LCA-RTC Module - Load Cell Amplifier Signal Conditioner

The LCA-RTC Module offers a low-cost, dedicated signal conditioning for a single bridge type load cell or torque sensor. It comes with removable screw-clamp terminal connectors, which do not require soldering. Our LCA-9PC module offers DB9 male and female connectors, which require soldering to the 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 LCA-RTC (Load Cell Amplifier Signal Conditioner) 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 26V DC with load currents from 10 to 60 mA, the latter applying when the unit provides 10V DC excitation to a 350-ohm load cell and delivers a 20 mA analog output.

Features include:
Power Requirement 12 to 26V DC
Bridge Excitation 5 to 10V DC
Bridge Sensitivity 0.5 mV/V to 10 mV/V
Push Button Shunt Calibration Network
Two-Pole Low Pass Selectable Filter 100 HZ to 30 kHZ
Analog Outputs 0 to ±5V, 0 to ±10V, 0-16 mA, 0-20 mA or 4-20 mA
