4–20 mA Pulsed Signal Transmitter
CODE 06750005
The transmitter converts the fertilizer or acid injection pulses into
4-20 mA outputs to control injectors with a frequency inverter.
Useful in controllers that does not have 4-20mA analogue outputs;
for example, the Agrónic 2500 or the Agrónic 5500.
It offers the following benefits:
• Reading and conversion of up to three different pulsed signals (3 inputs) to 3 4-20 mA outputs.
