for Incremental Encoder Signals
Universal encoder interface, applicable as level converter, encoder splitter and
encoder cross switch
Two encoder inputs A, B, Z and /A, /B, /Z, adjustable to either TTL/RS422 level
or to HTL (10-30 volts) level
Two signal outputs A, B, Z and /A, /B, /Z, likewise adjustable to either TTL/RS422
or HTL (10-30 volts) level
High frequency range ( 1 MHz )
Contactless and bounce-free switch-over between the encoder channels, by remote
control signals
Power supply 12-30 volts DC, auxiliary output 5 volts for encoder supply

Page 7: Asymmetric Ttl Inputs
A, B and Z may at any time also be independent single signals, e.g. from proximities, photocells etc. Since the level of every channel is selected individually (see DIL-switch), it is possible to use different levels on the inputs. Consequently it is e.g. possible to take the position information from the A, /A, B and /B channels of a RS422 encoder, but to add the corresponding Z index pulse as a HTL signal from a remote photocell With HTL signals, the switching threshold lies between 6.5 and 8 volts. -
Page 8: The Front Leds
3. The Front LEDs The green LED is lit as soon as a power supply voltage is applied to the unit. The yellow LED indicates the state of the Control inputs and the basic function of the unit: Yellow LED off: Control1 and Control2 are either both LOW or both HIGH at the same time. In this case the unit operates as a splitter (both outputs are connected to the same input) Yellow LED on: Control1 and Control2 have different states. -
