1756-B16 is a Controlloagix discrete input module that operates in voltage categories of 10 to 31.2VDC and has a nominal voltage of 24VDC. This module has sixteen sinking (16) input channels, divided into two (2) groups. This module is installed directly into the 1756 local or remote chassis. Allen Bradley 1756-B16 is a ControlLogix/O module. This 16 point DC input module, with 8 points per group, can be connected to the 1756 ControlLogix chassis. Compatible detachable junction box enclosures or RTBs are 1756-TBNH 20 position NEMA RTB and 1756-TBSH20 position spring clamp RTB. Note that before installation, the user should have a compatible RTB on hand, and install the 1756 chassis and power supply and ground them. The nominal input voltage of the 1756-B16 module is 24 VDC, and the voltage category is 12/24 VDC. Its working voltage range is 10 to 31.2 volts DC, and the total backplane power is 0.56W. 5.1 volt DC current consumption is 100 milliamperes. At 24 volts, the current consumption is 2 milliamperes.

This module is used with a 24VDC input signal, but it can still be used with AC input voltage if appropriate insertion circuits or components are installed. This module supports single rack and vertical controller configurations, suitable for smaller and less important applications. It can also be used for large-scale applications involving higher levels of criticality, such as remote/Q systems or distributed control systems (DCS). This module can even be used as a discrete input module for any ControlLogix configuration, Alen Bradley’s PlantPaXDCS platform. There is almost no limit to the number of installations of this module. The number of instances or installations depends on the memory capacity of the processor and the physical chassis or available slots used.
