6. Wiring Guidelines ​

6.1 Power Connection ​

  • Use 18-22 AWG wiring for the 12-30 VDC supply
  • Add a 1 A fuse for overcurrent protection
  • Verify correct polarity before power-on

6.2 Output Connection ​

Voltage mode (0-10 V):

  • Connect the load positive terminal to AO+ and the negative terminal to AO-
  • Load impedance should be greater than 2 kohm for best accuracy

Current mode (4-20 mA):

  • Wire the load in series with the output loop
  • Total loop impedance should be less than 600 ohm
  • Suitable for 2-wire or 4-wire instruments

6.3 Communication Connection ​

RS485:

  • Use shielded twisted pair
  • Add 120 ohm termination resistors at both ends of the bus
  • Connect A to A, B to B, and GND to GND across all devices

RS232:

  • Connect directly to a DTE device
  • Maximum cable length is 15 m
