DX581-S safety digital input/output module > Mounting, dimensions and electrical connection
The terminals 1.8, 2.8, 3.8 and 4.8 as well as 1.9, 2.9, 3.9 and 4.9 are electrically intercon-
nected within the I/O terminal unit and have always the same assignment, independent of the
inserted module:
● Terminals 1.8, 2.8, 3.8 and 4.8: Process voltage UP = +24 V DC
● Terminals 1.9, 2.9, 3.9 and 4.9: Process voltage ZP = 0 V
