This link is special for:
1. Measuring range: the one you choose
2. Output signal: 2 wires 4~20mA, OR 4 wires 4-20mA 2 relays (4 wires with RS485 )
3. Power supply: DC24V
Notes:
if you choose only 4-20mA output, is 2 wires output,product wiring as this :
if you choose only 4-20mA + 2relays output, is 4 wire output,product wiring as this :
What we can make:
1. Available measuring range: any range within0~15 metres
2. Available output signal:4~20mA, 2 relays, RS485
3. Available power supply:DC24V, AC220V
