Mettler Toledo WM0800 IND110 A100 Keypad Switch Repair

Electrically, the WM0800 IND110 A100 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 WM0800 IND110 A100 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.
