Product Description
The PISA-B devices are DIN rail mountable eight channel protection modules with integrated electronic fuses for 24V systems. They distribute the current from one large power source to eight NEC Class 2 output circuits, which results in reduced fire safety efforts and easier regulatory testing as well as approval processes for the end equipment. Channel 1 and 2 are optimized for loads with large input capacitances. Connect such loads to these channels to avoid false tripping or unexpected switchoff such loads. The PISA-B-8CL2-B1 is equipped with a common tripping signaling relay contact that reports tripped channels, while the PISA-B-8CL2-B4 has a digital coded signal output built in for this function. All PISA-B devices are equipped with push-in terminals, which are optimized for automated wiring. The mechanically robust housing is made of a highgrade, reinforced molded material on the front and of an aluminum body, which permits surrounding temperatures up to +70°C.
