nnnn

LED-W11X is a digital indicator for installation directly in a 4-20 mA loop

nnnn

without need for external power.

nnnn

The indicator is equipped with bright, easy-to-read LED digits.

nnnn

LED-W11X is designed for field mounting on a wall or, by means of mounting

nnnn

kit, on a pipe or a DIN-rail. It has a rugged and splash proof housing with

nnnn

protection IP65/NEMA4X.

nnnn

The scale is easily programmable, without reference signal, by two internal

nnnn

pushbuttons for any values between -1999 and 9999.

nnnn

A temperature transmitter can be integrated for direct sensor input.

nnnn
