Page 207: Load Short-Circuit Protection
7 Digital Output Units 7-4-3 Load Short-circuit Protection Purpose This function is used to protect the output circuits of the Digital Output Units when an external connec- tion load short-circuit occurs. Details on the Function As shown in the figure below, normally when the output bit (OUT) turns ON, the transistor turns ON and then output current (Iout) will flow.
Page 208 7 Digital Output Units Restrictions on Use The load short-circuit protection function only protects internal circuits for a short period. As shown in the figure above, the load short-circuit protection of this NX Unit is automatically released when the Tj equals to Tr. Therefore, unless the cause of short-circuit is removed, ON/OFF operations are repeated in the out- put.
Page 209: Push-Pull Output
7 Digital Output Units Push-pull Output The Digital Output Units with the ON/OFF response time of 1 μs or less use a push-pull output to increase the speed of the output ON/OFF response. For this type of the Output Units, use the single load power supply for the I/O power and connected external devices.
Page 210: Precautions When Using The Relay Output Units
7 Digital Output Units Precautions when Using the Relay Output Units This section describes precautions when using the Relay Output Units. Relay Service Life The service life of Relay Output Units depends on the type of load, contact current and ambient tem- perature.
Page 211 7 Digital Output Units Inductive Load The life of the Relay varies with the load inductance. If any inductive load is used, we recommend that you use a contact protection circuit. Contact Protec- tion Circuit on page 7-21). Be sure to connect a contact protection circuit in parallel with every DC inductive load that is connected to the Contact Output Unit because the usage of a contact protection circuit has a significant effect on the service life of the contact.
