GE IC693ACC307A Bus Terminator | 110 Ohm, 10-Pin, 25g

Core Function of This Bus Terminator Plug

The GE IC693ACC307A terminates the end of an I/O bus segment. This terminator plug prevents signal reflections that cause communication errors. It provides the correct impedance matching for the expansion cable network. Consequently, the device ensures reliable data transmission between PLC racks.

Physical Dimensions and Component Layout

This bus terminator plug measures 45 mm in total length. Its width reaches 30 mm for a compact accessory form factor. The component thickness stands at 15 mm including the connector body. You will find 6 discrete components inside the molded housing. These include one resistor network and five passive components. The GE IC693ACC307A weighs approximately 25 grams for lightweight attachment.

Electrical Specifications and Termination Method

The GE IC693ACC307A provides a 110-ohm termination impedance across the bus pair. This matches the characteristic impedance of the I/O bus cable. The terminator connects between the A and B signal lines of the bus. It also includes a pull-up resistor to 5 V on the A line. A pull-down resistor to ground connects to the B line. This biasing ensures proper logic levels on unterminated networks.

Connector Type and Installation Method

This terminator plug uses a 10-pin rectangular connector housing. The connector mates directly with the I/O bus expansion port. A locking latch secures the plug to prevent accidental removal. The molded housing features a polarized key for correct orientation. Users can install or remove the plug without any tools.

Bus Compatibility and Network Placement

The GE IC693ACC307A works exclusively with Series 90-30 I/O bus networks. You must install this terminator on the last device of each bus segment. The first device in the segment does not require a terminator. A single system can use up to four terminators on separate segments. The module does not function as a repeater or signal booster.

Signal Integrity and Performance Benefits

This terminator plug eliminates standing waves on long bus cables. It reduces bit errors caused by impedance mismatches. The device also improves noise immunity from nearby power wiring. Proper termination allows maximum cable length of 200 meters. Without this terminator, communication errors may occur intermittently.

Environmental Ratings and Durability

The GE IC693ACC307A operates reliably from 0°C to +60°C ambient. The molded housing meets UL 94 V-0 flammability requirements. The connector withstands 500 mating cycles without performance degradation. The device contains no batteries or energy storage components. The terminator requires no maintenance or periodic replacement.

Installation and Placement Notes

You must install this terminator on the last expansion rack of each bus. Always push the plug until the locking latch clicks securely. Then, verify that no other terminator exists on the same segment. The system will not operate correctly with missing or extra terminators. Store spare terminators in a clean, dry location to protect the connector pins.
