GE IC660TBD025

Overview

The IC660TBD025 is a Bus Driver (Terminator Base) module from the GE Fanuc Series 90-70 PLC system. It is a crucial component for the Genius I/O Bus network.

• Key Purpose: It converts the controller’s internal signals to the differential serial signals used on the robust, noise-immune Genius bus.
• Physical Role: It mounts on a standard DIN rail and provides two screw-terminal connectors for the bus cabling and a 10-pin connector for interfacing with the bus controller module (IC670GBI001) via a ribbon cable.

Technical Specifications

Parameter Category	Specification
Manufacturer	GE Fanuc / GE Intelligent Platforms (now part of Emerson Automation)
Series	Series 90-70 Genius I/O System
Part Number	IC660TBD025
Description	Bus Driver (Terminator Base) for Genius Bus
Compatibility	Interfaces with the IC670GBI001 Genius Bus Controller module.
Bus Protocol	GE Genius® I/O Bus
Data Rate	153.6 kbaud (Kilobaud)
Number of Drops	Supports up to 32 devices (including the Bus Controller itself) on a single bus segment.
Bus Length	Maximum 7500 ft (2286 meters) with standard Belden 9463 cable (or equivalent twisted pair). The maximum length can be affected by the number of drops.
Termination	The module itself provides the required termination for the bus network. Termination is critical for preventing signal reflections.
Connectors	• Two (2) 6-position screw terminal blocks for the Genius bus IN and OUT. • One (10-pin) female ribbon cable connector for connection to the IC670GBI001 controller.
Isolation	500V AC between the bus and the logic (controller) side.
Power Requirements	+5V DC (sourced from the bus controller module via the ribbon cable).
LED Indicators	Two LEDs on the front panel: • PWR (Green): Indicates +5V power is present. • ACT (Green): Blinks to indicate data activity on the bus.
Operating Temperature	0° to 60° C (32° to 140° F)
Storage Temperature	-40° to 85° C (-40° to 185° F)
Relative Humidity	5% to 95% (non-condensing)
Mounting	Standard 35 mm DIN rail.

Key Features and Functions

1. Signal Conversion: Translates logic-level signals from the bus controller to the differential Manchester II encoded signals used on the Genius twisted-pair bus.
2. Bus Termination: Contains the necessary terminating resistors, making external terminators unnecessary. This is why it’s called a “Terminator Base.”
3. Isolation: Provides 500V of isolation, protecting the sensitive PLC controller from electrical noise, spikes, or ground loops on the field bus.
4. Diagnostics: The PWR and ACT LEDs provide basic status for quick troubleshooting (power presence and communication activity).
