The Keysight E1442A is a C-size VXI switch module housing 64 non-latching Form C (SPDT) relays for signal routing, device actuation, and digital output functions in automated test systems. This register-based, 1-slot module delivers flexible switching topologies with field-customizable component locations and multiple terminal block options including QUIC interfaces for simplified wiring.
– Technical Specifications
• Relay Type: Non-latching armature relays, Form C (SPDT)
• Channel Count: 64 channels
• Maximum Voltage: 150 V (DC or AC rms)
• Maximum Current per Switch: 1 A
• Maximum Power Rating (DC): 40 W per switch
• Maximum Power Rating (AC): 40 VA per switch
• Form Factor: C-size, 1-slot VXI module
• Internal Resources: Three independent axial component locations per relay for jumpers, fuses, and pullup/pulldown or protection resistors
– Key Features
• Any combination of relay channels can be independently opened or closed
• Removable, customizable terminal block accommodates field modifications
• Internal buses provide enhanced circuit layout flexibility
• Multiple terminal block configurations available: standard solder lugs with Form C access, QUIC easy-connect interface, screw terminals with Form A (SPST) access, and solder terminals with integrated signal conditioning
• Non-QUIC front panel options (old style) available for legacy system integration
– Typical Applications
• General-purpose signal routing and multiplexing
• External device actuation and control
• Digital output functionality within test systems
• Multi-topology switching configurations
• Custom signal conditioning via component customization
– Compatibility & Integration
Designed for integration into VXIbus systems requiring a C-size VXI mainframe. The modular terminal block design supports both modern QUIC connectors and legacy screw/solder interfaces, enabling deployment across mixed-generation test platforms.
