Opto 22 releases GRV-IVI-12, GRV-IRTD-8 and GRV-IDCSW-12 input/output modules

October 22, 2019 – Opto 22 announced the release of three groov EPIC input/output modules, extending an industrial I/O portfolio. For system integrators and engineers, the I/O modules provide more options for bringing existing devices into groov EPIC, as well as meeting requirements for temperature control applications. They also include designs for mixed signal types, signal isolation, and channel density:

GRV-IDCSW-12 (discrete input, 12 channels, DC contact switch status) monitors the open/closed status of dry contact switches, and provides the necessary excitation voltage to power the circuit. This module is suitable for monitoring distributed IT equipment, benchtop analyzers, motor run/stop relays, or any device that offers only a dry contact for status. Because there’s no need to install separate power supplies to drive these dry contacts—since wetting and monitoring are both provided.

GRV-IVI-12 (analog voltage input, 12 channels, ±1.25 to ±160 V, channel-to-channel isolation): With 12 isolated channels, each configurable to one of eight ranges from ±1.25 to ±160 V, this module eliminates the need to segregate I/O signals over multiple modules, providing reduction for mixed voltage applications. The GRV-IVI-12 has 20-bit resolution and is accurate to 0.1% of the configured range. It includes options for scaling, filtering, averaging, and more, speeding development time and distributing computation functions down to the I/O module.

GRV-IRTD-8 (analog input, 8 channels, temperature/RTD or resistor) increases options for accuracy and I/O density in temperature applications. It provides 8 channels for 2- and 3-wire RTD inputs, with a maximum range of –200 °C to 850 °C. Users can take advantage of multiple fixed ranges or one of two auto-ranging methods to simplify configuration. GRV-IRTD-8 can also be used for resistance measurements, with accuracy ranging from 4.2 Ohms at the 8K Ohm input range to 0.058 Ohms at the 10 Ohm range for 3-wire RTDs.

PAC Project 10.2003 or the Opto 22 Library Package for CODESYS v1.0.2.0 are required for full support of these modules. These new modules include the following features:

  • Two-position, hinged LED module cover that indicates module status and covers field terminations
  • Touch-sensitive pad to trigger module information display on the groov EPIC processor
  • Removable top-mounted connector with single, captive retention screw
  • Spring-clamp field wiring terminals
  • Hot swappable for installation and removal without turning off or stopping the system
  • UL Hazardous Locations approved and ATEX compliant
  • Wide operating temperature range of –20 to +70 °C
  • Individually calibrated and factory tested twice—no statistical testing

With this latest module release, users can choose from almost 40 types of groov I/O modules to support their application requirements. Combined with its variety of embedded software tools for control, visualization and connectivity, this extensive I/O family makes groov EPIC a tool for industrial automation and IIoT (industrial internet of things) systems.
