Signal amplifier AI-2

programmableDC

Small signal amplifier that enables 2 programmable alarms to the values desired in each case. Each alarm level has an output for a voltage-free contact normally open (when unit is powered ) that withstands maximum 250V and 5A. It admits input signals from 5 mV to 2,500 mV. It has a power supply for Wheatstone bridge applicable to load cells and sensors. The amplified value can be viewed with a voltmeter, e.g., an ONIX V-12. In general, all applications requiring small DC signal surveillance with two levels of alarms through voltage-free contacts. Load and moment limiters for cranes, overhead cranes, elevators, platforms... The signals can come from load cells or pins. Alarm 1 can be used as early warning and Alarm 2 as an overload alarm.
