Quad Pak I/O family
The IAC5AQ is a 4-channel AC digital input. It accepts input voltage of 180-280 VAC and uses 5 VDC logic. It is compatible with Opto 22 Optomux, Pamux, and Mistic protocol brain boards and mounting racks, as well as racks using a direct cable connection to a computer. This module can also be used with a Raspberry Pi, the Digital I/O Carrier Board (part number OPTO-P1-40P), and the PB16HQ mounting rack.
Quad Pak modules contain the equivalent of four single-channel I/O circuits in a single package. Each Quad Pak module can be divided into two pairs, with each pair sharing a common connection.
Quad Pak modules plug into Quad Pak I/O mounting racks. They are not compatible with single-channel racks or SNAP racks.
AC input modules are used for sensing ON/OFF AC voltages. 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 4,000 Vrms of optical isolation between field inputs and the logic side of the circuit.
