This unit
The Keithley 7055 Screw Terminal Card is a quick-disconnect interface accessory that provides screw terminal connections for routing external signals to scanner card relay functions within Keithley mainframe systems. It is the physical termination point between external wiring and compatible scanner cards, enabling secure signal switching in multi-channel scanning applications.
Technical Specifications
Maximum Wire Size: #18 AWG
Contact Configuration: Two Form A (SPST normally open) contacts per channel
Maximum Signal Level: 150 V, 250 mA, 10 VA (resistive load)
Contact Life: >10⁸ closures (cold switching); >10⁷ closures at maximum signal levels
Contact Resistance: <2 Ω to rated life
Contact Potential: <100 µV per contact pair input to output with copper leads (<50 µV typical)
Actuation Time: 10¹⁵ Ω, 10¹⁰ Ω, 10¹⁰ Ω, <150 pF
Common Mode Voltage: 150 V peak
Dimensions: 32 mm H × 114 mm W × 272 mm L (1.26 in. × 4.5 in. × 10.75 in.)
Net Weight: 0.27 kg (9.5 oz.)
Connector Type: Screw terminal
Key Features
Modular screw terminal interface for relay-switched signal routing
Supports 1-pole or 2-pole switching configurations
Enables 10 channels (2-pole mode) or 20 channels (1-pole mode) when paired with Model 7056
Low contact resistance and low contact potential for signal integrity
High channel isolation for crosstalk rejection
Accepts standard #18 AWG wire terminations
Compatibility & Integration The 7055 works with use with Keithley scanner mainframes including Models 7001, 7002, 705, and 706. Primary pairing is with the Model 7056 General-Purpose Scanner Card. The terminal card itself contains no switching channels; it functions exclusively as the external connection interface for compatible scanner cards within the system.
