English | IAC24A AC Input, 180-280 VAC, 24 VDC Logic |
  |
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.
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
