The WJ225 series products can be applied in RS-485 bus industrial automation control systems, temperaturesignal measurement, monitoring, and control, etc. The product includes power isolation, signal isolation, linearization, A/D conversion, and RS-485 serialcommunication. Each serial port can connect up to 255 W1J25 series modules, and the communication methodadoptsASCII code communication protocol or MODBUS RTU communication protocol. The address and baud rate canbesetby code, and can be hung on the same RS-485 bus with control modules from other manufacturers for easy computerprogramming.The WJ225 signal isolation acquisition module can be used to measure 8 temperature signals. 1, Temperature signal input12 bit acquisition accuracy, 8 temperature signal inputs. Measure temperature range -200~600 degrees. Theproduct has been fully calibrated before leaving the factory. During use, users can also easily programandcalibratethemselves. 2, Communication ProtocolCommunication interface: 1 standard RS-485 or RS-232 communication interface. Communication Protocol: Supports two protocols, the character protocol defined by the command set andtheMODBUS RTU communication protocol. The module automatically recognizes communicationprotocols and can achieve network communication with various brands of PLCs, RTUs, or computermonitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) canbeset;The communication network can reach a maximum distance of 1200 meters and is connectedthroughtwisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication responsetimeless than 100mS. 3, anti-interferenceChecksums can be set as needed. There is a transient suppression diode inside the module, which caneffectivelysuppress various surge pulses, protect the module, and the internal digital filter can also effectively suppresspowerfrequency interference from the power grid.CertificationsQ: How to contact you?A: Please contact us via email or online customer service
