It is a Voltage Transmitter/Power Supply Module, Power supply: DC 7~36V (if the output needs to be 10V, the input must be over 12V), In the process of signal transmission circuit voltage signal will increase transmission distance becomes weak, the transmission can be avoided using weak electric current signal. suitable for in the industrial instrument for long distance signal transmission.

• 1. Power supply: DC 7~36V (if the output needs to be 10V, the input must be over 12V)
• 2. After power on, the D2 indicator should be on. Otherwise, please check the wiring.
• 3. The product has reverse polarity protection.
• 4. When the current input is at minimum (0mA or 4mA), adjust the Zero potentiometer to make the voltage output to be the minimum value (0.0V or others).
• 5. When the current input is at maximum (20mA), adjust the Span potentiometer to make the voltage output to be the maximum value (3.3V or 5V or 10V; the output can be as low as 2.5V when the current input is within 4 -20mA).

• ON: jumper cap buckles on the two jumper pins
• OFF: two jumper pins without the jumper cap
• 4 -20mA: 0 -2.5V range:   pin 1, 2 ON    pin 3, 4 ON
• 0 -3.3V range:   pin 1, 2 OFF   pin 3, 4 OFF
• 0 -5.0V range:   pin 1, 2 ON    pin 3, 4 ON
• 0 -10.0V range:  pin 1, 2 ON    pin 3, 4 OFF
• 0 -20mA: 0 -3.3V range:   pin 1, 2 ON    pin 3, 4 ON
• 0 -5.0V range:   pin 1, 2 ON    pin 3, 4 ON
• 0 -10.0V range:  pin 1, 2 ON    pin 3, 4 OFF

• 1 x Voltage Transmitter
