SLC™ 500 4-Channel Thermocouple/mV Input Module 11
Publication 1746-IN010D-EN-P - June 2004
Terminal Wiring
The thermocouple module contains a green, 18-position, removable terminal block.
The terminal pin-out is shown below.
Terminal screws accept a maximum of two #14 AWG (2 mm
2
) wires. Tighten
terminal screws only tight enough to immobilize wires. Maximum torque on
terminal screws is 0.7 to 0.9 Nm (6 to 8 in-lbs).
ATTENTION
Disconnect power to the SLC before attempting to install,
remove, or wire the removable terminal wiring block.

(1) Replacing a Series A thermocouple module with a Series B module requires that the bottom right terminal (which was
SHIELD on Series A modules) no longer be connected to CHASSIS GROUND if it was previously. Use one of the other
SHIELD terminals.
