1. Overview ​

The Y301-006/008/00G series is a family of multi-channel analog input concentrators based on the DAM1600AI-YD hardware platform. The modules acquire 4-20 mA or 0-10 V signals over a Modbus RTU/ASCII link and transfer normalized values to PLCs, SCADA systems, or edge controllers.

6. Wiring Guidelines ​

6.1 Power Connection ​

  • Use 18-22 AWG wiring for the 7-30 VDC supply
  • Add a 500 mA fuse for overcurrent protection
  • Verify correct polarity before power-on

6.2 Sensor Connection ​

Voltage mode (0-10 V):

  • Connect the sensor positive lead to AI+ and the negative lead to AI-
  • Suitable for 3-wire voltage sensors

Current mode (4-20 mA):

  • Wire the sensor in series with the AI+ and AI- current loop
  • Suitable for 2-wire or 4-wire current transmitters

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
