The maximum voltage that can be applied to an input terminal is 24 volts DC.
Never apply AC voltage to an input terminal.
If the sensor output goes high at the limit,
choose the program option “closed.” If the
output is low at the limit, select “open.”
Wiring a Mechanical Limit Switch
If the sensor output goes low at the limit,
select the option “closed.” If the output is
open, or high voltage, choose “open.”
Limit Sensors
Some systems use active limit sensors that produce a voltage output rather than a switch or relay
closure. These devices must be wired differently than switches.

Wiring Inputs
The FSC-01 input circuits can be used with sourcing or
sinking signals, 5 to 24 volts. This allows connection to
TTL circuits, PLCs, relays, and mechanical switches.
Because the input circuits are isolated, they require a
source of power. If you are connecting to a TTL circuit
or to a PLC, you should be able to get power from the
PLC or TTL power supply. If you are using relays or
mechanical switches, you can use the FSC-01's built-in
24 volt power supply.
Note: If current is flowing into or out of an FSC-01
input, the logic state of that input is low. If no current is
flowing, or the input is not connected, the logic state is
high.
The diagrams on the following pages show how to
connect the FSC-01 inputs to various devices.

If your sensor has an open collector output or
a sinking output, wire it like this:
Other sensors have sourcing outputs. That
means that current can flow out of the sensor
output, but not into it. In that case, wire the
sensor this way:
You can use normally open or normally
closed limit switches. Either way, wire
them as shown here.
