Stanford PTC10 Programmable Temperature Controller

Ideal for measuring temperature, controlling heaters and logging temperature data

Stanford Research Systems

The PTC10 programmable temperature controller is a modular system that can be configured to suit a wide range of applications. The system consists of the PTC10 controller and up to four I/O cards - two types of input cards for RTD's and thermocouples, and two types of output cards for controlling heaters. The I/O cards are ordered separately, and you can mix and match them in any way you wish.

 

Features:

  • Up to 16 input channels
  • Up to 4 PID feedback control channels
  • 50Hz PID sampling
  • 1mK resolution
  • Data logging on removable flash media
  • USB, Ethernet, RS232 interfaces (std)
  • GPIB interface (opt)

Input Cards

The PTC320 and PTC323 Thermistor/Diode/RTD readers can read a variety of resistive and diode temperature sensors. The PTC320 has a single input on a 6-pin circular DIN connector, while the PTC323 has two inputs on a 9-pin D-sub connector.

The PTC321 RTD reader has four inputs for 100 Ω platinum RTD sensors. Each channel has a four-wire input with its own 1 mA current source for sensor excitation. The current can be reversed with each reading to cancel out stray thermocouple EFMs.

The PTC330 four-channel thermocouple input card is factory configured to read either E, J, K, N or T type thermocouples. Each channel is electrically isolated allowing thermocouples to be attached to electrically-live equipment. An internal isothermal block, with its own RTD temperature sensor, provides highly accurate cold junction measurements.

 

Output Cards

The PTC420 AC output card is a heater driver that switches up to 5 A of 100 VAC to 240 VAC line current with a solid-state relay. The output power is controlled by switching the current on for some fraction of a 10 s cycle period and off for the remainder of the period. The PTC420 is intended to drive large heaters with response times of more than about 10 s. A PTC chassis can run up to two PTC420s at full power simultaneously.

The PTC430 and PTC431 DC output cards provide finer control for driving smaller, faster-responding heaters. The PTC430 delivers up to 1 A of current at 50 VDC, while the PTC431 delivers up to 2 A at 50 VDC.

The PTC440 TEC driver delivers ±5 A of current at ±12 VDC. This bipolar output card is optimized for driving thermoelectric coolers. It also includes a low resolution temperature sensor input that can read thermistors, RTDs, LM135, and AD590 sensors. For applications that require millikelvin resolution, a PTC320 card should be used with the PTC440.

A PTC chassis can run up to three PTC430s and/or PTC440s at full power simultaneously.
