Opto 22 released three groov EPIC input/output modules. For system integrators and engineers, the new I/O modules provide more options for bringing existing devices into groov EPIC, as well as meeting requirements for temperature control applications.
The new releases include:
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 can monitor 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 — this module can save time, money, space, and installation effort.
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 significant cost and space reduction for mixed voltage applications. The GRV-IVI-12has 20-bit resolution and is accurate to 0.1 percent 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 high-resolution 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 v22.214.171.124 are required for full support of these modules.
GRV-IDCSW-12 ($450), GRV-IRTD-8 ($855), and GRV-IVI-12 ($995) will be available on October 28.
