Isolated Digial To Current Converter PCI5I

The PCI5I module is optically isolated digital to analog converter, changing the logical combination of five digital inputs to one current signal 0...20mA or 4...20mA. Thanks to an ultra-precision electronic components, output current is stable in time and temperature, and accurately reproduces input states.

Giving the voltage U1...5 to optically isolated inputs, the voltage output is generated by the formulas:
Isolated Digial To Current Converter PCI5I
Price: 65.5 €
For 0...20mA version:

For 4...20mA version:

U1..5 < 3V AC/DC → DI1...5 = 0
U1..5 > 7V AC/DC → DI1...5 = 1

LED diodes indicate states of digital inputs.
