturing defects and operational failures under normal industrial use conditions. Lead times are confirmed at the time of order, and expedited shipping options are available for urgent production line requirements.

Q1: How does the IC660BBR100 contribute to measurable energy savings on a production line? The IC660BBR100 enables the GE Series 90 PLC to implement load sequencing, idle-state de-energization, and demand-response load shedding. When integrated with power monitoring modules such as the IC693PWR321 and upstream feeder protection relays, the system can automatically reduce active load during low-demand periods, cutting unnecessary energy draw from motors, conveyors, and auxiliary equipment without manual operator intervention.

Q2: Is the IC660BBR100 compatible with existing GE Series 90 racks and backplanes? Yes. The IC660BBR100 is designed for direct installation into GE Series 90 I/O racks and is compatible with standard Series 90 backplanes. It communicates via the Genius Bus interface and is recognized by Series 90 CPUs including the IC693CPU374, IC693CPU364, and IC693CPU350 without requiring additional configuration adapters.

Q3: What is the recommended replacement or upgrade path if the IC660BBR100 is discontinued or unavailable? For applications requiring higher output density or solid-state switching, the IC693MDL940 relay output module or IC693MDL930 transistor output module within the Series 90 family are functionally compatible alternatives. For new installations, GE's RX3i platform with the IC694MDL940 offers backward-compatible I/O mapping with enhanced diagnostics and energy reporting capabilities.

Q4: What does the 12-Month Warranty cover, and what is the testing process before shipment? The 12-Month Warranty covers all manufacturing defects and operational failures arising under normal industrial operating conditions from the date of shipment. Prior to dispatch, each IC660BBR100 unit undergoes functional output verification testing to confirm relay contact continuity, coil actuation response, and backplane communication integrity. Warranty claims are processed with a target replacement or repair turnaround aligned to minimize production line downtime.
