20 Configuring the Relay Multiplexer Modules Chapter 2
Connecting Field Wiring
Figure 2-1 shows the terminal module for the 16-Channel High Voltage
Relay (E1343A), 16-Channel Relay (E1345A), 16-Channel General
Purpose Thermocouple High Voltage Relay (E1344A), and 16-Channel
Thermocouple Relay Multiplexer Modules (E1347A). Use the following
guidelines for wire connections.
Wiring Guidelines If possible, use shielded cables with the shields connected to the Guard
(G) terminals and to the low connection near the measurement point.
Be sure the wires make good connections on the screw terminals.
For thermocouples, connect the Guard terminal to the thermocouple's
shield lead and the low connection near the measurement point.
