OPTO 22 - IAC15A _ G1 AC Digital Input 180-280 VAC, 15 VDC Logic

Quick Specs:

G1 AC Digital Input 180-280 VAC
15 VDC Logic

G1 I/O family

The IAC15A input module is used to sense ON/OFF AC voltage levels at 180-280 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

IAC15A modules are not for use with Opto 22 brains.
