UN 231-8PD22-0XA0/UN 231-8PH22-0XA0

200 Temperature Modules
4TC & 8TC PID products integrate advanced PID control algorithm, and integration for large lag, emperature and temperature in the mutual interference temperature reaches the set temperature simultaneously. For low speed, large delay temperature control field optimization PID control algorithm to solve the problem of slow temperature control, heating speed and temperature overshoot
4/8 channel thermocouple temperature measurement, 16-bit resolution
Signal optocoupler isolation, stable performance, easy to use power isolation protection
Integrated advanced PID temperature control algorithm, multi-temperature zone temperature control. Dramatically reduce equipment commissioning time
Applicable temperature range: room temperature ~ 500 ° C (depending on the environment and different).
Heating overshoot ≤3 ° C, steady state error ≤1 ° C (varies depending on environment)

Targeted industries include extrusion, injection molding, large-scale textile machinery and other multi-temperature control industries
