Keithley KPCI-3130

The Keithley KPCI-3130 is a PCI-bus data acquisition card engineered for precision analog signal sourcing and industrial digital control in automated test and machine automation systems. It delivers 8 channels of 20-bit analog output with ±10V range and 32 user-configurable digital I/O lines, addressing demanding measurement requirements in semiconductor testing, product validation, simulation, and servo control applications.

– Technical Specifications

Analog Outputs
• 8 industrial-grade channels at 20-bit resolution (19.1µV/count)
• Voltage range: ±10V per channel
• Accuracy: ±700µV ± 0.008% of setting at 25°C ±1°C
• Temperature coefficient: 150µV/°C; ±20ppm setting/°C
• Output current: 20mA per channel (source or sink)
• Settling time: 15ms to 600µV typical for ±9.5V transients
• Four-quadrant source/sink operation with automatic fault detection on 4-wire configuration
• Differential remote sensing eliminates lead-line losses by measuring actual voltage at the DUT

Digital I/O
• 32 high-current lines, user-configurable
• Designed for solenoid, valve, actuator, and solid-state relay control

Interface
• Analog output: 36-pin connector
• Digital I/O: 36-pin connector with 50-pin KPCI-PIO-96 compatible pinout
• PCI-bus with high-speed data transfer

– Key Features

The single ±10V range eliminates glitching artifacts inherent in multi-range output boards. Remote sense capability with differential measurement maintains accuracy across cable runs by compensating for lead-line losses—unused sense lines require termination (Sense HI to Output, Sense LO to GND/Return). The card supports four-quadrant operation, enabling both power delivery and power dissipation in test scenarios.

– Typical Applications

Semiconductor machine control, product testing, simulation testing, servo control, and automated test equipment platforms requiring synchronized analog sourcing and discrete I/O switching.
