5.3.3 PCD3.A220, 6 relay contacts, type “NO”, w/o contact protection
Application
The module contains 6 relays with normally-open contacts for direct or alternating
current up to 2 A, 250 VAC. It is especially suited wherever perfectly isolated AC
switching circuits must be controlled with infrequent switching. On this module there
is no contact protection available. There are two groups of three relay contacts, which
have one common terminal (see output diagram).
