SenTec ST80 Column Display Controller can measure, display, alarm control, transmit output, data acquisition and communication of industrial process parameters such as temperature, pressure, liquid level, flow, weight and other industrial process parameters with the help of various sensors and transmitters. The measured value and set value can be displayed by analog bar and digital screen, and the display content can be switched freely.
Display Controller features
- All purpose signal input, optional by users. (thermocouple, thermistor, voltage, current, linear resistor, frequency)
- The measured value and set value can be displayed by analog bar and digital screen, and the display content can be freely switched.
- The measured value and the set value can be added or subtracted.
- Selection of 8 alarm control modes.
- The square root and small signal can be removed.
- The switch power supply type instrument can have 5 switching value outputs, one is the disconnection alarm of input part, and the other four are position control.
- The alarm relay can select the output state in case of breaking resistance, couple breaking and wire breaking faults.
- It can be used as counter and reversible counter instrument. Power on again after power failure to restore the count value before power failure, and clear the count value
- Preset number, upper and lower limit alarm and transmission output for count value.
- The associated alarm control mode can be realized.
- External power supply of 24 V, 30 Ma, 50 Ma or 100 Ma (can be used as two-wire transmitter power supply).
- The measurement value or internal given value transmission output: 0 ~ 10mA, 4 ~ 20mA, 0 ~ 5V, 1 ~ 5V, 0 ~ 10V.
- It can provide RS 485 asynchronous serial communication mode with multi host, single host and no host mode. Communication data verification is in accordance with the American data communication standard of c r C-16, with high reliability cycle and bar code verification.
