This unit
The Keithley 7154 High Voltage Scanner Card is a field-installable switching component for automated high-voltage test and measurement systems. It routes high-voltage signals within Keithley scanner mainframes, enabling precision switching in demanding test environments where complex signal paths and voltage isolation are critical. The card delivers 10 independent channels of 2-pole relay switching with fused protection on each pole, supporting peak voltages to 1100V and carrying currents to 1.0A RMS.

Storage Temperature: -25° to +65°C
Dimensions: 32mm H × 114mm W × 272mm L
Weight: 0.34 kg
Key Features
Double-pole, normally open relays with individual fused inputs on each pole
User-selectable shield or driven guard configuration
Common guard input applicable to all channels; isolation by jumper removal
Multiple switched guards achievable via Low input terminal connection
Fast relay actuation supports high-speed test sequences
Excellent contact potential minimizes measurement errors in precision circuits
Typical Applications High-voltage signal routing, automated switching matrices for power testing, precision measurement multiplexing, and complex test routines requiring galvanic isolation and high voltage capability.
Compatibility & Integration Designed for Keithley scanner mainframes (Models 705, 706). Card operates in 2-pole mode when used alone or with other 10-channel cards. Field installation within compatible mainframe chassis.
