Availability: In stock
G1 AC Digital Input, 90-140 VAC, 24 VDC Logic

Production Specification

G1 I/O Family

The IAC24 input module is used to sense ON/OFF AC voltage levels at 90-140 VAC. All AC input modules are designed with filtering on the input and a hysteresis amplifier for high noise rejection and transient-free clean switching. Each module provides up to 4000 volts (transient) of optical isolation between the field inputs and the logic output of the circuit.

Typical uses and applications include sensing the presence or absence of voltage or sensing contact closures from sources such as:

  • Proximity switches
  • Limit switches
  • Float switches
  • Selector switches
  • Push buttons
  • Toggle switches
  • Thermostats


IAC24 modules are not for use with Opto 22 brains.
