Analog signal input 12 bit acquisition accuracy, one analog signal input. All signal input ranges have been calibrated before the product leaves the factory. During use, users can also easily program and calibrate themselves. Please refer to the product selection for specific current or voltage input range. 2. Communication Protocol Communication interface: RJ-45 network interface. The two indicator lights at the network port position, the Link light (green light) stays on and the Data light (yellow light) stays on after the network cable is plugged in. Communication protocol: MODBUS TCP protocol is adopted to achieve industrial Ethernet data exchange. It can also communicate with modules through TCP sockets. Network cache: 2K bytes (for both sending and receiving) Communication response time: less than 10mS. 3. Anti interference There is a transient suppression diode inside the module, which can effectively suppress various surge pulses and protect the moduleWJ181 General Parameters: (Typical @+25 ℃, Vs is 24VDC) Input type: current input/voltage input Accuracy: 0.1% Temperature drift: ± 50 ppm/℃ (± 100 ppm/℃, maximum) Input resistance: 150 Ω (4-20mA/0-20mA/0- ± 20mA current input) 300 Ω (0-10mA/0- ± 10mA current input) 1.5K Ω (0-1mA/0- ± 1mA current input) Greater than 200K (5V/10V voltage input) Greater than 1M Ω (input voltage below 2.5V) Bandwidth:-3 dB 10 Hz Conversion rate: 16FPS (factory default value, users can modify the conversion rate on the webpage.) You can set the AD conversion rate to 2SPS, 4SPS, 8SPS, 16SPS, 32SPS, 50SPS, 80SPS, 100SPS by sending commands Common moderejection (CMR): 120 dB (1k Ω Source Imbalance @ 50/60 Hz) Normal mode suppression (NMR): 60 dB (1k Ω Source Imbalance @ 50/60 Hz) Input protection: overvoltage protection, overcurrent protection Communication: MODBUS TCP communication protocol or TCP socket character protocol or MQTT protocol Webpage: Supports web access module and web page setting module parameters. Interface: RJ-45 network interface. Communication response time: 10 ms maximum Product Overview: WJ181 The WJ181 product is an IoT and industrial Ethernet acquisition module that enables transparent data exchange between sensors and networks. The analog data from sensors can be forwarded to the network The WJ181 series products include power conditioning, analog acquisition, and RJ-45 network interface communication. The communication method adopts MODBUS TCP protocol. TCP is a transport layer based protocol that is widely used and a reliable connection oriented protocol. Users can directly set module IP addresses, subnet masks, etc. on the webpage. Can be used for monitoring and controlling the operation of sensor devices. The WJ181 series products are intelligent monitoring and control systems based on microcontrollers, where user set module IP addresses, subnet masks, and other configuration information are stored in non-volatile memory EEPROM. The WJ181 series products are designed and manufactured according to industrial standards, with strong anti-interference ability and high reliability. The working temperature range is-45 ℃ to+80 ℃.FAQQ: How to contact you?A: Please contact us via email or online customer service
