10.9 WIRING DISCRETE DIGITAL OUTPUTS
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 PN 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 PN 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 configuration 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
The above diagrams are applicable to systems implementing a solid-state load or relay connected to
an S200 PN output. Load LED and resistor or relay coil (reverse diode) can be in ether leg of the
power circuit.
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.
