ULTRASONIC LEVEL TRANSMITTER WITH MODBUS(RS485) COMMUNICATION

MODEL NO. MS0410

It has following features:

• Analogue output 4-20mA
• Digital output for relay operation (On/OFF)
• Rs485 standard Modbus Communication.
• Auxiliary Power supply 24vDC 600mA

Introduction:

This is microprocessor based Ultrasonic level transmitter. It has Multifunction Instruments It is capable of monitoring Virtually Any Short or Medium Range of Non-Contact Ultrasonic Level Measurements of Liquids, Solids or Slurries. In this Instrument User can take measurements of Roller Lift of mills, water level and select the range in the range parameter and set action in Action parameter. It has One Analog Output 4-20mA (Isolated) and two digital control output (we can also define these two digital control output as relay1and Relay2).

Modbus communication protocol:

1. Baud Rate: 9600 B/S
2. Data Bits :8
3. Party: None
4. Stop Bit: One
5. Communication Mode: RTU 8 Bit

The instrument has standard Modbus communication via RS-485 The user can read parameter value and display levels value etc.

Note:  Modbus data 35000 received when over range message is received on the display

Note: User can change Modbus Id (0-255) in Modbus id parameter as per requirement.
