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.

Output Supply Voltage Range : 20–30vdc
Output Current: 50 mA

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
