Lake Shore DRC-93CA

The Lake Shore DRC-93CA is a microprocessor-based temperature controller engineered for precise cryogenic temperature management. It delivers real-time analog control using three-term (PID) circuitry to maintain user-defined setpoints with high stability and accuracy. The controller supports internal programming with up to 99 steps and accommodates multiple sensor types, making it adaptable to diverse low-temperature applications. ## Technical Specifications Control Architecture • Three-term (PID) real-time analog control • Setpoint management via analog voltage comparison with actual sensor signal • Up to 1 Ampere heating output into a 50 Ohm resistive heater • Internal programming capacity: 99 program steps Sensor Input & Measurement • Two sensor input card slots • Two five-digit sensor displays with resolution of 0.01 K above 100 K and 0.001 K below 100 K • 16-bit analog-to-digital converter with 100 microvolt resolution (full scale dependent on card configuration) • Compatible with silicon sensors (9210-3 or 9220-3) and Gallium-Aluminum diode sensors • Optional 8229 Scanner Conversion Card extends capability to 6 sensors • Display modes: K, °C, °F, or sensor units (volts, ohms, nanofarads) Physical & Integration • Rack-mountable chassis configuration • Input card compatibility: 9102 card configured as 9102-3 or 9102-6 • Math functions available ## Key Features • True analog control with PID tuning for stable temperature maintenance • Dual five-digit displays for simultaneous sensor monitoring • Flexible sensor compatibility spanning silicon and diode technologies • Expandable architecture supporting up to 6 sensors via optional scanner card • High-resolution measurement: sub-millikelvin precision below 100 K • Multiple temperature unit display options for operational flexibility ## Compatibility & Integration The DRC-93CA represents an upgrade to the DRC-93C and integrates with Lake Shore silicon and Gallium-Aluminum diode sensor families. The modular input card design permits configuration flexibility through the 9102 series, while the optional 8229 Scanner Conversion Card enables multi-sensor applications without requiring additional controller hardware.
