Product and Applications Description
The push button interfaces UP 220/21 and UP 220/31
are binary input and output devices for installation in in-
wall boxes (∅ 60 mm, depth: 40 mm).
Each of the two (UP 220/21) respectively four
(UP 220/31) channels may be used either as an input
for potential-free switch / push button contacts or as an
output for control of a light emitting diode (LED). The
required scanning / control voltage is provided by the
push button interface (requires no additional power
supply).
For example, up to 2 switches/push buttons with one
potential-free contact each or one 2-fold push button
with two potential-free contacts may be connected to a
push button interface UP 220/21. Up to 4 switches/push
buttons with one potential-free contact each or up to
two 2-fold push buttons with two potential-free contacts
each may be connected to a push button interface UP
220/31.
The connection is carried out via a cable set which is
permanently connected to the push button interface.
The connecting cables between switches/push buttons
and the push button interface may be extended up to
10 m. It must be ensured that twisted cable pairs are
used.
Commands can be given to actuators via the connected
switches/push buttons, e.g. for defined switching on/off,
for dimming fluorescent lamps or for raising/lowering
venetian blinds and adjusting the louvres.
Each channel, which is configured as an output, can
drive an output current of up to 2mA for controlling a
light emitting diode (LED).
With the ETS the application program is selected, its
parameters and addresses are assigned appropriately,
and downloaded to the push button interface UP 220/21
or UP 220/31.

A single input (A, B, C, or D) can be configured for one
of these functions:
• Switching (on, off, toggle) on leading, trailing, or
leading and trailing edge
• Send value (8-bit value, 16-bit value, 16-bit floating
point) on leading, trailing, or leading and trailing edge
• Switching (on, off, toggle) after short / long push
button action
• Send value (8-bit value, 16-bit value, 16-bit floating
point) after short / long push button action
• adjustable period for long switch operation can be
selected
• cyclical sending possible
• single button dimming
• single button control of solar protection
• single button group control
• 1-bit scene control
• 8-bit scene / effect control
• impulse counting with / without limit value monitoring
• 8-bit
