Allen Bradley 1756-IB16 ControlLogix 16 Pt 12/24V DC D/I Module
The 1756-IB16 is a ControlLogix Discrete input module which operate at a voltage category of 10 to 31.2 VDC with a nominal voltage of 24VDC. This module has Sixteen sinking (16) input channels in Two (2) groups. This module is directly installed to a 1756 local or remote chassis.This module may be used as Discrete Input module of any ControlLogix configuration even, PlantPaX DCS platform of Allen-Bradley. There is virtually no limit with the number of installations of this module. The number of instances or installation depends on the Processor’s memory capability and the Physical chassis used or available slot.

Description:
The Allen-Bradley 1756-IB16 is a DC sinking input module that operates at a nominal input voltage of 24VDC. This module is used with 24VDCinput signals however, may still be used with AC input voltages provided that an appropriate interposing circuitry or component is installed.
This module supports single-rack, stand-alone controller configuration for smaller and less critical application. It may also be used in larger applications where a higher degree of criticality is involved such a Remote I/O system or a Distributed Control System (DCS).
The 1756-IB16 uses a Removable Terminal lock that provides a modular way of terminating input signals. It may be replaced with RTB part number of 1756-TBNH 1756-TBSH. It has a change of state property that is user-configurable and useful in applications that require immediate action when a certain input signal has changed to the defined state. Change of State (COS) bypasses the normal scan cycle of the processor for a faster logic execution.
