The LAC 74.1 is a universal analog amplifier for static/quasi-static DMS applications. It features adjustment of zero point, gain, and signal filter via DIP switches. Additionally, zero point and gain can be finely adjusted via potentiometers. It provides a short-circuit-proof analog output that can be operated as either a voltage output of 0-10V or a current output of 0/4-20mA. A safety circuit with logic output (OC) signals errors such as short circuits in the signal/supply/sense lines to the load cell, signal output outside the defined output range, and power supply voltage issues. LED indicators display measurement signal status and error status for quick functional checks.
The Flintec LAC 74.1 is a universal amplifier intended for static or quasi-static load cell (DMS) applications. It features adjustable zero point, gain, and signal filtering via DIP switches, with additional fine adjustment capabilities using potentiometers. The device provides a short-circuit-proof analog output that can be configured as either a voltage output (0-10V) or a current output (4-20 mA). This manual is written in German.
