TEMECULA, Calif. — Opto 22 announces the release of three new groov EPIC® input/output modules, further extending an already comprehensive industrial I/O portfolio. For system integrators and engineers, the new I/O modules provide more options for bringing existing devices into groov EPIC as well as meeting precise requirements for temperature control applications. They also include budget-beating 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 ideal 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 — this module can save considerable time, money, space, and installation effort.
GRV-IVI-12 (analog voltage input, 12 channels, ±1.25 to ±160 V, channel-to-channel isolation) features 12 isolated channels, each configurable to one of eight ranges from ±1.25 to ±160 V, which allows this module to eliminate the need to segregate I/O signals over multiple modules, providing significant 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. 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 eight channels for 2- and 3-wire RTD inputs with a maximum range of minus 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 v188.8.131.52 are required for full support of these modules.
Opto 22 designs groov I/O modules with the end user in mind, including many features to make them easy to specify, install, configure and support for even the most challenging applications. These new modules continue that tradition with 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; and
• Guaranteed for life.
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 one of the most versatile tools for industrial automation and IIoT (industrial internet of things) systems.
