Internal circuit
*1: The input current direction (source or sink) of the dry contact input can be selected by the
internal jumper plug. (Factory setting = current source) Refer to section 3.1.
3 side: current flows from input terminal to (
-
) terminal (current source)
1 side: current flows from (+) terminal to input terminal (current sink)
*2: The jumper plug of the DC power supply type must be set to 1 side.
*3: The input ON/OFF delay time of the DC input type can be changed by user. The setting range is
0 to 15 ms. (Default value = 10 ms) Refer to section 8.2.
*4: The input ON/OFF delay time of the AC input can be extended by user. The extension setting
range is 0 to 15 ms. (Default value = 10 ms) Resulting the default delay times are 35 ms (ON
delay) and 40 ms (OFF delay). Refer to section 8.2.
