S200 Position Node Installation Guide
For systems desiring to use input voltages exceeding the 5V rating for DINP5 and DINP10 an external current
limiting resistor must be used. The resistor should be in series with the input line. The following table indicates the
recommended resistor values.

The S200 Position Node has 3 outputs: Fault, /Run, and one user-configurable. These outputs can handle no
more that 50mA current and no higher than 30Vdc circuit design. Each output is ‘uncommitted’. That term simply
means that both pins of each output are user-wired, not tied to a common rail. The purpose for this is to allow
greater flexibility in the end application. The outputs are solid-state transistors and are polarity sensitive: Proper
polarity must be observed. All three outputs are electrically identical.
Fault Output: The fault output is a dedicated normally closed output for user use. This means that the output is in
the on state when no fault is present. If a fault is detected the S200 Position Node will turn this output off. This
method is considered fail-safe in that many failure modes of this circuit will cause the host to detect a fault.
Run Output: The Run output is a dedicated normally closed output for user use. This means that the output is in
the on state when the S200 POSITION NODE is ready to run. Internally, the Run output is conceptually
equivalent to the Power Stage Enable line. If the power stage is enabled the output will be on. If the user disables
the drive, ether by hardware or software disable, or if the drive detects a fault and shuts down the power stage
then the output will open. This logic is typical of systems requiring holding brakes.
User Configurable Output: The S200 Position Node User’s Guide has information regarding the function of this
output.
Typical wiring configurations of any of these outputs are either direct logic connection back to a host controller or
to a relay. The following diagrams show typical wiring configurations.
Wiring Discrete Output to LED or Opto Isolator
WARNING
Connection of any inductive load, such as a relay coil, must use
diode suppression across the coil to prevent excessive voltage
kick-back at turn off.
Outputs are not overload protected. Do not exceed maximum
rated current.
