(1) Connection Example and Specifications of EDM1 Output Signal
Connection example and specifications of EDM1 output signal are explained below.
For safety function signal connections, the input signal is the 0 V common and the output
signal is the source output. This is opposite to other signals described in this manual. To
avoid confusion, the ON and OFF status of signals for safety functions are defined as fol-
lows:
ON: The state in which the relay contacts are closed or the transistor is ON and current
OFF: The state in which the relay contacts are open or the transistor is OFF and no cur-
