Temperature controller with touchscreen PTC10

programmablePID

Introducing the PTC10 Programmable Temperature Controller from SRS—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. 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 EMFs. 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
