With an open relay contact, the current leakage through the contact protection is 0.7 mA (at 230 V / 50 Hz). This should be taken into account for smaller AC loads. If this is too high, it is recommended to use a PCD3.A220 module (without contact protection).Watchdog: This module can be used on all base addresses; there is no interaction with the watchdog on the CPUs.6-33PCD3.A2106.5.2PCD3.A210, 4 relays with break contacts, with contact protectionApplicationThe module contains 4 relays with normally-closed contacts for direct or alternating current up to 2 A, 250 VAC. The contacts are protected by a varistor. 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 break contactsType of relay (typical):RE 01 4024, SCHRACKSwitching capacity: (contact lifetime)2 A, 250 VAC AC1 1 A, 250 VAC AC11 2 A, 50 VDC DC11 1 A, 24 VDC DC11
