1. Application and Construction
The unit is used to increase the drive capability of existing encoder signals and to distribute the
signals to several channels. At the same time it provides potential separation between source
and target lines as well as level conversion.
In general, an incremental encoder output is limited to drive currents of 20 mA only on it's
impulse lines. The GV150 amplifiers increase the Fan-Out to 6 channels, each loadable with 20
respectively. 30 mA per line. The units can be used for encoder pulse transmission and for data
transmission applications as well.
As a standard, GV150 and GV151 provide TTL (RS422) inputs (A, /A, B, /B, Z, /Z)
With Option HTLIN1, the input is set to HTL level (12...30V), and only the signals A, B and Z
necessary (no inverted signals).
With option HTLIN2, the input is also set to HTL level ( 12...30V ), but all signals must be
applied (A, /A, B, /B, Z, /Z).
Each of the 6 output channels generates the signals (A, /A, B, /B, Z, /Z) .
GV150 provides always TTL/ RS422 standard and
GV151 has individually programmable output levels TTL or HTL

2. Connections, Switch Settings
a. The unit is supplied by a power connector on the front side.
The power supply range is 18 - 30 VDC.
b. For operation without potential separation, positions 3 and 4 of the internal DIL switch
S1 can be set to "ON". This will connect the input GND to the output GND and to the
Minus potential of the power supply
c. Pin 4 of the input connector provides an auxiliary voltage output, when the DIL-switch
positions 1 and 2 are set to "ON".
When DIL-switch positions 1 and 2 are set to "ON", never any external voltage
must be applied to pin 4!
The aux. output voltage is 5,5V/ 300mA with TTL inputs and 24V/ 300mA with options HTLIN1
and HTLIN2.

(GV151)
With GV151, you can select the desired output level (TTL/HTL) by setting the associated
position of the DIL switch to „ON“ (with the other position OFF).
Setting both TTL and HTL to ON at a time would result in HTL output.
For safety reasons, the default factory setting is always TTL like shown above.
