The CTC100 Cryogenic Temperature Controller is configured to suit a wide range of research and industrial applications. The system consists of four sensor inputs, two powered and four analog voltage outputs, and up to six feedback control loops. Four general purpose analog and eight digital I/Os are available, along with auto tuning functions for setting PID parameters automatically. The CTC100 offers four temperature inputs that can read RTDs, thermistors, and diodes. Each temperature input channel has its own 24-bit ADC with eleven input ranges, and is equipped with its own independent excitation current source. Channel Setup Menu X Channel Setup Menu CTC100 Standard calibration curves for a variety of sensors are included, and custom calibration curves of up to 400 points each can be entered. Each sensor input has high and low level or rate-of-change alarms. Sensor inputs can be lowpass-filtered to reduce noise, and/or differenced with another channel. Powered and Analog Voltage Outputs The CTC100 has two heater outputs that can each deliver up to 100 W of power to a 25 Ω heater. In addition, four analog voltage I/O channels can be used to drive heaters with the help of an external amplifier. PID Feedback Control With up to six feedback control loops available, the CTC100 can provide precise temperature control of each of its heater outputs by continually adjusting the heater power. Any of the CTC100's channels can be selected as the input for each feedback loop. Feedback time constants can be adjusted between 200 ms and 10 hrs. Select Menu X Select Menu CTC100 Up to ten sets of PID parameters can be stored for each channel. Setpoints can be ramped at a fixed rate. Analog and Digital I/Os The CTC100 comes with four general-purpose ±10 V voltage I/O channels read by a 24-bit ADC . It also has eight digital I/O channels that can interact with user programs. Four 5 A relays can be used for process control. Three virtual channels, not connected to any physical input, allow calculated values (such as the difference between two channels, or a value calculated by a user program) to be displayed, graphed, and logged. Numeric and Graphical Display Numeric Display X Numeric Display CTC100 The CTC100's color LCD display can show any combination of temperature measurements and heater outputs on graphs or numeric displays. Up to eight channels can be plotted either on a single graph with a common Y axis, or on separate graphs with independent Y axis. Touchscreen operation makes the instrument versatile and easy to use. Up to 1 million readings per channel can be logged to the CTC100's internal memory. For longer-term storage , data can be logged to standard USB memory sticks or hard drives. Data logged to USB devices can be transferred to a computer by plugging the USB device into a PC. A Windows applications can be downloaded from SRS website to graph CTC100 log files. Computer Communications Each of the CTC100's front-panel controls has a corresponding text command that can be sent over USB, Ethernet, and either RS-232 or an optional GPIB interface.
