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...
ABB HESG448230R1/G 216EA61B is an analogue input unit designed for the RE. 216 digital protection and control system. The unit receives analogue measured variables from the 216GW61 input transformer module, digitises them via an A/D converter, and transfers the digitised signal data to the system's B448C parallel bus.
The module functions as a core measurement acquisition unit within the RE. 216 hardware architecture. Operating with an internal supply voltage of 5 V derived from the rack's main 24 V DC auxiliary supply, the ABB HESG448230R1/G 216EA61B processes analogue input voltages ranging from -40 V to +40 V. Digitised measurement channels are subsequently assigned to active protection and control functions stored within the processing unit via the user interface software.
