Carlo Gavazzi Duplex fieldbus User Manual for Dual Channel Input Module G50102206
Key Features
Number of channels: 2 independent inputs (channel 1+channel 2)
Input type (each channel can be independently configured):
Voltage mode: 0-10V DC
Current mode: 0/4-20mA (switched by jumper)
Communication protocol: RS-485 Modbus RTU (default baud rate 9600/19200/38400 bps, addresses 1-247)
Isolation level: 1500V AC isolation between input/communication/power supply
Wiring diagram (terminal definition)
Terminal number function description
1. 2 DC 24V power supply 1:+24V (18-30V DC), 2: GND
3-6 channel 1 signal 3: Ch1+, 4: Ch1-, 5: Shield (grounded)
7-10 channel 2 signal 7: Ch2+, 8: Ch2-, 9: Shield
11-12 RS-485 communication 11: A+, 12: B-
⚠️ Attention: The shielded wire must be grounded to suppress interference!
Jumper configuration (independent for each channel)
Jumper group position function
JP1 ON/OFF Ch1 signal type: ON=voltage, OFF=current
JP2 ON/OFF Ch2 signal type: ON=voltage, OFF=current
JP3 ON terminal resistor (only enabled for bus terminal module)
Modbus Register Mapping
Function Description of Register Address Data Type
30001 UINT16 channel 1 raw value (0-65535)
30002 Float Channel 1 scaled engineering value (calibration required)
30003 UINT 16 channel 2 raw value
30004 Float channel 2 scaled engineering value
Conversion formula (taking current mode as an example):
Actual value=(raw value/65535) × 20mA × range factor
Calibration steps (independent for each channel)
Zero calibration: Input 4mA (current mode) or 0V (voltage mode) → Read registers 30001 (Ch1)/30003 (Ch2) → Record as AD_Low
Full range calibration: Input 20mA or 10V → Record as AD-High
Set linear conversion in PLC:
plaintext
Engineering value=(current AD value - AD_Low) × (range upper limit - range lower limit)/(AD-High - AD_Low)+range lower limit
LED status diagnosis
Meaning of LED status
PWR green constant light power supply is normal
COM yellow flashing data communication
ERR red 2 times/second module internal error (restart check)
Red constant light communication timeout/address conflict
Troubleshooting
Phenomenon solution
Single channel no data check jumper settings → Measure input terminal voltage/current → Verify sensor power supply
Unstable communication, enable terminal resistor JP3 → check A+/B polarity → reduce baud rate
Data jump signal line with magnetic ring → single point grounding of shielding layer → away from frequency converter cable
