ISO 4021Series A-D Converter Function Description:
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 (300600120024004800960019200
38400BPS), Max. Communication distance: 1200m, connect by both twists shiled cable. ± 15KV ESDprotection, communication response time is less than 100mS.
Anti jamming:
Set checksum according to need. Its inside contains MOMENTARY bate diode, can
Restrain surge impulse, protect modules.
