5.4.2 TBCI 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.
