1746-IB16 Allen Bradley Input Module

The Allen-Bradley 1746-IB16 is a medium density DC input module that is used to interface with signal devices that delivers a signal voltage range of 10-30VDC towards each of the input channel of the module. This module features Sixteen (16) input channels, rated for nominal input voltage of 24VDC, grouped into One (1) input group, having a single common terminal. This input module is mounted to any available I/O slot of the 1746-Chassis and draws backplane current of 0.05 A @ 5VDC.

The 1746-IB16 supports sinking wiring configuration only. It cab used to interface with electrical components such as switches including limit, proximity, pushbutton devices as well as auxiliary contacts of relays, contactors and other electronic devices. Each of the input channels of the 1746-IB16 exhibits a common signal delay duration of 8 ms for both On and OFF transitions, with maximum OFF-state voltage of 5VDC and maximum OFF-state current of 1 mA while the module’s nominal input current is 8 mA @ 24VDC.

The number of installation instances of the 1746-IB16 varies according to the SLC500 CPU installed. Specifically, depending on the number of I/O supported by the CPU memory. This module may also be installed locally, along the rack where the SLC 500 CPU is installed or in a Distribute I/O chassis, along a 1746 Communication adapter such as Remote I/O (RIO) and Ethernet adapter modules. This module comes with status LED indicators that provided indications to the actuation of each of the input channels for simplified monitoring and troubleshooting.
