The Agilent/Keysight 59306A Relay Actuator is a programmable switching control unit housing six Form-C relays for automated test and measurement systems. It provides both front-panel manual operation and remote HP-IB control, enabling flexible integration into test benches, data acquisition setups, and signal-path optimization configurations where precise relay switching is essential.
– Technical Specifications
Relay Configuration
• Six Form-C relays
• Contact rating: 0.5 A at 28 V dc or 115 V ac
• Settling time: 50 ms
• Maximum switching rate: 20 switches per second
Control & Interface
• Local control via front-panel pushbutton switches
• Remote control via HP-IB (24-pin connector)
• Octal address configurable via rear-panel switches; typical address 7 octal

Environmental
• Operating temperature: 0 to 50°C
Indicators & Controls
• Front-panel indicator bulbs (5 V, 0.06 A, T-1 3/4) per relay state
• Power and Remote indicator lights (6 V, 0.04 A wire-terminal bulbs)
• Local-reset pushbutton for immediate operator control and remote-to-local transfer
– Key Features
• Dual-mode operation: manual button control or remote HP-IB command
• Front-panel relay status indication via illuminated pushbuttons
• Terminal interface: 18 binding posts (4 mm banana jacks) for relay contacts and signal connections
• Local lockout capability prevents unauthorized remote control
• Time-out error detection for bus faults, address conflicts, or hardware malfunction
• Proximity placement capability via HP-IB reduces signal losses in test signal paths
– Typical Applications
• Automated test system switching and control
• Signal routing in RF/microwave measurement setups
• Data acquisition system relay switching
• Process control environments requiring reliable contact switching
– Compatibility & Integration
The 59306A integrates with electrically controlled attenuators, RF switches, and microwave components including the 8761A/B coaxial switch family and 8494A–8496G/H programmable step attenuators.
