LCM Launches New Trip Amplifier
LCM Systems, a U.K.’s designer, manufacturer and supplier of load cells and instrumentation announced the launch of the LCTA series of Load Cell Trip/Relay Amplifiers developed to provide dual volt free relay outputs from a load cell signal.
Aimed primarily at OEMs, this latest product provides an amplifier for applications such as hoist overload protection, crane safe lifting control and personnel lifting platform protection. The new amplifier module has the ability to power a single load cell or load pin or up to four 350 load cells connected in parallel. The volt-free relay outputs have a trip switching current of 10A at 230vac and can be adjusted independently by simply using a reference voltage to determine the adjustment value. For design engineers who wish to connect the LCTA to a remote display, there is also a 0-5v analogue output. Designers at LCM Systems have also included a shunt facility for calibration.
The LCTA can be supplied in a number of mounting options including an IP66 sealed plastic or metal case or ready for DIN rail mounting and has field screw terminal connections. Also, although the standard product requires a 12/24vdc power supply, there is the option with the DIN-mounted version to power from a 48vac supply.
