Description

Display module for pressure transmitters
The display module LCD-SHD-Modbus has been specially designed for the pressure transmitter PREMASGARD® SHD / SHD-SD / SHD 692 and DIN EN 175301-803-A connector. The display can be mechanically rotated and tilted, and the display content can be rotated in increments of 90° to achieve the ideal reading position. In addition to the actual pressure, it can display the min/max measured values or alternatively the output signal of the sensor.
The configured display unit converts the standard signal (0-10V) of the pressure measuring transducer into a Modbus signal (RTU) and calculates the pressure in the selected unit for the display indicator. The following parameters can be set: Measuring range of the sensor, physical unit (bar / kPa / psi / inWC / mWC / atm), interval of the min/max values (1h / 6h / 12h / 24h / ....), number of values for averaging, display mode, direction of the display content, contrast and backlight. The unit is configured using micro button switches on the circuit board inside the housing.
