ACS-PCM2-5
The Raychem ACS-30 Advanced Commercial
Control System is a multipoint electronic
control and monitoring system for heat-
tracing used in commercial freeze protection
and flow maintenance applications.
The Raychem ACS-30 system can control up
to 260 circuits with multiple networked ACS-
PCM2-5 panels, with a single ACS-UIT2 user
interface terminal. The ACS-PCM2-5 panel
can directly control up to 5 individual heat-
tracing circuits using electromechanical
relays rated at 30 A up to 277 V.
