Description

Overview

  • The GRV-IMA-24 is a groov EPIC analog input module delivering 24 precision current input channels with per-channel software-configurable ranges.
  • Designed for industrial control, OEM machinery, process monitoring, power & energy, predictive maintenance, remote installations, SCADA and IIoT systems.


Applications

  • OEM and machine builders
  • Process control and automation
  • Power and energy monitoring
  • Water/wastewater and remote field installations (oil & gas)
  • SCADA and IIoT data acquisition


Key features

  • 24 independent analog current input channels.
  • Per-channel selectable ranges: ±20 mA, 0–20 mA and 4–20 mA (software configurable).
  • Module cover with status LED and touch-sensitive pad to display module info and wiring diagram on the groov EPIC processor.
  • DIN-compatible mounting on groov EPIC chassis alongside other groov I/O modules and GRV-EPIC-PR1 processor.
  • Hardware and software filtering options; precise resolution and high common-mode rejection for industrial signals.


Technical specifications

  • Number of channels: 24.
  • Input ranges (per channel): -20 to +20 mA; 0 to 20 mA; 4 to 20 mA.
  • Over-range limits: -22 mA to +22 mA; 0.0 to 22.0 mA; 2.0 mA to 22.0 mA (depending on selected range).
  • Resolution: 0.02 µA (20-bit).
  • Accuracy: ±20 µA.
  • Input voltage drop (nominal, impedance ±20%): 5.5 V nominal @ 20 mA (≈275 Ω).
  • Hardware input filter: -3 dB at 140 Hz.
  • Analog data filtering: -3 dB @ 2.4 Hz / -25 dB @ 60 Hz; software filtering: Simple Moving Average (1–32 readings) and Weighted Average (1–4096 per module).
  • Data refresh time: 450 ms (step response time = 450 ms × SMA value; default SMA = 4).
  • Common mode rejection: > -120 dB.
  • Maximum survivable input: ±32 V.
  • Isolation (field-to-logic): 300 V working, 1500 V transient (1 minute).
  • Isolation (channel-to-channel): 300 V between group A (channels 0–11) and group B (channels 12–23).
  • Chassis power consumption: 1.0 W (module).
  • Minimum firmware / software: groov EPIC firmware 1.0.0; PAC Project 10.0000; Library Package for CODESYS 1.0.0.0.
  • Wire size: 28–14 AWG; wire strip length: 8–9 mm.
  • Connector torques: connector screw 2.5 in-lb (0.28 N·m); hold-down screw 3.5 in-lb (0.4 N·m).
  • Operating temperature: -20 °C to +70 °C; storage: -40 °C to +85 °C.
  • Relative humidity (non-condensing): 5–95%.
  • MTBF (min, 25 °C): 1.2 million hours.


Compliance & warranty

  • Factory tested twice; UL/cUL listed (Class 1, Div 2); CE: ATEX Category 3 Zone 2; RoHS; DFARS; CB Scheme; UKCA.
  • Most modules carry a lifetime warranty.
