INFORMATION
The Dry contact over lP Converter is an 8-way remote IO controller which supports 8-way DI/DO/AI, that is, digital input, relay output, analog input (including voltage and current). It also supports the serial port server function and connects to a third-party RS485 collector or controller over the RS485 port for remote control.
DI supports dry node and wet node, with optical coupling isolation. DO is the relay output, with 5A 250V AC or 5A 30V DC control capability. The first four AI inputs support 0 ~ 5V voltage input, and the last four support 4~20mA current input, and the ADC accuracy is 12 bits. The AI properties can be modified according to the needs of 5V voltage, 10V voltage, current type, resistance type and other properties.
lP Ethernet Converter characteristics
1. Supports eight DI/DO/AI channels and can be controlled remotely or locally.
2. AI supports 12-bit accuracy, and the data is adjusted to ensure accuracy.
3. It also supports the serial port server function to control external third-party RS485 devices over the network.
4. Support DI control DO function, using a pair of the converter through RS485 and Ethernet, can control each other, easy to use.
5. Support Modbus TCP, Modbus RTU, MQTT, JSON, HTTP and other communication modes.
6. Connect to various public clouds, send data in JSON format, and control delivery in JSON format.
7. Rich indicators: display DI, DO status, network status, data flow status, etc.
8. It can provide complete RS485 control instructions and Modbus RTU instructions, which is convenient for engineers to integrate development.
9. You can restore factory Settings with one click, including baud rate, station address, network configuration of communication module, etc.

Hardware description
Application:
l Building/access control/security control system;
l Industrial automation System;
l Internet of Things, remote meter reading, information collection, etc.
The dry contact IP converter (Ethernet interface) is used as an example. Figure shows the typical application connection. Connect the field input and output devices to the controller, and then connect the controller to the network via a network cable. Then the upper computer can send data to converter through Modbus TCP protocol to realize the query input device and control output device.
