The Keysight E1364A is a 16-channel Form C switch module designed for VXI instrument systems. This B-size, 1-slot, register-based module employs latching armature relays to maintain switch positions without continuous power, making it ideal for switching, scanning, control, and digital output applications. Each channel supports 250 V, 1 A DC or AC signals with a maximum power rating of 40 W DC / 40 VA AC per switch. The module can handle up to 320 W DC or 320 VA AC total power dissipation.
