1) In applications using encoders, 1L+ with reference 1M must always be connected
2) If this channel is not utilized, the associated auxiliary voltage must not be connected.
3) Terminals 19, 24, 47 and 48 (reference potential 2M) are connected together on the
Digital inputs The FM 453 provides four digital inputs per channel.
(I0 to I3)
All inputs are optocoupler inputs with equal priority and the reference poten-
tial 2M. Switching functions are allocated to an input number by way of ma-
chine data; input polarity is selected in the same way (starting and shutdown
slopes).
These fast inputs are PLC-compatible (24 V current-sourcing). Switches or
contactless sensors (2-wire or 3-wire sensors) can be connected.
Possible uses include:
