Best Fit
- Multi-zone building automation and equipment control.
- Large telemetry panels that need 16 digital points in one module.
- PLC or gateway expansion where RS485 Modbus RTU is already used.
Key Features
- 8 dry/wet contact DI channels plus 8 SPDT relay outputs.
- Independent indicators for all 16 channels plus system status.
- Up to 16 local rules for follow, pulse, timer, logic, and schedule modes.
- Software Modbus address 1-255 plus 5-bit DIP offset for panel deployments.
- 5 to 36 VDC input, -40 to 85 C operation, hardware watchdog, Reload button.
Before Ordering
Use Y301-880 when the project needs many digital points but no analog input. For analog sensing, compare it with Y301-444 or the dedicated Y301 analog input modules.
