Agilent/Keysight E1442A

The Agilent/Keysight E1442A is a 64-channel VXI signal routing module built on non-latching armature relay technology for high-density switching and device actuation. Housed in a C-size, 1-slot form factor, this register-based module delivers Form C (SPDT) relay configurations with three independent axial component locations per channel, enabling integrated jumpers, fuses, or resistors for customized circuit topologies. Maximum ratings are 150 V (DC or AC rms), 1 A per switch, and 40 W DC / 40 VA AC per switch.
