GENERAL DESCRIPTION
SHORT-FORM DATA
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 switch-
off 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 high-
grade, reinforced molded material on the front and
of an aluminum body, which permits surrounding
temperatures up to +70°C.
