- 5 A
The GRV-OMRIS-8 is a mechanical relay output module that offers 8 channels for switching loads of up to 5 amps at 250 VAC or 30 VDC. These are form C relays, so each of the 8 mechanical relays can be wired as normally open or normally closed. Fusing is not provided; you must provide fusing when wiring the module.
Part of thegroovEPIC® system, the GRV-OMRIS-8 can mechanically switch either AC or DC loads, potentially reducing the number of modules needed. Its 8 channels are all isolated from each other (channel-to-channel isolation). The module offers little or no leakage current when the contacts are open and is suitable for piloting electronic coil contactors.
The GRV-OMRIS-8 module mounts on agroovEPIC chassis with a GRV-EPIC-PR1 processor and a variety ofgroovI/O modules (analog, discrete, and serial) to suit your application needs.
