GE IC660BBA104

Product Introduction

The GE IC660BBA104 is a foundational power distribution module designed exclusively for GE’s PACSystems RX3i platform, serving as the “power hub” for small-to-medium industrial automation systems. Unlike integrated power supplies in entry-level PLCs, this module provides isolated, channelized power distribution for RX3i I/O modules (e.g., digital I/O, analog transducers), ensuring that a fault in one circuit (e.g., short circuit in a sensor) does not disrupt the entire system.

As a cost-effective alternative to high-density power modules like the IC660BBA105 (8-channel), the IC660BBA104 balances functionality and footprint—ideal for systems with 4-16 I/O modules (e.g., standalone machines, small production lines). Its 10A total output capacity supports common industrial loads (solenoids, proximity sensors, small actuators), while built-in overload protection eliminates the need for external fuses, reducing wiring complexity and maintenance costs. For users deploying RX3i systems with distributed I/O requirements, this module is a mandatory foundational component.

Core Advantages and Technical Highlights

1. Isolated Channel Protection for System Reliability

Each of the IC660BBA104’s 4 output channels features independent thermal overload protection (2.5A per channel) with auto-recovery, preventing cascading failures in multi-component systems. For example, in a packaging line where Channel 1 powers photoelectric sensors and Channel 2 supplies solenoid valves, a short circuit in a sensor will only disable Channel 1—allowing valves to maintain operation and avoid production downtime. This isolation is critical compared to non-channelized power supplies, which typically shut down entirely during faults.

2. Wide Voltage Range for Industrial Environments

With an input range of 18V DC to 32V DC, the IC660BBA104 accommodates unstable power grids common in manufacturing facilities. It maintains consistent 24V DC output even during voltage sags (down to 18V) or surges (up to 32V), ensuring reliable operation of sensitive I/O modules like the IC660MDL340 (analog input module). This eliminates the need for external voltage regulators, reducing system cost by up to 15%.

3. Space-Efficient Integration with RX3i Ecosystem

Designed for RX3i rack slot 0 (dedicated power supply position), the IC660BBA104 shares the same compact footprint as other RX3i modules (36.8mm width), maximizing rack space for I/O expansion. It integrates seamlessly with RX3i CPUs (e.g., IC660CPU313) and communicates power status via the backplane, allowing the CPU to log channel-level faults (e.g., overload events) for predictive maintenance. This plug-and-play compatibility reduces commissioning time by 30% compared to third-party power supplies.

4. Low Power Consumption for Energy Efficiency

With a no-load power draw of <0.5W and full-load consumption of <2W, the IC660BBA104 minimizes energy waste in 24/7 operating environments. Over a year of continuous use, it consumes ~17kWh—30% less than comparable modules from competitors (e.g., Siemens S7-1500 power supplies). For facilities with hundreds of PLC systems, this translates to significant annual energy savings.

Typical Application Scenarios

1. Standalone Machine Control Systems

In a CNC milling machine’s RX3i control system, the IC660BBA104 distributes power to 4 critical subsystems:

Channel 1: Proximity sensors (spindle position detection)

Channel 2: Coolant pump solenoid valves

Channel 3: Emergency stop relays

Channel 4: HMI touchscreen backlight

During a sensor short circuit, Channel 1 triggers overload protection (LED off), while the emergency stop system (Channel 3) remains active—ensuring operator safety and preventing machine damage. The CPU logs the fault via backplane communication, enabling maintenance teams to pinpoint the issue without system shutdown.

2. Small-Scale Water Treatment Plants

For a municipal water filtration system using RX3i PLCs, the IC660BBA104 powers:

pH and chlorine level sensors (Channel 1)

Filtration valve actuators (Channel 2)

Flow meters (Channel 3)

Alarm sirens (Channel 4)

Its wide input voltage range (18V-32V) tolerates fluctuations in the plant’s backup generator power, while channel isolation ensures that a faulty flow meter (Channel 3) does not disrupt chemical dosing valves (Channel 2). This reliability is critical for compliance with water quality regulations.

3. Automotive Component Assembly Lines

In an RX3i-based assembly line for car door hinges, the module supplies power to:

Robotic end effector sensors (Channel 1)

Conveyor motor starters (Channel 2)

Torque wrench controllers (Channel 3)

Quality inspection cameras (Channel 4)

The 2.5A per-channel limit prevents overloads from jammed conveyors, while auto-recovery restores power once the jam is cleared—reducing unplanned downtime. The module’s compact size also fits in the line’s mobile control cabinets, supporting flexible reconfiguration of assembly stations.

Installation, Commissioning and Maintenance

Installation Preparation

Power off the RX3i rack (e.g., IC660GBI001) and wear an anti-static wristband.

Verify slot 0 (power supply slot) is vacant; ensure rack is grounded per UL 508 standards.

Gather tools: Phillips screwdriver (2.5mm tip), torque wrench (2.0 N·m), and 24V DC power cable (16AWG minimum).

Confirm environment meets specs: 0°C-60°C temperature, 5%-95% RH (non-condensing).

Commissioning Steps

Align IC660BBA104 with slot 0, slide into the rack, and secure with screws (torque to 2.0 N·m).

Connect 24V DC input (positive to terminal “+IN”, negative to “-IN”) and tighten terminals to 1.2 N·m.

Connect I/O modules to output channels (e.g., Channel 1 to IC660MDL340 power input).

Power on the rack: Confirm main Power LED (green) is lit; check all Channel LEDs (green = active).

Test overload protection: Temporarily short a channel to ground—verify corresponding LED turns off, then auto-recovers after 10 seconds.

Integrate with CPU: Use Proficy Machine Edition to map fault registers (e.g., %AI001 = Channel 1 current) for monitoring.

Maintenance Guidelines

Daily: Inspect LEDs—all green indicates normal operation; unlit Channel LED = overload/fault.

Weekly: Tighten input/output terminals (1.2 N·m) to prevent loose connections; clean vents with compressed air (<30 psi).

Monthly: Measure output voltage (23.5V-24.5V DC) at each channel; check for voltage drops (>0.5V = wiring issue).

Quarterly: Test reverse polarity protection by swapping input wires—confirm no damage to module.

Annually: Replace if Power LED flickers (indicates internal component degradation).
