Overview

The AD/DA analog signal data collector product realizes signal acquisition between sensors and hosts, used to detect analog signals or control remote devices. Through software configuration, it can be used for various sensor types, including analog signal input, analog signal output, and digital signal input/output (I/O)

Product Details

ISO4021 seriesThe product implements signal acquisition between sensors and hosts to detect analog signals or control remote devices. Through software configuration, it can be used for various sensor types, including analog signal input, analog signal output, and digital signal input/output (I/O). ISO 4021 series products can be applied to industrial automation control systems with RS-232/485 bus, 4-20mA/0-5VAD/DA Analog Signal Data CollectorSignal measurement, monitoring and control, measurement of small signals, industrial site signal isolation and long-distance transmission, etc.

The product includes power isolation, signal isolation, linearization, A/D conversion, and RS-485 serial communication. Each serial port can connect up to 256 ISO 4021 series modules, using ASCII code communication protocol or MODBUS RTU communication protocol for communication. Its instruction set is compatible with ADAM modules, and the baud rate can be set by code. It can be hung on the same RS-485 bus as control modules from other manufacturers, making it easy for computer programming.

AD/DA Analog Signal Data CollectorThe product is an intelligent monitoring and control system based on a microcontroller. All user set calibration values, addresses, baud rates, data formats, checksum statuses, and other configuration information are stored in non-volatile memory EEPROM.
The ISO 4021 series products are designed and manufactured according to industrial standards, with isolation between signal inputs/outputs. They can withstand an isolation voltage of 3000VDC, have strong anti-interference ability, and high reliability. The working temperature range is -45 ℃ to+85 ℃.

1. Communicationagreement
Communication interface: 1 standard RS-485 communication interface and 1 standard RS-232 communication interface.
Communication protocol: Supports two protocols, ASCII character protocol and MODBUS RTU communication protocol. The communication protocol can be programmed to enable network communication with various brands of PLCs, RTUs, or computer monitoring systems.
Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit.
Communication address: (00H-FFH) and baud rate (300, 600, 1200, 2400, 4800, 9600, 19200, 38400bps) can be set; The communication network can reach a long distance of 1200 meters and is connected through twisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication response time less than 100mS

2. Anti interference
Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectively suppress various surge pulses, protect the module, and the internal digital filter can also effectively suppress power frequency interference from the power grid.
