The Autonics TC4SP-N4R device features a DIN size of W48×H48mm with a 4-digit 7-segment LED display. It supports multiple control methods including ON/OFF, P, PI, PD, and PID, and input options cover Thermocouple types K (CA), J (IC), L (IC) as well as RTD options such as DPt100Ω and Cu50Ω. A sampling cycle of 100 ms ensures timely updates. The control output can be configured as a Relay (250VAC, 3A) or SSR drive (12VDC specialstring) with ON/OFF, phase, or cycle control modes. Power is supplied by 100-240VAC at 50/60 Hz. Hysteresis (adjustable sensitivity) ranges from 1 to 100°C/°F (0.1 to 50.0°C/°F) and is variable. The Proportional band ranges from 0.1 to 999.9°C/°F, the Integral time from 0 to 9999 seconds, and the Derivative time from 0 to 9999 seconds, with a Control period from 0.5 to 120.0 seconds. Manual reset ranges from 0.0 to 100.0%. The operating ambient temperature is -10 to 50°C, with storage from -20 to 60°C, and ambient humidity ranges from 35 to 85% RH for both operation and storage. The insulation type is double insulation or reinforced insulation (mark: specialstring), with dielectric strength between the measuring input part and the power part specified as AC power 2 kV and AC/DC power 1 kV.
