You can select 24V output or 24V and 1.1Ω resistor
series connection output through the jumper J11. By
default, 24V output is selected in factory.
24V reference ground
1. Resolution: 1° C
2. Range: -20° C–150° C
3. Detection precision: 3° C
1. Input range: current/voltage is optional, 4–
20mA/2–10V corresponds to 0–1.6MPa; of which P1
is switched via the jumper J8, and the default is input
current signal.
2. Input impedance: 30kΩ during voltage input;
500Ω during current input
3. Resolution: 5mV (minimum value)
4. Error: ± 1%, 25° C
1. Internal impedance: 3.3kΩ
2. 12–30V voltage input is acceptable
3. Max. input frequency: 1kHz
You can select internal power (NPN mode) or
external power (PNP mode) through the jumper J9.
The default is internal power (NPN mode).
1. Internal impedance: 3.3kΩ
2. 12–30V voltage input is acceptable
3. Max. input frequency: 1kHz
This channel circuit uses internal power (NPN
mode).
External PTC temperature switch signal input, PTC
resistance acts at 2.3kΩ.
1. Output range: 0–10V voltage or 0–20mA current;
voltage or current output is switched via the jumper
J2. The default is current type.
2. Error: ± 1%, 25° C
