4-20mA Loop Powered 4 Digit LED Plug-On Display With Alarm Point
Plugs inline with a DIN 43650 connector, 4 to 20 mA powered pressure transducer to display the current pressure. 2 × Open drain output for alarms/set point indications.
The LED series is a universal 4 digit LED plug-on display for transmitters with 4-20 mA 2 wire output and fitted with DIN43650 connector.
The plug-on display simply fits between the transmitter plug and connecting cable socket and is powered from the 4-20 mA current loop signal of the transmitter. No additional power is required.
Display settings are stored in non-volatile EEPROM, and can be easily modified through the menu using two programming buttons. Calibration parameters (zero, span, decimal point position, filter, and set-point level) can all be reprogrammed and stored and retained when power is removed. The display assembly inside the enclosure can be rotated through 90º steps, which will suit any mounting angle and simply installation.
Typical applications for the plug-on display include use on pressure, temperature, level, RH, or flow transmitters for local readout, alarm activation or control.
