Xinmin Electronics XM Series Intelligent Digital Display Control Instruments Controllers and Systems

XM series intelligent digital display control instrument

1. Product Overview

XM series intelligent digital display control instrument is used in conjunction with weighing,temperature,pressure,liquid level,flow and other sensors and transmitters to measure,display,control,alarm and transmit various physical parameters. It is a high-performance,multifunctional intelligent instrument.

2. Product features

1. The instrument is suitable for sensors or transmitters such as weighing,temperature,pressure,flow,liquid level,etc. It is suitable for standard voltage and current input signals,and the display range can reach -1999~9999 words.

2. It can store on-site data without losing information during power outage,and it has automatic digital temperature compensation and automatic zero stabilization system.

3. Adopt advanced fully automatic digital local adjustment system,no need for potentiometer adjustment.

4. The use of photoelectric isolation transmission output improves the anti-interference ability and user control system design flexibility.

5. The instrument is powered by a switching regulated power supply,which has great voltage adaptability and strong power supply anti-interference performance.

6. It has upper and lower limit control or alarm functions.

7. Use RS232 or 485 serial interface to communicate and network with the host computer.
