The Keysight/Agilent/HP E1343A is a 16-channel, general-purpose, high-voltage relay multiplexer engineered for integration into automated test systems. Operating as a B-size, 1-slot VXI module, it delivers flexible signal routing across configurations including a single 1×16 three-wire multiplexer, two independent 1×8 three-wire multiplexers, or a single 1×8 six-wire multiplexer. The module combines a component card with a screw terminal block, providing direct access to all 16 channels via common high, low, and guard terminals plus analog bus connections.
Technical Specifications
• Module Type: VXI (B-size, 1-slot)
• Channel Density: 16 channels (3-wire) or 8 channels (4-wire)
• Maximum Voltage: 250 Vdc (any terminal to any other terminal or chassis)
• Relay Technology: Reed relays with break-before-make switching
• Scanning Rate: 350 channels/s (typical)
• Power States: Relays open at power-down and power-up
• Terminal Block: Screw terminals, 16–26 AWG (0.5–1.5 mm)
– Key Features
• Configurable architecture supports single 1×16, dual 1×8, or mixed 1×8 six-wire topologies
• High-voltage capability rated to 250 Vdc across all terminal pairs and chassis
• Reed relay construction provides reliable break-before-make operation
• Screw terminal interface simplifies field wiring
• Analog bus connectivity for seamless mainframe integration
– Typical Applications
High-voltage signal routing in automated test environments, including DC power switching, sensor multiplexing, and general-purpose relay control requiring voltage isolation and multi-channel flexibility.
– Compatibility & Integration
The E1343A component card (E1343-66201) shares architecture with the E1344A. Terminal block design determines matrix configuration; identical switch cards support the E1345A, E1346A, E1347A, E1355A, and E1356A with equivalent performance specifications. Integration with Keysight E1300B or E1301B B-size mainframes requires the analog bus cable shipped with the E1326B DMM. C-size mainframe deployment uses the E1403C active adapter.
