Digital Modules SMART I/O User’s Manual

Surface-Mounted Devices (SMDs) are used in the production of SM-ACI1 modules. The components to be changed, marked with an asterisk in figure 4-5, need not necessarily be SMDs. Please, refer to the board overview figure (solder side, figure 4-

3) for the approximate position of the jumpers. Notice should be taken of the fact, that when calculating component values for a specific filter, the capacitor/resistor relationship is almost linear. For this purpose, it is suggested that only the capacitor be changed. Hence, for a doubling of the filter frequency input, the value of the capacitor should be reduced by half.

In the following, the pinout/signal relationship for the SM-ACI1, when connected to a particular screw terminal block, is shown.

WARNING!

Dangerous voltages are present at the terminals.
