Intelligent Industrial Instrument(CNAOB)
The key features include:
21 signals including signals of thermocouple, resistance thermometer detector (RTD), direct voltage, direct current, resistance can be input freely, and the measuring range as well as the display resolution can be freely configured.
Modular output structure with control output options, including relay contact switch, solid-state relay driving voltage, non-contacting thyristor switch, single-phase thyristor zero-crossing or phase-shifting trigger signal, three-phase thyristor zero-crossing or phase-shifting trigger signal and direct current. Any of the outputs can be set freely as on-off control or PID control with configurable direct/reverse action modes.
Two ways of programmable alarm outputs are provided with a number of alarm modes including higher limit, lower limit, higher and lower limits, double higher limits and double lower limits, as well as alarm pattern options between absolute value type and deviation type. The alarm feature can also be temporarily disabled when applying the power.
A common programmable DC output module that can be freely switched among 0-10mA, 0-20mA and 4-20mA, either being used as control output or transmitting output.
Providing feeding outputs including DC 24V, 12V, 10V and 5V for external transmitter or other circuits
Employing RS485 serial communication and supporting standard MODBUS_RTU communication protocols for easy combination with third-party background monitoring software to build a total distributed control system
Function menu with all-character interface, detailed menu parameter description, human-oriented operation guide for quick start, in addition to simple and practical self-tuning capability of PID parameter will help you configure the instrument with easy.
Comprehensive self-detection and protect—the built-in software dog and dongle, together with monitoring module of the system ensure the system security by monitoring and controlling of program running out of track, EEPROM error, A/D error, cold junction compensation error, out-of-range, and output module status. In case of error, it provides automatic repair or prompt message and closes the output.
