Between outputs this interface module have a protective
separation
The system side ( rack including 24V power supply ) have a protective
separation from touch dangerous voltage to the process side ( 8 output
signals ).
Between outputs they have only an electrical isolation.
The output signals on the process side only have an electrically (
galvanically ) isolation between each other. A mix with safety small
voltage and touch dangerous voltage is not allowed.
The SIMADYN D-side power supply is displayed using a green LED (P).
The SIMADYN D-side power supply (1P, 1M) is short-circuited (fault
condition).
The SIMADYN D power supply is available at the double test socket X5
(G; +):
Double test socket X5
+ (1P of X3)
G (1M of X3)
The status of the 8 signals is displayed using a yellow LED for each of
the signals (1...8).
There are three screw connections on terminal strip X2 for each signal to
the plant/system side:
• terminals 14, 24 ... up to 84 for NO contact
• terminals 12, 22 ... up to 82 for NC contact
• terminals 11, 21 ... up to 81 as center contact
The relay contact connections are determined as follows:
Quiescent state
Contact closed (NC contact)
Contact open (NO contact
1)
n: 1...8 depending on the channel No.
To connect the power supply see "User manual FM 458-1 DP" chapter
"Installation and EMC guideline".
