Potter Polarized Relay Module PAM-4
Switch loads on a signal.
The Potter PAM-4 is a polarized relay module with a single SPDT contact rated for 10A. It lets a 9V DC to 40V DC input switch a separate circuit in fire and building-control systems.

A low-voltage signal needs to switch something else.
Fire alarm, HVAC, lighting and other control systems often need a relay to act on a signal. The PAM-4 packages one with its mounting hardware and leads.
Built for control wiring
The PAM-4 combines a single polarized relay with the hardware to mount and wire it.
Single SPDT relay
One form C contact set provides switching between two circuits from a single input.

Maximum input current
Form C contacts are rated 10.0 Amp.
9V DC to 40V DC input
The relay may be energized across this input range, and the input has a built-in polarizing diode.
Encapsulated design
The PAM-4 is an encapsulated polarized device with 10.0 Amp form C contacts.
Leads and hardware included
It comes with five 10" 18AWG flying leads, 5 wire-nuts, mounting screws and double-sided adhesive tape.
