WEIGHT ALARMING CONVERTER MODEL S1E

APPLICATIONS

The model S1E weight alarming converter è is an analog instrument specifically designed for overload control in industrial or residential electronic weighing, both for system using strain gage load cells or standard mA signals. Typical applications are: - Overload control for lifting machines - Level alarms and indication for silos, hoppers, ecc. - Alarms for any process variable using a standard mA signal - Process variable transmitter for PC/PLC input

MAIN FEATURES

- Multifunction input (mV, mA) - Suitable for max 4 strain-gage load cells - Load cell supply short circuit protection - Two optoisolated alarm outputs - Internal failure control circuit - 0-10 V c.c. analog output factory calibrated - DIN rail mounting construction
