OPTO 22 - GRV-OAC-12 _ AC digital output, 12 channels, 12-250 VAC

Quick Specs:

AC digital output
12 channels
12-250 VAC

The GRV-OAC-12 digital output module can switch up to 12 separate AC loads of 12-250 VAC each. The module is part of the groov EPIC^® system and provides 300 volts of transient protection for sensitive control electronics from industrial field signals. AC outputs are zero voltage turn on and zero current turn off to minimize transients during switching.

The GRV-OAC-12 offers a full set of features, including:

On/off state
Output pulsing/TPO
On/off totalization
Open circuit indication

The GRV-OAC-12 module mounts on a groov EPIC chassis with other discrete, analog, and serial groov I/O modules and a GRV-EPIC-PR1 processor.

NOTE: For projects with simple requirements, the lower-cost GRV-OACS-12 offers on and off switching only.
