Application Scenarios
In a metal-pressing cell, a worn coupling can slowly let the flywheel exceed its safe-speed limit long before any digital guard switch reacts. A standard analog card would report the speed, but the safety controller could not legally act on that value. The 1734-IE4S changes the game: the tachometer channel reads shaft speed, the pressure transmitter feeds another channel, and the module delivers both values into the safety task over CIP Safety. When a safe-speed boundary is crossed, the press initiates a controlled stop instead of relying on an operator or a standard PLC scan. The same module flags a degraded shield or broken transmitter wire as a safety-relevant fault—not just as “a number that looks odd.” That is the difference between process monitoring and real functional safety.
