Greeting Experts,
Can Programmable High-Side Driver IC Chips be used for I/O (signals leaving the fire enclosure) and qualify as a Limited-Energy Circuit? We are looking at using a High-Side Driver chip that is capable of outputting 11 amps at 24 volts. We are programming it to 2.8 amps (3.4 amp max). Can we use this for an I/O signal? The 61010-1 standard in section 9.3 for Limited-Energy Circuit calls out three methods: inherently limited circuit, over current protection device, and Regulating Network (see text below). Does a programmable High-Side Driver chip qualify as a "regulating network". Thanks to all, The Other Brian IEC/EN 61010-1 Ed2 9.3 Limited-energy circuit A limited-energy circuit is a circuit that meets all the following criteria. 3) a regulating network limits the maximum available current so that it cannot exceed the relevant value of table 13 in NORMAL CONDITION or as a result of one fault in the regulating network; _________________________ LECO Corporation Notice: This communication may contain confidential information intended for the named recipient(s) only.
