*1: If an inductive load, such as a relay, is to be connected, a surge protector is also required on the load side. Connect
a surge protector or a diode across the load nearby so that the module output terminal voltage will not exceed the
specified operating load voltage range. For details, see Subsection A3.6.5, “Connecting Output Devices.”
*2: The contact operation of the output block of the circuit and the LED display operate independently and thus may be
inconsistent in the event of an error.
*3: For information on the module’s behavior during a CPU failure, see subsection A4.3.3, “Indicating Problem Severity
and Status of Output Module.”
*4: When F3SP22, F3SP28, F3SP38, F3SP53, F3SP58, F3SP59, F3SP66, F3SP67, F3SP71 or F3SP76 module is
used, this setting can be specified in 16-point units.
CAUTION
Ensure that the polarity of the external power supply is correct. Otherwise, a short-circuit
condition may damage an output element and cause smoldering and scattering of chips.
Beware that wrongly connecting a connector wired for F3XD32 or F3XD64 to the
module may disable the protectors and damage internal elements.
Note
Operation of the protection circuitry:
- If short-circuit occurs, the ON voltage increases and the short-circuit current is
limited within the range 1-3A.
- If the short-circuit condition is removed, normal operation resumes.
- If the short-circuit condition persists, the short-circuit current may cause the
temperature of the output element to reach approx. 160°C, triggering the overheat
protector to shut down the output.
- If the temperature of the overheated output element then drops by about 10°C,
normal operation resumes.
- The overheat protector will not be triggered if the module is operated normally within
its specifications with no short-circuit condition.
- Both the short-circuit protector and overheat protector are designed to control
outputs individually. Under some short-circuit conditions, however, the overheat
protector may shut down not only its associated output but also other outputs.
- Short-circuit and overheat protectors are designed to protect the output element
against short-term short-circuit. Never leave the module in prolonged short-circuit
condition. Otherwise, the module enclosure may deteriorate or the PCB may be
discolored.
