AO2DO Analog to Relay Output Converter
The AO2DO module converts T3 controller analog outputs into reliable dry contact relay signals. With a simple snap-on design, it delivers quick, wiring-free installation and dependable performance for automation needs.
Product Highlights:
- Converts an AO to DO dry contact relay output
- 3 relays per module.
- Plugs right into the T3 controller series.
- Use this when you need more relay outputs and have some spare analog outputs.
Description
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.
