An input-output unit for serial-parallel conversion has a simple structure and is capable of controlling various devices to be drive-controlled by a serial signal together or transmitting output signals from various sensors to a control system together by converting them into serial signals. For this purpose, the input-output unit has plural input-output blocks in series for inputting control signals into the various devices for transmitting output signals from the various devices, via an input-output connector, and a relay block having a serial terminal to be connected to the control system and a signal converter for converting between serial signals transmitted to and from the control system and parallel signals transmitted to and from the input-output blocks via a multipolar joint connector to be connected to each input-output block.
