Which connectors does it support?
It mates with 25‑pin expansion cable connectors like IC693CBL302 and IC693CBL314.
Does it contain active electronics?
No — it’s a passive terminator with resistor network for bus line termination.
What environments can it operate in?
Industrial temperature range up to 55 °C and storage down to –40 °C.
Is this part still made by GE?
It’s a legacy/discontinued part but widely available from surplus sellers.
Why is proper termination important?
Terminators prevent signal reflection and noise that can disrupt communication on long bus runs.
How heavy is the module?
Approximately 0.09 kg (90 g / 0.19 lbs).
Can it install without tools?
Yes — it plugs directly into the designated backplane connector.
Does it support modern PLC systems?
It’s specific to GE Series 90‑30 and similar backplane architectures; not typically used with modern distributed networks.
What is the role of the resistor pack?
The resistive termination matches characteristic cable impedance, reducing reflection and improving signal quality.
