Abstract
A DC circuit for a sensor or control device is disclosed which has a primary output, and a secondary output which, at the option of the user, is either the complement of the primary output or an unrelated output signal such as an alarm signal. The user selects the mode of operation of the secondary output terminal by selecting the polarity of a supply voltage applied to the control device at two input terminals.
