Air Products & Controls, Inc. PAM-1, PAM-2, and PAM-4 Multi-
Voltage Relay Modules are encapsulated multi-voltage
devices. The PAM-1 relay provides 10.0 Amp Form-C contacts
and may be energized by one of three input voltages: 24 VAC,
24 VDC, or 115 VAC. The PAM-2 relay provides 7.0 Amp
Form-C contacts and may be energized by one of two input
voltages: 12 VDC or 24 VDC. The PAM-4 relay provides 10.0
Amp Form-C contacts and may be energized by a wide voltage
range from 9 VDC to 40 VDC.
A red LED is provided on both models. When illuminated, it
indicates the relay coil is energized.
Either model may be mounted by using the double-sided adhesive
tape, the self-drilling screw, or by placing loosely in a
backbox.
PAM-1, PAM-2, and PAM-4 Relay Modules are ideal for applications
where remote relays are required for control or status
feedback. They are suitable for use with HVAC, temperature
control, fire alarm, security, energy management, and lighting
control systems.
