GE IC660BLM506 | Genius I/O 150 Ohm Bus Terminator

Product Overview

The GE IC660BLM506 is a bus terminating resistor. This IC660BLM506 plug is critical for Genius I/O bus signal integrity.

Technical Specifications

• Model: GE IC660BLM506
• Function: Bus Terminating Resistor Plug
• Resistance: 150 Ohms
• Weight: 2 Pounds (0.91 kg)
• Connection Pins: 4 pins
• Color: Black
• Installation Tool: Flat screwdriver

Installation & Compatibility

• Location: Must be installed at the first and last node of the Genius I/O bus.
• Terminals: Connected across Serial 1 and Serial 2 terminals.
• Purpose: Prevents signal reflection on the bus, ensuring reliable communication.
• Compatible With: Genius I/O Blocks, Bus Switching Modules (BSM), Bus Controllers, PCIM.
• Cable Compatibility: Works with prefabricated cables (e.g., IC660BLC001, IC660BLC003) and conventional bus cables.

Application Notes

• Redundant Bus: If the last node is a BSM in a redundant system, install the terminator only on the BSM.
• Controller Node: If a Bus Controller is the last node, use this external terminator instead of enabling onboard resistors.
• Advantage: Allows board replacement without breaking bus termination, maintaining system continuity.

FAQ

• Why is bus termination necessary?
• It absorbs the signal at the end of the cable, preventing reflections that cause data errors.
• Where exactly do I install it?
• At the very first and the very last device on the Genius I/O communication bus loop.
• What happens if I don't use it?
• The Genius network may experience intermittent communication faults, noise, or complete failure.
