TR-Electronic analog encoders with remote teach-in

TR-Electronic is offering analog encoders with a multifunctional analog interface. A 16-bit D/A converter processes the multiturn position signal and supplies an analog output signal proportional to the angle of rotation. The speed signal can also be used, with which a speed feedback can be implemented.

The position signal is scaled by setting the start and end point fitting to the mechanics — meaning the maximum bandwidth of the analog signal is always used for the desired mechanical movement range. Up to now, such a teach-in has taken place with a button on the device. Programming the encoder is achieved via a teach-in button on the encoder or remotely via two digital inputs on the M12 connecting cable.

The signal output is either a voltage or a forced current. The current interface with a minimum current of 4 mA (‘live zero’) is said to offer the highest reliability by compensating for voltage drop detecting interruptions in the line.

The analog interface with teach-in function is available in all mechanical versions of the company’s current generation of encoders: size 58 with solid shaft, blind and hollow shaft up to 15 mm, in size 80 with through hollow shaft up to 27 mm, and in size 110 with through hollow shaft up to 50 mm.
