In line with the encoder cable
The EC-LV is an in-line encoder signal conditioner, a frequency to voltage converter for the digital pulses of a Wheel Pulse Transducer or of slip rings with a built-in encoder. Besides the standard encoder outputs A, B, I and A⊕B, it delivers a ± 10 V DC voltage proportional to angular velocity, a 0 to 10 V DC voltage proportional to angular position from 0 to 360°, and a 10 V peak-to-peak sine-cosine output. It runs on 5 to 20 V DC, draws 270 mA at most, measures 142 × 94 × 56 mm, weighs 351 g, is rated IP40 and works from −40 to 100 °C.
The EC-LV is added in line with the encoder cable, so the voltages need no post-processing and no additional power supply. It has two connectors, marked ENCODER and POWER+SIGNAL, and the standard encoder signals remain available alongside the two voltages. Rotation direction and speed range are set with toggle switches on the unit; it comes with two preset speed ranges, which can be changed on special request. Its input is protected against reverse voltage up to 20 V DC.
It is used with Wheel Pulse Transducers to record wheel speed and distance, down to near-zero speed, and to feed recorders that cannot read encoder pulses.
