Agilent / HP / Keysight 34937A

This Channels is the most versatile general purpose switch with 28 Form channels that can switch up to 1A of current. In addition, this module has four Form A channels that can switch up to 5A of current. Each Form A general purpose switch can handle up to 150W, enough for many power line-switching applications. This unit contain latching armature relays where multiple channels can be closed at the same time. Additionally, for switching reactive loads, the optional terminal blocks have pads for snubbing circuits. The built-in relay counter helps predict when relays need to be replaced.
