Requirements for Components of Third-party Suppliers
5.1.1
Socket Headers
The ESCON Module 50/4 EC-S’s implementation with pin headers permits mounting in two different
ways. The module can either be plugged onto a socket header (
Table 5-10) or be directly soldered to
a printed circuit board.
5.1.2
Supply Voltage
To protect the ESCON Module 50/4 EC-S, we recommend using an external circuit breaker, a TVS
diode, and a capacitor in the voltage supply cable. In this regard, please note the following recommen-
dations:

USE
(FU1)
An input fuse (FU1) is necessary in order to provide reverse polarity protection. Together with the TVS
diode (D1), this prevents current from flowing in the wrong direction.
TVS D
IODE
(D1)
To protect against overvoltage resulting from voltage transients or brake energy feedback, we recom-
mend connecting a TVS (transient voltage suppressor) diode (D1) to the voltage supply cable.
C
APACITOR
(C1)
The function of the ESCON Module 50/4 EC-S does not necessarily require the use of an external
capacitor (C1). To further reduce voltage ripple and feedback currents, an electrolytic capacitor can be
connected to the voltage supply cable.
