Build your own industrial current (4-20mA) to voltage (0-10VDC) converter/conditioner and save. 

 

Simply connect the board to to +/-15VDC. Apply 4-20mA to the input and read 0 to 10V on the output. 

 

Mount it, Just a two adjustments apply 4mA to the input and adjust the output to 0V via "Zero" P1 (multi-turn trimmer) apply 20mA to the input and adjust the output to 10V via "Span" P2 (multi-turn trimmer) and you're in business.

 

 

 

This industrial standard board can be configures via jumpers JP1 to JP3 to six different output voltage scales:

 

* Model A, 0 to +10VDC, 0 to -10VDC, -10 to +10VDC, +10 to -10VDC, -5 to +5VDC, +5 to -5VDC

 

* Model B, 0 to +5VDC, 0 to -5VDC, -5 to +5VDC, +5 to -5VDC, -2.5 to +2.5VDC, +2.5 to -2.5VDC

 

 

          

 

1. Zero calibration via multi-turn trimmer adjustment.

2. Span calibration via multi-turn trimmer adjustment.

4. Power input +/-15VDC

5. Current input 4-20mA (Other input current are available: 1-5mA, 10-50mA and 20-100mA)

6. Voltage Output 1 (See above table)

7. Voltage Output 2 (See above table)

 

Note: Voltage Output 1 is equal to Output 2. This additional output is frequently required when the signal divides into two sub systems. 

 

One can use our dual output transformers board together with our dual DC output power supply board (shown below) to get +/-15V DC 

 

 

 

 

Dual AC (VAC-1 and VAC-2) convert to -15VDC and +15VAC with common ground
