Terminal modules
9.5 Terminal modules TM-EM/EM 60S and TM-EM/EM 60C
3. In additional, an ET 200iSP station which is built exclusively with black terminals may not
be operated without a RS 485-iS coupler.
The RS 485-iS coupler not only performs the function of ensuring explosion protection by
providing an intrinsically safe PROFIBUS signal, it also provides the required bus
impedance that is required by ET 200iSP stations for the operation.
4. Only the blue PROFIBUS connector with order number 6ES7972-0DA60-0XA0 ensures
the correct bus impedances or bus connections in the system.
Properties
● Terminal module for 2 electronic modules
● Connection of actuators and sensors by means of screw terminals for TM-EM/EM 60S
● Connection of actuators and sensors by means of spring terminals for TM-EM/EM 60C
● Self-generating interference leakage from the terminal module to the mounting rail by
means of a spring contact
● Prewiring of the terminal module is possible
