Product description
MR-DO16-D is mainly composed of power supply circuit, isolated switch output circuit, isolated RS485 communication circuit and MCU. Switch 2 groups separated (drain) output channels, each of the 8 channel, 16 channel; high speed C51 processing chip, has strong data processing ability; watchdog circuit design, can automatically reset when the accident occurred at MR-DO16-D, ESD, overvoltage and overcurrent protection system design, to ensure the long-term stable and reliable operation.
At the same time, for industrial applications, the MR-DO16-D is designed with RS485 communication interface isolation, to avoid affecting the industrial field signal to MR-DO16-D communication interface; communication timeout detection function; Modbus standard RTU communication protocol, so that users can more easily realize the integration and application of SCADA software, HMI equipment and support Modbus RTU protocol PLC equipment and system the. Moreover, we provide free protocol and sample code, so that your two development more flexible, simple and efficient.
Product features
1, 16 channel leakage switch signal output;
2, the output of the switch is completely isolated from the system;
3, Modbus RTU communication protocol, support 1, 3, 5, 6, 15, 16 function code;
