Air Products and Controls, Inc. PAM-1, PAM-2, and PAM-4 Multi-Voltage Relay Modules are encapsulated multi-voltagedevices. The PAM-1 relay provides 10.0 Amp Form-C contactsand may be energized by one of three input voltages: 24 VAC,24 VDC, or 115 VAC. The PAM-2 relay provides 7.0 AmpForm-C contacts and may be energized by one of two inputvoltages: 12 VDC or 24 VDC. The PAM-4 relay provides 10.0Amp Form-C contacts and may be energized by a wide voltagerange from 9 VDC to 40 VDC A red LED is provided on both models. When illuminated, itindicates the relay coil is energized. Either model may be mounted by using the double-sided adhe-sive tape, the self-drilling screw, or by placing loosely in a backbox. PAM-1, PAM-2, and PAM-4 Relay Modules are ideal for appli-cations where remote relays are required for control or statusfeedback. They are suitable for use with HVAC, temperaturecontrol, fire alarm, security, energy management, and lightingcontrol systems.
