General Description

It is of modular structure and a safety explosion-proof card-mounted instrument. It change the value of thermal resistance to 4 ~ 20mA DC (or 1 ~ 5V DC) isolated signal output, which has linear relationship with temperature.

Main technical parameters

Input: standard thermal resistance (three-wire)
Output: 4 ~ 20mA DC (or 1 ~ 5V DC)
Output Resistance: 250Ω (when output is 1 ~ 5V DC);

  1. 500kΩ (4 ~ 20mA DC output)

Load resistance: ≤ 350Ω (when output is 4 ~ 20 mA DC)
Input pin effects on resistance: resistance of each line≤5Ω (three-wire equivalent)
Accuracy: when the range ≥ 50 ℃, ± 0.2%;
When the range<50℃, ± 0.5%
Common-mode interference: <5mV when 50Hz
Response time: <1s
Isolation: input, output, power supply isolated from each other
Zero adjustment: ZERO potentiometer
Adjustment range: SPAN potentiometer
Power: 24VDC ± 10%
Power consumption: <1.5W
Ambient temperature: 0 ~ 50 ℃
Atmospheric pressure: 86 ~ 110Kpa
Relative temperature: <90% RH (no condensation)
Insulation resistance: ≥ 100MΩ among current, input and output terminals
Dielectric strength: 1000V DC / min among power supply, input and output terminals
Weight: about 150g
Maintenance: under the condition of wiring, the instrument can be replaced
