0-75mV|0-20mA to RS232|RS485 Modbus RTU Converter Introduction:
ISO4021 series realizes sensor to host signal acquisition for testing analog signal or remote applications. Software configurable for a wide variety of sensor types, including: Analog input, analog output, and digital I/O, ISO4021 series are widely used in RS232/485 automation control system, 4~20mA/0~5V signal testing, small signal testing, Monitoring &Control, remote data acquisition applications.
Including power supply isolation, signal isolation, linearization, A/d conversion and RS232C/RS485 serial communication. For up to 256 channels per serial port, ISO4021 Series modules, adopts ASCII format and MODBUS, its injunction fully encapsulated to ADAM modules, baud rate can be intercalated by code, can be used in the same RS485 lines with other manufacturers modules, convenient for computer programme.
ISO4021 series modules is SCM based intelligent monitoring and control system, with all calibration, High and Low alarm, address, input ranges, baud rate, data format and linearizing parameters stored in EEPROM non volatile memory.
ISO4021 series modules are designed as industrial standard, input signal/out signal isolation, 3000VDC isolated. Temperature range is minus 45 to + 85 centigrade


ISO 4021 Sereis A-D Converter Functions:
ISO 4021 isolated modules to test one channel voltage/current signals, or 2 channel common ground and isolation current/voltage signals.

Anaolg Input Module:
24 bit accuracy, have been calibrated all signal input before ex factor. Also, Users can programme himself, Two input types must be same when testing two signals.

Communication software:
Communication Interface: 1 standard RS485 interface or 2 standard RS232 interface
Communication agreement: Standard ASCII, MODBUS, can make network communicate

With PLC, RTU or watch software.
Data format: 10 bit, 1 start bit, 8 data bits, 1 stop bit.
Communication address (0~255) and baud rate (300\600\1200\2400\4800\9600\19200\
38400BPS), Max. Communication distance: 1200m, connect by both twists shiled cable. ± 15KV ESDprotection, communication response time is less than 100mS.
