Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
The Allen Bradley 1756-IV16 is a ControlLogix digital DC sourcing input module. Designed for compatibility with the ControlLogix 1756 chassis system, this module receives discrete signal inputs from field devices and transfers input status to the system backplane. It requires a removable terminal block housing (RTB)—either the 1756-TBNH or 1756-TBSH—prior to mounting into the chassis. The 1756-IV16 provides 16 sourcing input channels configured in 2 groups of 8 points each, operating across a nominal supply voltage of 12/24V DC.
