Air Products & Controls PAM-1 Multi-Voltage Relay – Flexible Control Module for Multiple Input Voltages

The PAM-1 Multi-Voltage Relay from Air Products & Controls provides a reliable and flexible solution for control and status-feedback applications. Because it supports one of three input voltages (24 VDC, 24 VAC or 120 VAC), this module works well in fire alarm panels, HVAC systems, lighting control, security systems and building‐automation setups. It delivers 10 ampere Form-C contacts, making it capable of switching significant loads while maintaining a compact footprint.

Versatile Input and Output Performance

This relay allows technicians to standardize on a single module across various power supplies. Moreover, it includes a red LED indicator that illuminates when the coil energizes, allowing quick visual verification of status. Additionally, the encapsulated construction helps protect internal components and ensure long‐term reliability in demanding environments.

Easy Installation and Reliable Construction

Installers can mount the PAM-1 using provided self-tapping screw, double-sided adhesive tape, or simply place it in a back‐box. Because the module uses 12-inch flying leads, it connects easily to field wiring. Its compact size and simplified wiring help reduce installation time and streamline service calls.
