The prognosis for autoimmune skin disease depends on your dog's specific diagnosis and the severity of symptoms. This is a potentially life-threatening condition... In general, this is a potentially life-threatening condition requiring extensive diagnostic tests and treatments.
As an example, take the case of a highly inductive load and an angle Î¸ = 60Â°. The triac is turned on atpoint A (60Â°). It will conduct during an angle Î± greater than 180Â°, in the neighborhood of 250Â°. It is blocked at point B:(290Â°).
Triac outputs can and do fail; despite the protection provided by on-board fusing. The only way to get near-100% protection for the PLC is to turn it (the PLC) OFF! Even that is not 100% protection. The cost of a small control relay is far cheaper than the cost of a module or CPU !!!
