GE IS200TBCIS2C Contact Input With Group Isolation Terminal Board

GE IS200TBCIS2C Contact Input With Group Isolation Terminal Board

Functional Description

The IS200TBCIS2C Contact Input with Group Isolation (TBCI) terminal board accepts 24 dry contact inputs

wired to two barrier-type terminal blocks. For contact excitation, dc power is wired to TBCI. The contact

inputs have noise suppression circuitry to protect against surge and high-frequency noise.

Installation

Connect the wires for the 24 dry contact inputs directly to two I/O terminal blocks on the terminal board.

These blocks are held down with two screws and can be unplugged from the board for maintenance. Each

block has 24 terminals accepting up to #12 AWG wires. A shield terminal strip attached to chassis ground is

located immediately to the left of each terminal block.

In a Simplex system, connect the I/O pack into the TBCI connector JR1. In a Dual system, plug the I/O packs

into JR1 and JS1. In a TMR system, plug the I/O packs into JR1, JS1, and JT1. The I/O pack(s) attach to side-

mounting brackets. One or two Ethernet cables plug into the I/O packs. Connect TBCI to the contact

excitation voltage source using plugs JE1 and JE2.
