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 Bently Nevada 136294-01 is an isolated +4 to +20 mA I/O module with internal terminations designed for processing machine-critical parameters in the 3500 Machinery Protection System. Installed in the rear slot of the 3500 rack directly behind the 3500/62 Process Variable Monitor main module, it accepts up to 6 channels of 4 to 20 mA DC input signals from field transmitters. The 136294-01 provides 500 Volts of galvanic isolation to protect system architecture against ground loops and signal interference while transferring conditioned parameter data to the main monitor board for alarm setpoint evaluation and machinery protection.
