Interfaces
4.8 I/O interface
Signal type
DI - digital input (24 V signal)
DO - digital output (24 V signal)
K - switching contact
VI - voltage input
The 24 V power supply is to be designed as functional extra-low voltage with protective
separation in accordance with EN60204-1, Section 6.4, PELV (with G ground).
Note
The connecting cable between the voltage source and the load current supply connector L+
and the associated reference potential M should not exceed a maximum length of 10 m.
Digital inputs (onboard)
The SIMOTION C has 18 digital inputs. These can also be interconnected via symbolic
assignment using variables as of SIMOTION V4.2 for C240 and C240 PN.
Switches or proximity encoders (2- or 3-wire encoders) can be connected. Addresses are
allocated in the hardware configuration.
The digital inputs can be used as:
● User-addressable process inputs (I0 to I11). The inputs are subject to a signal delay (see
Technical data (Page 163)) and are sampled in a cycle of 125 μs.
