HIMA F3236 module in the transportation industry

Make sure that the polarity of the external power supply is correct. If incorrect polarity and shorted load occur at the same time, the output element will be damaged and smoking or scattering chips may occur. Never connect to these modules a connector wired for F3XD32 or F3XD64. Otherwise, the protector function would not work and the internal elements may be damaged.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.” *4: For information on the module’s behavior during a CPU failure, see subsection A4.3.3, “Indicating Problem Severity and Status of Output Module.” *5: When F3SP22, F3SP28, F3SP38, F3SP53, F3SP58, F3SP59, F3SP66, F3SP67, F3SP71 or F3SP76 module is used, this setting can be specified in 16-point units. *6: 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

Operation of the protection circuitry

- If short-circuit occurs, the ON voltage increases and the short-circuit current is limited within the range 1-3 A. - Once the short-circuit condition disappears, output behavior is restored to normal. - If the short-circuit condition continues, the temperature of the output element increases due to the short-circuit current. If the temperature reaches approx. 160°C, the overheat protector will be activated and will shut down the output. - If the temperature drops by approx. 10°C after the overheat protector had been activated, the output is restored. - The overheat protector is not activated as long as there is no short-circuit condition and the module is operated normally within its specifications. - 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. - Both the short-circuit protector and overheat protector are designed to protect the output elements of the module against short-term short-circuit conditions. Never leave the module in prolonged short-circuit condition. Otherwise, the module enclosure may deteriorate or the PCB may be discolored.

ROM Packs 

ROM packs can be installed in sequence CPU modules and BASIC CPU modules and used to store programs or data. You can write to a ROM pack from the programming tool. At CPU startup, programs and data are read from the ROM pack into the memory for execution. Data written to a ROM pack includes program control information, programs, configuration data, various control tables, preset value tables for timers and counters, and comment management data. When used with sequence CPU modules, a ROM pack can store 1024 words of data. When used with sequence CPU modules F3SP22/28/38/53/58/59, a ROM pack can store circuit comments, subcomments and tag name definition (includes I/O comments.) You may not use ROM packs with F3SP66/67/71/76 sequence CPU modules (with network functions). You can use SD memory cards instead.
