The AO2DO relay module converts the analog outputs of the T3 controller series into a binary dry contact output. The relay contacts support pilot duty only and operate at a maximum of 0.5A/125VAC. The module comes in 3 gang format and mate up directly on the T3 controller terminals, converting 3 AO’s into 3 dry contacts.
Just place the relay module on the AO terminals and tighten the T3 screws—no wiring or jumpers needed.
You can gang the 3-relay module into longer strips to match your application’s IO with the T3 controller’s IO.
