STG/8REL relay expansion board
The STG/8REL 8-relay expansion board converts the O/C outputs of the STG/OUT16S output
module into voltage-free exchange contacts. Up to two relay boards can be connected to
each output module. A relay board is directly connected to the output module (J1 connec-
tor) and a second relay board is connected to the former.
