Industrial 8-Ch Analog Output Module, 12-bit DA Conversion, Supports 8-ch simultaneous Voltage or Current Output, DC 7~36V Wide Voltage Power Supply, Modbus RTU Protocol, Rail-Mount Support.
Features:
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, magnetic 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 magnetic isolation, allows signal isolation, high reliability, strong anti-interference
- Onboard resettable fuse and TVS (Transient Voltage Suppressor) , effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightning proof & 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, lightning proof & 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.
