5.3.1 PCD3.A200, 4 relay contacts, type “NO”, with contact protection
Application
The module contains 4 relays with normally-open contacts for direct or alternating
current up to 2 A, 250 VAC.The relay contacts are protected by a varistor and an RC
element. The module is especially suited wherever perfectly isolated AC switching
circuits must be controlled with infrequent switching.
