Model number: CT401BFK01-VM*N 

96*48mm panel mounted; K thermocouple input; SSR output for temp. control; Relay contact output for time control;No alarm function.


Detail Specifications:


Model number: TREX-CT401B

Basic error: ≤±0.5% F.S. ; ±1 digit ; ±0.25%F.S. ±1 digit

Cold junction compensation error: ≤± 2.0°C

Sampling cycle: 1 second

Control cycle: 1~100 second adjustable for main output

Input signal: K type thermocouple

Main output: 0~12VDC to drive SSR, maximum output current 30mA

Relay contact output( time counting ): 5A/250VAC(resistive load)

Work voltage: 100~240VAC, 50/60Hz

Work condition: temperature 0~50 °C, humidity <85% no caustic or magnetic field interference


Action Logic (important about function):


   CT401B has temperature controlling and time counting functions two in one.   


   For temperature controlling: PID theory with auto tune function for temperature controlling.  Output signal 0~12VDC voltage to drive SSR. Two LED windows displays Current value and setting value  in Centigrade. 


   For time counting: There are two time trigger modes selectable:  Start to count when power on,Or Start to count when trigger signal detected. Preserve two  Binding Posts for time start trigger.  User can connect a switch on PIN No.4 and No.5 to trigger time counting. When controller enters time counting mode, Lower LED window display past time ( Count up to set point).
