Data Sheet

Production Specification

Part of the groov EPIC® system, the GRV-IACDCTTL-24 AC/DC discrete input module can sense the on or off status for up to 24 AC or DC devices between 2.0 and 16 volts. Its 24 channels are not isolated from each other; all channels share a common reference terminal. 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-IACDCTTL-24 module offers a full set of features:
  • On/off state
  • On/off latching
  • On/off totalization
  • Frequency measurement 
  • Period measurement 
  • Pulse measurement

The GRV-IACDCTTL-24 module mounts on a groov EPIC® chassis alongside a GRV-EPIC-PR1 processor and other digital, analog, and serial groov I/O modules to provide the mix of signals you need at any location. 

NOTE: For projects with simple requirements, see the GRV-IACDCTTLS-24 module, which is lower cost and offers on and off sensing only.

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.

Opto Products, like GRV-IACDCTTL-24, are ideal for OEMs and machine designers, process control, machine monitoring, power and energy monitoring, predictive maintenance, remote installations like water-wastewater and oil & gas, SCADA, and industrial internet of things applications.

a The GRV-IACDCTTL-24 is primarily intended for use as a polarity-insensitive low voltage DC input module. It can be used with AC input voltages by reading the On Latch or Off Latch when discrete input latching is enabled. This also applies when using the various features other than state and latches.
b For use in hazardous locations, equipment must be mounted in an enclosure that meets the requirements of the National Electrical Code, ANSI/NFPA 70, and ANSI/ISA-61010-1 (82.02.01)

Opto Products are ideal for OEMs and machine designers, process control, machine monitoring, power and energy monitoring, predictive maintenance, remote installations like water-wastewater and oil & gas, SCADA, and industrial internet of things applications.
