Auto Reset Operation
IMPORTANT | The 1746-OB6EI and 1746-OB16E modules perform auto-reset under overload conditions. When an output channel overload occurs, that channel will limit current within milliseconds after its thermal cut-out temperature has been reached. While in current limit, the output channel can cool below the thermal cut-out temperature allowing the module to auto-reset and resume control of the output channel as directed by the processor until the thermal cut-out temperature is again reached. Removing power from an overloaded output channel would also allow the output channel to cool below the thermal cut-out temperature, allowing auto-reset to occur when power is restored. The output channel would operate as directed by the processor until the thermal cut-out temperature is again reached. To avoid auto-reset of an output channel under overload conditions, an external
mechanical fuse can be used to open the circuit when overloaded. | ![]() |
