The Keysight Z2309A is a 72-channel digital output and relay driver module designed for VXI instrumentation systems. This B-size, single-slot VXI module features open-collector outputs capable of switching up to 32 V with a maximum sink current of 200 mA per channel, all referenced to chassis ground. External pull-up resistors are required when operating as digital outputs. The module includes integrated flyback protection for relay coil suppression, making it ideal for controlling relays, solenoids, and other switching devices in automated test environments.

– Key Features
• On-board jumper selection of +5 V, +12 V, or +24 V VXI power supply rails for external device powering. Note: +24 V supply unavailable on B-size mainframes without external supply; available on C-size mainframes only.
• Limited power availability on module faceplate—external power recommended for high-current applications
• SCPI-compatible command set for individual channel control and dual-output latching relay sequences
• Register-based architecture for direct control via VXI backplane interface
– Typical Applications
• Relay and solenoid control in automated test systems
• Digital switching of external power supplies and loads
• Industrial control interfacing within VXI mainframes
• Latching relay actuation via synchronized dual-channel outputs
– Compatibility & Integration
Full VXI plug-and-play driver support with SCPI command compatibility enables straightforward integration into existing test automation frameworks. Compatible with all standard VXI mainframes meeting B-size or larger slot requirements.
