Merlin MVXI1442^ (E1442A)

The Keysight E1442A (Merlin MVXI1442) is a register-based VXI signal routing module that delivers high-density relay switching in a compact C-size, 1-slot form factor. It houses 64 non-latching Form C relays with customizable component locations for jumpers, fuses, and protection networks, making it suitable for device actuation, digital output functions, and complex switching topologies. The module combines a relay component card with a removable terminal block, offering flexible terminal configurations to match application requirements.

– Technical Specifications

• Maximum voltage: 150 V (DC or AC rms)
• Maximum current per switch: 1 A
• Maximum power per switch: 40 W (DC) or 40 VA (AC)
• Relay type: 64 non-latching Form C (SPDT)
• Form factor: C-size, 1-slot VXI module

– Key Features

• 64 Form C relays with three independent axial component locations per relay for internal customization
• Multiple terminal block options: Standard (solder lug, QUIC interface), Option 010 (Form C with customization), Option 020 (screw terminal, Form A access only)
• Legacy terminal options available (106, 116, 126) for backward compatibility
• Internal buses enable flexible circuit layout and simplified wiring
• All three relay terminals accessible through internal bus connections
• Channels operate independently—any combination open or closed

– Typical Applications

• Industrial automation control and device actuation
• Digital output modules requiring multiple independent switching channels
• Signal switching and routing for test and measurement systems
• Applications requiring up to 1 A per channel at 150 V maximum

– Compatibility & Integration

Register-based architecture integrates into standard VXI mainframes. The QUIC interface (on current terminal block options) simplifies field wiring. Removable terminal block design facilitates module installation and replacement. The Merlin MVXI1442 serves as a direct replacement for legacy Keysight/Agilent/HP E1442A installations.
