Digital output module GRV-OACIS-12

12-OEPICenergy monitoring and control

Overview

The GRV-OACIS-12 is a groov EPIC digital AC output module that provides 12 independent on/off channels for switching 12–250 VAC loads. It is intended for simple, lower-cost switching applications and integrates transient protection and zero-crossing switching to reduce switching transients and protect control electronics.

Key features

• 12 independent AC discrete output channels (on/off only)
• Zero-voltage turn-on and zero-current turn-off (zero-crossing) to minimize switching transients
• 300 V working field-to-logic isolation and 1500 V transient protection (1 minute)
• Module cover with LED status indicator and touch-sensitive pad for module info and wiring diagrams via the groov EPIC processor
• Mounts on groov EPIC chassis; compatible with GRV-EPIC-PR1 processor and other groov I/O modules
• UL/cUL listed; compliant with ATEX, Low Voltage, EMC CE and UKCA directives; RoHS and other approvals
• Factory tested twice before shipment; most modules carry a lifetime warranty

Applications

• OEM and machine design
• Process control and machine monitoring
• Power and energy monitoring
• Predictive maintenance and remote installations (water/wastewater, oil & gas)
• SCADA and IIoT applications
