Control Output Wiring

The following figures show the proper control output wiring for the various CN 2110 configurations.

R1 (1 Amp Relay) and T1 (1 Amp, Solid State Relay) Output Wiring

When driving a contactor coil or other inductive load, an appropriately rated AC snubber circuit is recommended (Omega Part. No. CNQUENCHARC), as shown in Figure 3.9.
