OPTO 22 GRV-IMA-24 Open Box

Part of the groov EPIC^® system, the GRV-IMA-24 analog input module is part of the groov EPIC^® system. This module provides 24 channels of analog current input with an input range of ±20 mA, 0–20 mA, and 4–20 mA. Ranges are software configurable. The module cover includes an LED that indicates status and a touch-sensitive pad. Touch the pad and the groov EPIC processor displays information about the module, including specifications and a wiring diagram.

The GRV-IDC-24 module is leakage tolerant and offers a full set of features, including:
– On/off state
– On/off latching
– On/off totalization
– Frequency measurement
– Period measurement
– Pulse measurement

The GRV-IMA-24 mounts on a groov EPIC chassis with other analog, discrete, and serial groov I/O modules and a GRV-EPIC-PR1 processor.

All groov I/O modules are UL/cUL listed and compliant with the ATEX, Low Voltage, and EMC CE and UKCA directives. Each module is factory tested twice before shipment and most modules are guaranteed for life.
