Selection Samples:

Part No.:WJ80-A4-RJ45     (means 8 channels 4-20mA input,ouput is RJ45 interface)

Part No.:WJ28-U1-RJ45    (means 8 channels 0-5V input,output is RJ45 interface)

Function Description:

    WJ80 remote I/O module can be used to measure eight channels analog signal and four channels switching signal, and there are two channels switching output and one channel 0~4.8V voltage signal output.

1. Analog signal input

16 bits,8 analog signal input. All the products signal input ranges have been calibrated after leaving the factory. When used, users can also program and calibrate by themselves easily. For specific current or voltage input range, please refer to product selection.

2. Switching signal input and output, one channel 0~4.8V voltage signal output

8-channel switch signal input, can be connected to dry contact and wet contact, please refer to the wiring diagram for details. 8-channel switch signal output open collector output.

One channel 0~4.8V voltage signal output can be used for analog signal control.

3. Communication protocol

Communication interface: RJ-45 network interface. The two indicators on the network port position, the Link light (green light) is on after the network cable is plugged in, and the Data light (yellow light) will flash from time to time.

Communication protocol: Realize industrial Ethernet data exchange by using MODBUS TCP protocol. The control module can also be accessed directly via the web page.

Network cache: 16K Byte (received and sent)

Communication response time: less than 100mS.

3. Anti-jamming

Module has a transient suppression diode inside, which can effectively suppress various surge pulses and protect the module
