Operation Manual

8085.5010

Level Converter, Potential Separator and Direction

Signal Decoder for Incremental Encoder Signals

 Signal inputs A, B, Z and /A, /B, /Z, adjustable to either RS422

format or TTL level or HTL (10-30V) level

 Signal outputs A, B, Z and /A, /B, /Z, likewise adjustable to either

RS422 format or TTL level or HTL (10-30V) level

 Potential separation between input and output

 Conversion of a A/B quadrature direction signal to a static direction

output and vice-versa

 Encoder connection alternatively via SUB-D-connectors or parallel

screw terminal strips

1.3. Installation The device is only allowed to be installed and operated within the permissible temperature range. Please ensure an adequate ventilation and avoid all direct contact between the device and hot or aggressive gases and liquids. Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it must be ensured that no danger can arise by touching the disconnected voltagesources.

2. Introduction This universal level converter, on the input side, can accept single channel and quadrature encoder signals with either RS422 format or TTL level or HTL (10-30V) level. Where the signal provides direction information, the direction may be defined by either an A/B-90° phase displacement, or by a static direction signal.

4. Switch settings The front DIL switches require a few settings depending on the signal levels and the mode of indicating the direction on inputs and outputs 4.1. Input characteristics You can set the desired input characteristics by switch DIL2, positions 6, 7 and 8 0=OFF 1=ON 8 7 DIL2 6 1 (Z) 1 (B) 1 (A) 0 (Z) 0 (B) 0 (A) 5 4 3 2 1 Single-ended input: Only signals A, B and Z are connected, the inverted inputs /A, /B, /Z remain unconnected.

4.3. Definition of the direction of rotation The unit is designed to evaluate quadrature direction information (A/B, 2x90°) and static direction information as well. Furthermore it can convert the direction information from one format to the respective other format. Positions 3, 4 and 5 of switch DIL2 provide individual selection for input and output.
