Mettler Toledo IND110 Membrane Keyboard Keypad Repair

Electrically, the IND110 Keypad Membrane Signal Converter provides an accurate and economical way to convert an analog strain gauge load cell(s) signal to a standard analog process signal. It does this by conditioning the analog input, converting it to a digital signal, normalizing and filtering it and then converting it back to an analog 4/20 mA signal. It would then be typically sent to a remote analog input such as a PLC.
In addition to the 4/20 mA output signal, two discrete setpoint outputs are provided for high and low-level signaling.
Mechanically, the IND110 Operator Panel Keyboard is self-contained in a plastic housing for installation onto a 35 mm DIN rail or optionally installed in either a stainless steel IP66 enclosure or a cast aluminum explosion-proof enclosure when environmental protection is required.
