Analog voltage input, 24 channels, 8 configurable input ranges from ±160 VDC to ±1.25 VDC

Production Specification

The GRV-IV-24 analog module can be configured for any one of the following eight input ranges on each of its 24 input channels:
  • ±160.0 VDC
  • ±80.0 VDC
  • ±40.0 VDC
  • ±20.0 VDC
  • ±10.0 VDC
  • ±5.0 VDC
  • ±2.5 VDC
  • ±1.25 VDC
Note that all channels share a common reference terminal.

Part of the groov EPIC® system, the GRV-IV-24 module mounts on a groov EPIC chassis together with a GRV-EPIC-PR1 processor and other analog, discrete, and serial groov I/O modules.
