ISOAD Function Description
ISODA signal isolated D/A converter module,can output one channel voltage/current signals,
or 2-channel common ground and isolation current/voltage signals.
1. Analog signal output
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 RS-485 interface or 2 standard RS-232 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.
Set checksum according to need. Its inside contains MOMENTARY bate diode,can
Restrain surge impulse,protect modules.
