GV155:All encoder inputs and outputs are designed for TTL level
(RS422 line driver signals).
GV156: Encoder inputs are available with TTL/RS422 format (standard) or with
HTL (15-30V) format against ordering information “Option HTLIN1”. Encoder
outputs are individually adjustable to either TTL/RS422 level or HTL (15-30V)
level by DIL switch setting.
*) Only with model GV155 but not with model GV156
The signal ways shown in the block diagram correspond to all control inputs in LOW or
unconnected state

2. Applications
Typical applications can be found in drive technology and general automation, where impulse
signals or analogue control lines have to be commutated between several peripheral sources
and target units.
A relays circuit basically could do the same, but can become costly and also unreliable in
operation, by contact overlapping, bouncing and general problems with switching of small scale
signals, micro currents and high frequencies. Often, there are also unacceptable screening and
wiring problems when using relays.
Use of GV155 or GV156 avoids any of these problems and allows proper and reliable switching
of digital and analogue signals. There are 14 control inputs C1…C14 that can operate from
mechanical switches or under PLC control.
Application Example:
Some times, in applications with electronic synchronizing of drives, there are two master drives
that need to be synchronized by turns with only one slave drive, depending on the actual
production. The subsequent schematic shows how to solve the analogue and digital signal
commutation required:
