How groov EPIC features help you...


If you spec or buy systems:

  • UL Hazardous Locations approved and ATEX compliant
  • Wide -20 to 70 °C operating temperature range
  • Stainless-steel chassis with 4, 8, or 16 I/O modules—or no I/O at all
  • I/O module density of up to 24 channels per module
  • Multi-featured analog input with voltage, current, and loop sourcing in single module
  • Analog input resolution of 20 bits at 0.1% accuracy over span
  • DC outputs with load switching at 0.4 A per channel @ 70 ºC
  • AC outputs with load switching at 0.5 A per channel @ 70 ºC; blown-fuse detection
  • AC/DC mechanical relay output at 5 A per channel @ 70 ºC
  • Channel-to-channel isolation available 
  • Multiple power supply options including AC, DC, and pass-through
  • Dual, independent Gigabit Ethernet network interfaces 
  • Fully compatible with the SNAP PAC System
  • All products made in the U.S.A.

If you install, commission, or use systems in the field:

  • Integrated high-resolution color touchscreen for commissioning and HMI
  • No PC required for I/O and network configuration or troubleshooting
  • Touch-sensitive pad on I/O modules for configuring and testing
  • Viewable I/O module specs and wiring diagrams
  • Stainless-steel DIN rail or panel mounted chassis
  • Compact footprint with integrated power supply
  • Spring-clamp terminal strip directly atop I/O module accommodating up to 14 AWG wire
  • Integrated wireway with two-position swing-away cover
  • Single module retention screw and strain relief tab built in
  • LED indicators for module health at a glance, and for individual discrete channels
  • Hot-swappable I/O

If you're a developer:

  • Securely shares data among databases, cloud services, PLC systems, and more
  • Real-time, open-source Linux OS
  • Programming choices: flowchart-based PAC Control with scripting  or any IEC 61131-3 compliant language with the CODESYS® Development System
  • Optional secure shell access (SSH) for your own custom-developed application
  • groov View for building and securely viewing operator interfaces from any authorized mobile device or PC with a web browser—and from the EPIC processor's touchscreen
  • Open-source Node-RED for wiring together APIs, cloud applications, and databases with simple data flows, using pre-built nodes
  • Ignition Edge (a product of Inductive Automation®) with OPC-UA drivers to Allen-Bradley® and Siemens® PLC systems—or full Ignition 
  • MQTT transport protocol with Sparkplug payload for efficient data communications
  • RESTful API to groov EPIC processor

If you're an OEM:

  • Remote configuration, troubleshooting, and system visualization from any web browser on any authorized device
