SpecificationProduct SelectionWJ70 -Communication Interface485: output is RS-485 interface 232: output is RS-232 interfaceSample 1: part No.: WJ70-232 means output is RS-232 interfaceSample 2: part No.: WJ70-485 means output is RS-485 interfaceCompany ProfileShenzhen Weijunrui Technology Co., LtdSince: 2011Specialty: The company's main products include analog acquisition modules, signal isolators/conversion modules, and signal transmittersCapacity: Produce 10000 per monthAdvanced Features:Switching to TCP/network/remote IO module, Modbus RTU to TCP, RS232/485 to Ethernet, analog signal (current/voltage/thermistor/frequency/displacement/speed/pulse) isolation transmitter, mV differential signal amplifier, isolation amplifier, micro power DC-DC module power supply, etcGlobal ShowroomsFactory CapabilitiesWJ70 General parameters: (typical @ +25 ℃, Vs is 24VDC)Input type: switch input,4 channels (DI0~DI3) Low level: input <1V High level: input 4 ~30VInput Resistance: 3KOutput type:C type relay signal output,4 channels (DO0~DO3) .Normally open/normally closed and public Contact load capacity: 1A 125VAC or 2A 30VDC . Contact form: 2Z Maximum switching voltage: 240VAC / 120VDC Maximum switching current: 2ACommunication: RS-485 protocol or RS-232 standard characters protocols and MODBUS RTU communication protocol Baud Rate (2400,4800,9600,19200,38400 bps) can be selected via softwareAddress (0 to 255) can be selected via softwareCommunication Response Time: 100 ms maximumPower Supply: +8 ~ 32VDC wide range power supply, internal anti-reverse and over-voltage protection circuitPower Loss: less than 0.5WOperating Temperature: - 45 ~ +85℃Humidity: 10 ~ 90% (no condensation)Storage Temperature: - 45 ~ +85℃Storage Humidity: 10 ~ 95% (no condensation)Isolation Voltage: Isolation between each input,isolation between each output. Input/output/power supply: three-isolation(1500VAC)Dimensions: 120 mm x 70 mm x 43mm WJ70 products are according to industry standard design, non-isolation between signal input / output, highanti-interference ability and reliability. Operating temperature range is - 45 ~ +85 °C.Function Description:WJ70 remote I/O module can be used to measure 4 channels switching signal, and 4 channels relay signaloutput.4-channel C type relay signal output,there are often open and close nodes.1. Switch signal input and output4 channels switching signal Input, can connect dry contact and wet contact.Details refer to the wiring diagram.2. Communication protocolCommunication Interface: one channel standard RS-485 communication interface, or one standard RS-232communication interface, specify when ordering.Communication Protocols: supports two protocols, characters protocol of the command set defined and MODBUSRTU communication protocol. Can be programmed using the kind of communication protocol, can beachieved with PLC, RTU of many Brands or computer monitoring system for network communication.Data Format: 10 Bits. 1 start bit,8 data bits,1 stop bit.Address: (0 to 255) and baud rate (2400,4800,9600,19200,38400 bps) can be set, the most long-distance aboutcommunication networks is up to 1200 meters, through the twisted-pair shielded cable.Communication interface of high anti-jamming design, ± 15KV ESD protection, communication response time is lessthan 100mS.3. Anti-jammingAccording to need to set the checksum. Module internal has transient suppression diodes, can inhibit a variety ofsurge pulse, protection module, and internal digital filter can also be well suppressed from the grid frequencyinterference.
