DIMENSION

Unit:mm

OUTPUT CHARACTERISTICS

PT100
T=0℃,R=100Ω, T≈100+0.385*Δt, Temperature and resistance is direct ratio relation.
4-20mA
T=((Iout-4)/(20-4))*(Range_max-Range_min)+Range_min
0-5V
T=(Vout/5)*(Range_max-Range_min)+Range_min
RS485
If the transmission distance is over 100m, please add a 120Ω terminal matching resistances on the front end and back end of bus interface respectively.See the modbus communication protocol specification.
