A newly developed protection
module from PULS enables users to
connect PLCs or other critical
equipment directly to one 24V power
supply and, at the same time, protect
up to four other associated circuits.
In the event of one or more of these circuits becoming overloaded, the PISA module interrupts the current to prevent the output voltage to the PLC being adversely affected.
Each output channel is fitted with an internal fuse conforming to UL248 and meeting the requirements of Branch Circuit Protection UL508A section 31.1.2.
PISA also serves as a diagnostic tool by identifying which circuit has failed, making fault finding easy and reducing downtime.
