Temperature Controllers PTC10 — Programmable temperature controller PTC10 Temperature Controller · Up to 16 input channels · Up to 6 PID feedback control channels · 50 Hz PID sampling · 1 mK resolution · Data logging on removable flash media · USB, Ethernet, RS-232 interfaces (std.) · GPIB interface (opt.) 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 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. Stanford Research Systems 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

PTC10 Programmable Temperature Controller Standard calibration curves are included for popular sensor types. Custom calibration curves with up to 200 points each can also be applied to any input; the curves are stored on a removable USB memory device and are loaded by simply plugging the device into the PTC10. Sensor calibration can also be adjusted by entering an offset and gain from the front panel. 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...

Multi-Purpose Ports The PTC10 has four configurable general-purpose analog I/O channels, each of which can be used either as a 24-bit, ±10V input or a 16-bit, ±10V output. The PTC10 also has eight bidirectional digital I/O lines that can interact with macros, and four relays that can be tripped by alarms, remote commands, macros, or from the front panel. The PTC10’s analog I/O channels can be used as feedback inputs, and custom calibration curves can be applied to convert their voltage readings into temperature, pressure, etc. values. If configured as an output, each analog I/O channel has its...
