ABSTRACT:
An input/output module for a programmable controller is provided. The input/output module has a digital input channel, and in order to prevent power losses previously incurred internally within the module, an electrical source is provided internally within the module for evaluating the status of a sensor connected to the digital input channel. The module receives no electrical energy via the digital input channel but outputs it. A reduction is thus achieved in the power loss incurred internally within the module. A method for operating an input/output module for a programmable controller is also provided.
