The PISA-B devices are DIN rail mountable eight channel protection modules with integrated electronic fuses for 24V systems. They distribute the current of a large power source to eight output channels each of lower current and therefore allowing for smaller wires to be used. The output current of each channel can be set individually. Channel 1 and 2 are optimized for loads with large input capacitances. Connect such loads to these channels to avoid false tripping or unexpected switch-OFF such loads. The PISA-B-812-B1 is equipped with a common tripping signaling relay contact that reports tripped channels while the PISA-B-812-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 high-grade reinforced moulded material on the front and of an Aluminium body which permits surrounding temperatures up to +70°C.
