AC/DC discrete input, 24 channels, 2.0-16 V AC/DC, on/off state only

Production Specification

The GRV-IACDCTTLS-24 digital input module can sense the on or off status for up to 24 AC or DC devices with signals between 2.0 and 16 volts. This module provides input on/off state only, offering a lower-cost option for projects that require only point states. Note that the module's 24 channels are not isolated from each other; all channels share a common reference terminal.

The GRV-IACDCTTLS-24 mounts on a groov EPIC® chassis alongside a GRV-EPIC-PR1 processor and other digital, analog, and serial groov I/O modules.

NOTE: If your application requires additional features (latching, totalizing, and more), see the GRV-IACDCTTL-24 module.
