Control Output Wiring
The following figures show the proper control output
wiring for the various 2110 configurations.
R1 (1 Amp Relay) and S0 (1 Amp, Solid State Relay)
Output Wiring
When driving a contactor coil or other inductive load,
an appropriately rated AC snubber circuit is recom-
mended (Chromalox Part. No. 0149-01305), as shown
in Figure 3.9.
