3.4.4 Analog restore output (AO) wiring

Figure 3-5 Receiver Wiring diagram

( The output is an active signal: constant current source output, the load resistance should be ≤500Ω)

(1) Analog input AI (Analog Input) related

1. Input source information: 0/4～20mA active analog signal, constant current source voltage should be ≥10V.

2. Error, accuracy, limit value: acquisition accuracy: ≤ ± 0.03mA; acquisition resolution: 0.001mA; input maximum

current Imax≤28mA, overcurrent may cause product damage.

3. The internal impedance of the product: 480 Ω

= 330 Ω

(current limiting protection resistance) + 150 Ω

(high-precision acquisition resistance).

(2) Related to analog output AO (Analog Output)

1. Output source information: 0/4～20mA active analog signal, constant current source output.

2. Error, precision, limit value, etc.: Output error: ≤±0.03mA. Output accuracy: 0.001mA. The load impedance should

be ≤500Ω, and active power supply should not be connected to avoid damage to the product.

3. Internal impedance of the product: constant current source voltage: 24V. Constant current source internal resistance:

500Ω.
