The LCA20, a flexible digital signal conditioning amplifier for single or multiple load cell applications, has been launched by Mantracourt. The LCA20 load cell weight indicator offers options of 3 programmable digital inputs including Auto Tare, Peak Hold and Reset, whilst also providing two relay outputs for control or alarm functions. This is able to support up to ten 350Ω load cells. 

Additional features include a simplified digital set-up via PC, 10 point linearisation and the provision of measurement speeds of 10 or 80 samples per second. The LCA20 provides both RS232 and RS485 options for digital communications (including setup) and can support label or ticket printers. Furthermore, the LCA20 is enabled with an easy one-pass calibration and fast setup procedure.

The LCA20 supports Mantrabus 1 & 2, MANTRA ASCII 2 and MODBUS RTU protocols. It is housed in a ROHS compliant enclosure and is environmentally sealed to IP65 / NEMA 4  (dimensions 200 x 120 x 75 mm). DIN rail or PCB module versions are also available. The LCA20 also caters to existing LCA15 users in that it features a full LCA15 emulation mode.

“The LCA20 takes advantage of new technology, it replaces and builds on our previous LCA15 load cell amplifier, providing increased functionality and improved performance,” said Dave Porter, Technical Sales at Mantracourt. “The core design is based on existing, proven technology but it has now been updated to ensure that we continue to meet the needs of end-users in the field.”
