TransducerModel LCA-9PC -Load Cell Amplifier Signal Conditioner with Db9 Connectors

SHARE

The LCA-9PC Module provides low-cost, dedicated signal conditioning for a single bridge type load cell or torque sensor. Model LCA-9PC comes with DB9 male and female connectors, which require soldering to user-furnished mating female or male wire connectors. On- board jumper selections include sensitivities from 0.5 mV/Vto 10 mV/V, bandwidths from 100 Hz to 30 kHz, and amplified outputs of 0 to ±5V, 0 to ±10V, 0-16 mA, 0-20 mA or 4-20 mA. Zero and span adjustments are via precision 25-turn low-tempco metal film potentiometers. The units can be operated next to the sensor with 4-wire hookup or at distances up to 1 km (3300 feet) with 6-wire hookup. An onboard 87.325 kQ resistor allows easy shunt calibration at the push of a button. Provision is also made for a user-furnished calibration resistor.
