Data Sheet

Production Specification

Part of the groov EPIC® system, 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. The module cover includes an LED that indicates status and a touch-sensitive pad. Touch the pad and the groov EPIC processor displays information about the module, including specifications and a wiring diagram.

For current outputs, the GRV-OVMALC-8 also provides an isolated loop supply.

The GRV-OVMALC-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.  

All groov I/O modules are UL/cUL listed and compliant with the ATEX, Low Voltage, and EMC CE and UKCA directives. Each module is factory tested twice before shipment and most modules are guaranteed for life.

Opto Products, like GRV-OVMALC-8, are ideal for OEMs and machine designers, process control, machine monitoring, power and energy monitoring, predictive maintenance, remote installations like water-wastewater and oil & gas, SCADA, and industrial internet of things applications.
