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.
