11.3 Electrical specification
Descriptions and specifications of the terminals are listed
in the table below.
Note: Corresponding to “Digital input type 1” defined in
IEC61131-2
Length of cabling connected to the above terminals other
than ST1, ST2, and STC must be twenty (20) meters or
shorter. Length of cabling connected to ST1, ST2, and STC
must be one (1) meters or shorter.
*1) These are the terminal symbols on the connector.
They are different from the terminal symbols on the
front label.
*2) In case of use of an external power supply, input
voltage range is set from DC18V to 27V.
