Puls PISA-M-4CL2 Manual

RODUCT ESCRIPTION
The PISA-M devices are miniature 4-channel protection
modules for 24 V and 12 V systems providing all benefits
of electronic circuit breakers in a tiny DIN rail mountable
housing: Voltage-dependent
independent output channels in one device – including
selection of tripping characteristic combined with different
options for remote signaling and communication, enabling
remote configuration, monitoring and control.
The PISA-M supports multiple, user-selectable, signaling
and communication methods, allowing the selection of
simple alerts and reset function.
All PISA-M devices are equipped with push-in terminals,
which are optimised for automated wiring and allow fast
and safe installation.
