1. Application
The SV 211 encoder splitter has been designed for clean and trouble-free distribution of the
output signals of sine-cosine type encoders to several target units.
On all sine output channels the same signal format is available as on the input site, including a
reference impulse (if available on the input site). All sine-cosine signals use the differential
1 Vpp format which is most common with industrial sine-cosine encoders.
Current signals according to the 11 µA standard are not supported by this unit.
The diagram below explains the sine signals.

2. Connection Diagram
For wiring of the sinusoidal signals the unit provides 5 Sub-D-9 connectors (X1, X2, X3, X4 and
X5). For all other connections 2 screw terminal strips are available (X6 and X7). All Sub-D 9
connector housings are connected with the GND potential.

2.1. Power and Encoder Supply (X6/X7)
The unit operates from a DC power from 17 to 30 volts which must be applied to the front
terminals X7/1 (+) and X7/2 (-). The +24V supply at the terminal X7(1,2) is a potential separated
input.
With unloaded state the current consumption is about 50 mA (encoder supply line and output
channels unconnected).
Terminals X6(1,2) selects the level of the auxiliary encoder supply output (24 V). More details
are explained under section 2.2 (Encoder connection).
The terminals X6 and X7 are encoded to avoid an inverted connection between both!

SV21101b_e.doc / Feb-13 Page 6 / 8
2.2. Connection of the Sine-Cosine Encoder (X5)
The encoder can be connected via the front Sub-D-9 connector marked X5 (male connector on
unit side, female connector on the encoder cable). Only encoders with differential sine-cosine
signals of 1 Vpp can be used (0.8 Vpp - 1.2 Vpp). At any time the signals sin+/sin- and cos+/cos-
must be available. Where an additional reference marker pulse is used, also the signals
ref+/ref- must be applied.
Pins 4 (+) and 5(-) of the Sub-D-connector provide an auxiliary power output for the encoder
supply. When terminals 1,2 of the front X6 connector is unconnected, the aux. output voltage is
automatically about 5.2 volts (max. 150 mA). Where the encoder requires another supply
voltage (e.g. 24 volts), an appropriate voltage can be applied remotely to terminal X6(1,2).
Please note that the metallic housing of the Sub-D input connector is internally connected to
the common GND potential of the unit.

2.3. The Sine-Cosine Outputs (X1, X2, X3 und X4)
All Sub-D-outputs provide an image of the sine-cosine input signals, however with a fixed
offset voltage of 2.5 volts with respect to GND. This allows a clean and trouble-free distribution
of the input signal to four target units.

It is mandatory to use cables with pairwise twisted wires for all sinusoidal signals
sin+/sin-, cos+/cos- and ref+/ref-.
For trouble-free signal transmission the target unit must provide terminating resistors
at the end of the signal line (in each case 120 ohms between signal+ and signal-)
Since on the inputs the unit already uses in-built termination resistors, no further
measures must be taken on the encoder side.

SV21101b_e.doc / Feb-13 Page 7 / 8
It is recommendable to connect the cable shield directly to the metal housing of the
associated counterpart connector. This ensures that the cable is connected with the GND
potential in any case via SV211.
3. The Front LEDs
The green LED is lit whenever the power supply of the unit is on.
The yellow LED indicates the availability of the encoder supply +5V. The yellow LED is lit
whenever the supply is available.
