I/O modules and I/O terminal blocks may only be plugged in and removed when the Saia PCD® and the external +24V are disconnected from the power supply.The Annex, Section A.3 "Relay contacts" contains measurement details and suggested wiring for the relay contacts. For safe switching and a long service life, these figures must be observed.6-31PCD3.A2006.5.1PCD3.A200, 4 relays with make contacts, with contact protectionApplicationThe module contains 4 relays with normally-open contacts for direct or alternating current up to 2 A, 250 VAC. The contacts are protected by a varistor and an RC element. The module is especially suited wherever perfectly isolated AC switching circuits with infrequent switching have to be controlled.Technical dataNumber of outputs:4, electrically isolated make contactsType of relay (typical):RE 03 0024, SCHRACKSwitching capacity: (contact lifetime)2A, 250 VAC AC1 0.7 x 106 operations 1 A, 250 VAC AC11 2 A, 50 VDC DC11 1 A, 24 VDC DC11
