Wiring the Inputs and Test Pulse Outputs
7-6 Operating Manual: PSS SB 3006-3 Series
Please ensure safety regulations and EMC guidelines are met!
Example: Dual-channel input devices, without test pulses
Features:
• This type of connection is mainly used for signal inputs with frequent
operation.
• The functionality of both input device channels should be monitored in
the application program via feasibility checks (see example in the
Programming Manual for the PSS-range).
• The possibility of a short circuit occurring between adjacent connector
terminals cannot be eliminated. For this reason, the two identical
(homogenous) channels on an input device must not be connected to
adjacent inputs.
• If you are using input devices with different (diverse) channels, adjacent
inputs may be used. Short circuits will be detected in the user program
via the feasibility check (see example in the Programming Manual).
