Simatic Rf600 - Siemens SIMATIC RF600 System Manual

Output Outport (0), (1), (2), (3)
● Each output is rated for 0.5 A current and is electronically protected.
● Four digital outputs can be operated simultaneously with up to 0.5 A each (up to 1.5 A in
total).
● The outputs are optically isolated through optocouplers.
Input Inport (0), (1), (2), (3)
● The inputs are optically isolated through optocouplers.
● The 24 V voltage for the digital inputs (e.g. switches, proximity switches) must be supplied
over a separate cable if electrical isolation is required.
● Level Low 0 ... 3 V; High 3,6 ... 24 V
● Sampling rate < 20 ms
The following diagrams illustrate various connection possibilities.
Voltage infeed through internal source (no electrical isolation)

Alternative connection possibilities:
● Pin 2 (VCC) to Pin 9 DI Common
● Pin 1 GND to busbar inputs
