Opto22 groov EPIC I/O modules

Opto 22 has released three groov EPIC I/O modules for switching, analog and temperature inputs.

The GRV-IDCSW-12 module, providing 12 discrete input channels and 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 analysers, motor run/stop relays or any device that offers only a dry contact for status.

The GRV-IVI-12 module provides 12 analog voltage inputs, ±1.25 to ±160 V. Each channel is configurable to one of eight ranges from ±1.25 to ±160 V and eliminates the need to segregate I/O signals over multiple modules, providing cost and space reduction for mixed voltage applications. The GRV-IVI-12 has 20-bit resolution and is accurate to 0.1% of the configured range, and includes options for scaling, filtering and averaging.

The GRV-IRTD-8 is an 8-channel analog input module for RTD or resistor temperature inputs, increasing options for accuracy and I/O density in temperature applications. It provides eight channels for 2- and 3-wire RTD inputs, with a maximum range of -200 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 high-resolution resistance measurements, with accuracy ranging from 4.2Ω at the 8KΩ input range to 0.058Ω at the 10Ω 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.
