OPTO 22 - GRV-IDC-24 _ DC digital input, 24 channels, 15-30 V

Quick Specs:

DC digital input
24 channels
15-30 V

The GRV-IDC-24 digital DC input module can sense the on or off status for 10 - 30 VDC input devices such as proximity switches, push buttons, and auxiliary contacts. The 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

Part of the groov EPIC system, the GRV-IDC-24 mounts on a groov EPIC^® chassis with a GRV-EPIC-PR1 processor and additional discrete, analog, and serial groov I/O modules.

NOTE: For projects that require on/off status only, see the lower cost GRV-IDCS-24 instead.

Note 1: IEC inputs have non-linear impedance. See the tables in the data sheet for typical V-I curves.
Note 2: 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).
