Four analog outputs with 14-bit resolution and +/-0.1% full-scale accuracy
Y301-0004 4-Channel RS485 Modbus Analog Output Module
4-Channel Analog Output Module
Y301-0004 provides four 14-bit analog outputs for HVAC and OEM controls, with 0-10 V or 4-20 mA options and Modbus RTU/ASCII over isolated RS485.
Key Features
0-10 V, 4-20 mA, and combo options; combo versions use per-channel mode jumpers
Opto-isolated RS485 or optional RS232 for Modbus RTU/ASCII control
Output settling time below 10 ms with a 12-30 VDC supply
Optional output retention restores the last analog value after reboot when enabled
