OPTO 22 – GRV-OVMALC-8 _ Analog output, 8 channels, voltage or current, chassis-powered loop
Quick Specs:
- Analog output
- 8 channels
- voltage or current
- chassis-powered loop
The GRV-OVMALC-8 analog output module has 8 channels, individually configurable for any one of seven voltage or current output ranges:
- 0 to 5 VDC
- 0 to 10 VDC
- -5 to +5 VDC
- -10 to +10 VDC
- 0 to 22 mA
- 4 to 20 mA
- 0 to 20 mA
Each range has 4096 counts (12 bits) of resolution. See the Specifications tab for more information.
For current outputs, the GRV-OVMALC-8 also provides an isolated loop supply.
Part of thegroovEPIC® system, the GRV-OVMALC-8 mounts on agroovEPIC chassis with a GRV-EPIC-PR1 processor and other analog, discrete, and serialgroovI/O modules, to give you the mix of signals you need.
