PURPOSE:To increase the range of the use of an output insulating relay unit by attaching an operation indicating lamp for the digital output contact of a sequencer, etc., on the monitoring operation face of the relay unit and by providing each relay contact, used for an output signal to a load, with a three-notch switch. CONSTITUTION:To the contact between digital output contact DO1 and three- notch switch SW1, contact operation indicating lamp L1 is connected at its one terminal via a resistance, and its other terminal is connected to power source N1. When output insulating relays X1-Xn operate in response to contacts DO1-DOn, their contacts x1-xn are opened or closed to put loads MV1-MVn in operation. At this time, digital output contacts DO1-DOn operate to operate output insulating relays X1-Xn, and operation indicating lamps also turn on, thereby turning on operation lamps of relays X1-Xn. Further, signals of one contact each of relays X1- Xn are outputted as operating output signals to loads MV1-MVn, and the operating device of switches SW1-SWn controls the operating output signals to the loads. |
