Agilent / HP / Keysight 44477A

This Relay Module provides seven independent Form C Single Pole Double Throw relays for general purpose switching and control of external devices.

With an external power supply, you can use the module to drive remote RF, coaxial, and microwave devices such as the Agilent 876xx, Agilent 8710xx series, and mercury relays.

This module is normally set up to use an external power supply for voltages up to 250V DC, and can be easily configured to use the internal 5V DC power supply.

In applications where the module's voltage or current specifications are going to be exceeded, use the module to drive a properly rated external relay to switch those signals.
