1. Overview ​

The Y331 fully isolated multi-range analog input modules belong to the YenGear Serial I/O Modules family. They provide 2, 4, 6, or 8 analog inputs for DC voltage and current acquisition.

Each input channel is isolated from the other input channels. Signal options cover millivolt, voltage, milliamp, and ampere ranges.


2. Ordering Information ​

2.1 Model Configuration ​

The four positions after Y331- follow DI / DO / AI / AO. Retain all four positions, including the final zero. Y331-0080 means 0 DI, 0 DO, 8 AI, and 0 AO.

5.1 Terminal Overview ​

GroupTerminals / Function
PowerDC+ / DC-: supply positive / negative, 6-36 VDC
Voltage inputV+ / V-: positive / negative for each channel
Current inputI+ / I-: positive / negative for each channel
CommunicationA/H / B/L: use the interface-specific terminal drawing for pin assignments
EarthPE: follow the model-specific wiring drawing
Hardware settingsDIP switches for address and baud-rate settings
IndicatorsPWR power indicator; RUN, BAT, ERR, and numbered channel indicators

5.2 Wiring Guidelines ​

  • Use the voltage or current terminals that match the ordered range.
  • Keep each channel's input pair separate to preserve channel isolation.
  • Follow the model-specific power, earth, and communication terminal labels.

See the Technical Manual for RS485 commissioning and configuration.
