Allen-Bradley 1746-ITB16 16-Channel Input Module

1746-ITB16 is a 16-channel Fast-Response DC input module for Allen-Bradley SLC 500 controllers. This sinking 24V DC input card provides 16 discrete input points that report their on/off state to the 1746 I/O backplane, enabling real-time digital I/O within a SLC 500 system. Designed for direct connection to 24V DC field devices, the module is part of the SLC I/O family and is intended to be used in a compatible 1746 backplane chassis. It is designed for use in standard SLC 500 racks, integrating with other DC input modules to expand the controller's capability to monitor binary signals. Key specifications include 16 input channels; 24V DC input; sinking configuration; fast-response inputs. Typical applications include expanding a controller’s capability to read binary signals from sensors and switches in manufacturing, packaging, or process lines where fast state changes must be captured by the PLC.
