ISO 4011 Function Description
ISO 4011 is single-channel isolated signal-conditioning modules. Accepts outputs from Thermocouple, millivolt, volt and current signals.
Anaolg Input Module:
24-bit accuracy,have been calibrated all signal input before ex-factor.Also,Users can programme himself when modules working.Thermocouple input break line testing,linearity compensation and cold port temperature compensation.
Communication software:
Communication Interface: Module has one standard RS-485 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, no parity. (N, 8, 1)
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 70mS.
(2-wire) Alarm signaling output:
When choose products with alarm function,output two channels switching alarm signal,they are used to high&low control and alarm.
Anti-jamming:
Set checksum according to need.Its inside contains MOMENTARY bate diode.
