Warnings:
• When a relay output is used to drive an inductive
load, it is suggested that you connect an external
snubber network (RC) across the terminals in
accordance with the following table (or use
Chromalox snubber P/N 0149-01305):
• Do not run sensor input wires together with power
cables.
• For thermocouple (TC) wiring, use matching
thermocouple extension wire (i.e. for J T/C, use type
“J” thermocouple extension wire).
• When using shielded sensor cable, ground the shield
at one end only.
