Description

This very flexible digital load cell amplifier for weighing single or multiple load cell applications, offers an easy one-pass calibration and fast setup. It is also equipped with relays, data port and display.

The LCA20 load cell weight indicator offers options of local or remote LCD displays, isolated 4-20 mA 0-10 V analogue outputs, relay outputs for control or alarm functions, for example, in crane overhead alarms, and also for, in-flight compensation commonly used in silo bag filling applications. The RS232 or RS485 options provide for digital communications (including setup) and can support label or ticket printers.

Analogue and digital output, set point and display capabilities AC or DC powered, IP65 NEMA 4 protected.

The LCA20 (load cell amplifier) replaces the LCA15 and provides increased functionality, improved performance and takes advantage of new technology.

IP65 bulkhead mounting ABS case – also available as a DIN rail or PCB module – model LCB-20

For a PCB module version, see model LCB20 load cell amplifier and digitiser.

Can be used in conjunction with the LCI load cell failure alarm, which is designed to continuously monitor the condition of individual load cells and activate an alarm when faults in the system are detected, therefore providing increased safety and cost savings onsite for all weighing systems.
