Digital Output Module | GE IC600YB908B

The General Electric IC600YB908B is a 16-channel transistor sourcing output module designed for the Series Six PLC platform. Operating at 24 VDC nominal, this solid-state module drives actuators, relays, solenoids, and indicator lights across industrial control applications. It mounts directly into any standard Series Six rack slot and incorporates built-in short-circuit and overload protection to prevent fault propagation to internal controller circuitry.

Channel Specifications and Output Performance

The module provides 16 independent PNP sourcing outputs capable of switching up to 0.5 A per channel, with an overall module output limit of 8 A across all channels. Featuring rapid response times of typically 0.5 ms, each channel maintains an ON-state voltage drop under 1.5 V at full 0.5 A load and restricts OFF-state leakage current below 0.1 mA. Front-panel LEDs provide immediate visual status for each output channel.

Electrical Protection and Wiring Installation

Field wiring attaches via a removable screw-clamp terminal block accepting wire gauges from 0.5 to 1.5 mm2. The module draws 200 mA from the 5 VDC backplane logic bus and relies on an external 24 VDC supply connected to a common return terminal to power connected loads. Thermal protection automatically shuts down outputs during excessive current draw, recovering once normal operating temperatures resume.

Frequently Asked Questions

Q: Does the GE IC600YB908B provide power to field devices directly from the PLC backplane? A: No, the 5 VDC backplane bus only powers the internal logic circuitry. Field loads require an external 10-30 VDC power supply connected to the terminal block.

Q: How does the IC600YB908B recover when a thermal overload occurs on an output channel? A: The module features automatic thermal shutdown, which temporarily disables the affected output during excessive current draw and automatically resets operation once internal temperatures return to safe operating limits.
