The Aptifirst LCA20 process monitor/controller for weighing and similar operations produces 4 to 20mA and 0 to 10V analog outputs from any standard strain gauge input. Auto tare and peak hold on the analog output are operated via voltage-free contact closures. The RS232/RS485 communication module supports MODBUS RTU, ASCII, MANTRABUS1 and MANTRABUS2 protocols. The unit is equipped for 6-wire strain gauge input and has a 5V bridge excitation power supply sufficient to power up to 10 350Ω load cells. An on-board display is visible through an optional transparent case lid.
