Product Description
. . . . . The IAC24A 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.. Opto 22. Opto 22. IAC24A.
