Input Cards

The PTC320 Thermistor/Diode/RTD reader has a single input that can read a variety of resistive and diode temperature sensors including thermistors, RTDs, cryogenic diodes, and ruthenium oxide sensors.


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 DC output card delivers up to 1 A of current at 50 VDC, or up to 2 A at 20 VDC. Its unipolar output provides finer control for driving smaller, faster responding heaters.


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 temperature sensor input that can read thermistors, RTDs, LM135, and AD590 sensors.

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

The PTC10 Programmable Temperature Controller from SRS is the ideal instrument for measuring temperature, controlling heaters, and logging temperature data.


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 RTDs and thermocouples, and two types of output cards for driving heaters.


The I/O cards are ordered separately, and you can mix and match them in any way you wish.
