Function of ISOAD A08:
ISOAD A08 is a 8 channel signal isolation acquisition module which is used for measuring
4-20mA/0-20mA current signal.
2.1 analog signal input
The acquisition precision of the product is up to the 24 bits. There are 8 channels for 4-20mA signal
input. Every channel has been isolated and all the signals of Sunyuan products have been calibrated
before delivery. Users could also program and calibrate the signals according to their needs by themselves
easily.
2.2 Communication protocol
Communication interface: 1 Road Standard RS-485 communication interface, or one road standard
RS-232 communication interface, which could be selected when ordering.
Communication Protocol: support standard Modbus RTU protocol and characters protocol. The
communication protocol could be used by programming. Network communication is achieved between it
and a variety of brands of PLC, RTU or computer monitoring system.
Data format: 10 bits. 1 start bit, 8 data bits, 1 stop bit.
Address: module address (0x00 ~ 0xFF) and baud rate (300 bps, 600 bps, 1200 bps, 2400 bps, 4800 bps,
9600 bps, 19200 bps, 38400bps) can be set; the communication networks, connected by twisted-pair
shielded cable, could reach up to 1200 meters. Communication interface is of high anti-jamming design,
± 15KV ESD protection, and the communication response time is less than 100mS.
2.3 Anti-interference
The checksum could be set customized. Inside the module there is transient suppression diodes
which can inhibit a variety of surge pulse and protect module and internal digital filter from grid
frequency interference.
