In the Internet of Things environment or automation control environment, many devices need to work 24h uninterruptedly, which involves the power failure alarm function; for example, in the building automation project there is a branch circuit in the power grid fan power failure to stop working, this situation once appeared then you need to manually carry out one by one troubleshooting, the process is time-consuming and laborious, in this scenario with the addition of the WE-IH16RM AC power monitoring module can be Quickly find the location of faulty circuits; this module is suitable for a variety of fields: fire, warehousing, street lighting, medical equipment and other scenarios.
WE-IH16RM is a 16 channel AC input RS485 data acquisition module with AC input range of 90~275V. The AC input range is from AC90 to 275 V. It adopts the standard Modbus RTU slave communication protocol, and can be used for remote data acquisition via RS485 bus. This product has good expansion performance and is easy to use. WE-IH16RM supports MODBUS multiple function codes and can support up to 250 devices on the RS485 bus. Of course, the number of devices on the bus is also related to the RS485 transceiver device of the PC. In order to support 250 devices on the system, the load of the RS485 transceiver device of the PC must be greater than 250.
