The LS-C30 amplifies the output of bridge-type resistive sensors (pressure sensors, load cells) to ±10 Vdc. This allows low-level sensors to be used with the LS-C10, LS-C41 and C2 controllers. High performance by design: The LS-C30 is a dual channel small signal differential signal amplifier with 4 channels of optically isolated, switched outputs that function as trip level indications. The wide dynamic calibration range and low noise allow amplification of signals from very low-level sensors.
