CONVERTER – VXMA420 - Industrial voltage to current converter (transducer) with Zero and Span Adjustments.

This OEM board offers effective, state-of-the-art, reliable linear control of HVAC 4-20 dampers and valves. 

The CONVERTER-VXMA420 voltage to current converter is a signal control (Proportional) voltage to current transducer board for HVAC (Heating, Ventilation and Air Conditioning), electro-hydraulic and servo electronics; actuator, dampers, bleed pilot valve, globe valves, butterfly valves, plug valves and more.

The CONVERTER-VXMA420 board is designed to perform voltage to current conversion (4 to 20 mA transducer) with maximum linearity. If used properly, it will eliminate the need for an expensive board, which would otherwise be needed to carry out the same tasks.

Shown above configured for 0-5VDC inputs signals convert to 4-20mA output current

The CONVERTER-VXMA420  is easy to install, setup, and operate. If you want to do professional remote voltage measurement related functions, The CONVERTER-VXMA420 offers the features you need. It can be mounted easily via two 0.125" mounting holes using 4-40 screws.

Simply connect the board to 24VDC or 24VAC connect your voltage source 0-10V DC to the input and our board will convert it to 4-20mA.

The CONVERTER – VMA420 transducer board is an accurate, linear, and an efficient way to convert industrial standards voltage (input DC voltage models) 0 to 5V, 0 to 10V, or 0 to 24V into industrial standards (output current float on 16-20V DC) current 4 to 20mA signals.... See below table "voltage to current industrial standard configuration models".

Note: Using industrial standard 249 Ohms 1% resistor on the meter side (deferential input preferred) will produce 1 to 5V DC for 4 to 20mA. Using 499 Ohms 1% on the remote side will produce 2 to 10V DC.

1. Power 24V AC or DC.

2. 0-5V or 0-10V or 0-24V DC input voltage signals.

3. 4-20mA output current.

4. Input/output multi-turn trimmer Span adjustment.

5. Input to output multi-turn trimmer Zero adjustment.

6. LED power indicator.
