1. A relay terminal block for relaying a plurality of input signals input from an external measurement apparatus and outputting the plurality of input signals to an external terminal for monitoring or measurement, the relay terminal block comprising:
a relay module; and
a select signal generation device for periodically generating a select signal, wherein the relay module comprises:
a plurality of input signal transmission wires and one output signal transmission wire;
a first connector;
a second connector;
a third connector;
a controller;
a plurality of select signal transmission wires for transmitting the select signal; and
a plurality of terminals to which the select signal transmission wires are connected, wherein
the relay module periodically and sequentially selects one input signal specified by the select signal input via the plurality of terminals, from among the plurality of input signals, and outputs the selected input signal via any of the plurality of terminals and the output signal transmission wire, and wherein
the controller enables signals input via the first connector, the second connector and the input signal transmission wires to be serially output via the third connector when recognizing that the relay module is a master, and enables signals input via the input signal transmission wires to be serially output via the first connector or the second connector when recognizing that the relay module is a slave.
