Features At A Glance
Modbus RTU Analog Output 8CH is an industrial standard analog output module, supports 8-ch simultaneous output. Adopts Modbus RTU protocol with built-in protection circuits such as power isolation, magnetical isolation, resettable fuse, and TVS.
- Configurable device address (1~255), multi devices can be cascaded on RS485 bus
- Onboard voltage regulator, supports 7~36V wide range power supply
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference
- Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic
- 12-bit DA conversion, using high-precision resistors for more accurate output data
- Onboard watchdog, for stable output without crashing
- Rail-mount case design, support stacking combination, easy to install and safer to use
- 3x LEDs for indicating the MCU status and signal transceiving status

Primary Function
Supports Sending Modbus RTU Protocol Commands Via RS485 And Outputing Data To 0~10V Or 0~20mA Sensor
Industrial Grade Isolated Protection
Onboard power and signal dual isolation for RS485 communication, provides stable isolation voltage, features high reliability and strong anti-interference performance. Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable current and voltage output, provides over-current and over-voltage proof, improves shock-proof performance, suitable for industrial environments with high requirement.
