Allen-Bradley 1746-IA4 AC Input Module

Allen-Bradley 1746-IA4 AC Input Module

Description

Our wide variety of input, output, and combination modules makes theSLC 500 " family the smart choice for all of your small PLC applications./0 modules are available in a wide variety of densities including 4-, 8-, 16-and 32-point and can interface to AC, DC, and TTL voltage levels. Outputmodules are available with solid state AC, solid state DC, and relay contacttype outputs. For added flexibility, combination modules are also availablein 2-input/2-output, 4-input/4-output, and 6-input/6-output versions.

Designed and tested for industrial applications, our modules are of the highestquality. The modules feature input filtering, optical isolation, and built-insurge protection to enhance the reliability ofoperation in noisy industrialenvironments.

Digital I/O modules are available with 4, 8, 16, or 32 channels and in a wide variety of I/O voltages (including AC, DC, and TTL). Combination modules with 2 inputs/2 outputs, 4 inputs/4 outputs, and 6 inputs/6 outputs are also available.

Terminals on the 4, 8, 12, and 16-channel modules have self-lifting pressure plates that accept two 14 AWG (2 mm2) wires. LED indicators on the front of each module display the status of each I/O point.

32-channel I/O modules are equipped with a 40-pin, MIL-C-83503 type header and a removable wiring connector (1746-N3). The connector can be assembled with the wire type and length of your choice.

Output modules are available with solid-state AC, solid-state DC, and relay contact type outputs. High current solid-state output modules, catalog numbers 1746-OBP16, 1746- OVP16, and 1746-OAP12, have fused commons with a blown fuse LED indication.
