Transducer Techniques, LLC Load Cell Amplifier Signal Conditioner with DB9 Connectors LCA-9PC

MODEL LCA-9PC 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/V to 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 kΩ resistor allows easy shunt calibration at the push of a button. Provision is also made for a user-furnished calibration resistor. Power requirements are 11.8 to 26 Vdc with load currents from 10 to 60 mA, the latter applying when the unit provides 10 Vdc excitation to a 350 ohm load cell and delivers a 20 mA analog output.
