GRV-OMRIS-8

$375.00 (USA and Canada only)

Availability: In stock
AC/DC discrete output, 8 channels, electromechanical relay, 0-250 VAC/5-30 VDC, 5 A

Production Specification

Part of the groov EPIC® system, 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. 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.

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 a groov EPIC chassis with a GRV-EPIC-PR1 processor and a variety of groov I/O modules (analog, discrete, and serial) to suit your application needs.

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.

Case Study: netDNA Automates Water Management

View in HTML

In the oil and gas industry, technological advances like hydraulic fracturing (fracking) and horizontal drilling have caused a boom in exploration and drilling. The initial “gold rush” approach to oil and gas development focused on people resources, with most work done manually.

But now companies are looking to add automation in the field, especially for water pumping and treatment, key ingredients in successful unconventional oil and natural gas production. In an industry with remote, widely separated, and changeable operations, automation and data communications aren't easy. 

In this case study, read how netDNA automated their customer's trailer-based pumping units and provided data communications, using groov EPIC edge programmable industrial controllers and I/O, plus IIoT-friendly technologies like Node-RED and MQTT.
