Safety relay module HR5S series

DIN rail mounted

THE NEW IDEC H5RS CATEGORY 2 SAFETY RELAY BREAKS NEW GROUND IN THE WORLD OF SINGLE CHANNEL ARCHITECTURE Most competitive relays simply offer a feedback check on the circuit to verify that the machine is safe to start. They leave any requirement for test channels devices external devices. Now with the New IDEC HR5S C2B you can find output indication of fault detection and additional outputs to shut down the safety channels when a fault occurs. All this with discrete fault reset and restart functions. What does this mean for you? Well if the machine has an error in the safety circuit at start up, or on the demand on the safety function , then once the fault is detected another single channel is isolated to remove the control. Lets call it Category 2 the way it should be done all in the IDEC HR5S safety relay. Degree of contribution to risk reduction in a safety system is categorized by performance levels. In category 2 architecture, PL=c or PL=d control system can be acheived. Risk assessment must be performed to check the perfomance level (PLr) required for the equipment. PLr=C exists especially in food and packaging machines, semiconductor manufacturing equipment, and other production equipment and locations.
