Analog output, 8 channels, voltage or current, channel-to-channel isolation, field or chassis-powered loop

Production Specification

The GRV-OVMAILP-8 analog output module has 8 channels, individually configurable for any one of five voltage or current output ranges:
  • 0 to 5 VDC 
  • 0 to 10 VDC
  • 0 to 22 mA
  • 4 to 20 mA 
  • 0 to 20 mA 
The module provided channel-to-channel isolation. Each range has 4096 counts (12 bits) of resolution. See the Specifications tab for more information.

The GRV-OVMAILP-8 can power current loops from an internal isolated loop supply powered from the chassis or, on a channel-by-channel basis, from an externally connected loop supply of 22-32 VDC. 

Part of the groov EPIC® system, the GRV-OVMAILP-8 mounts on a groov EPIC chassis with a GRV-EPIC-PR1 processor and other analog, discrete, and serial groov I/O modules, to give you the mix of signals you need.
