STG/8REL relay expansion board
The STG/8REL 8-relay expansion board converts STG/OUT16-S O/C outputs into voltage free
changeover contact. Up to two relay boards can be connected to each output module. A relay
board is directly connected to the output module (J1 connector) and a second relay board is
connected to the first.

STG/IN8-PK and STG/OUT16-S module addressing
STG/IN8-PK and STG/OUT16-S modules are addressed using the two rotary switches
in RSW 1 and 2 hexadecimals. Rotary switches permit hexadecimal settings (base 16).
Each switch as 16 positions (0-F) and the pointer is positioned on the number chosen
using a screwdriver to create a decimal value between 1 and 255 (see table 1).
For the maximum number of modules, see the table at par. 3.1.
Each module must have univocal address in the system. Dual addresses are not
permitted even if modules are on different serial buses.
