About Siemens 3TX7005-3AC03 Interface Relay, Narrow
Interface modules are available either with relays or semiconductors. Semiconductor interfaces offer some significant advantages: The electronic components are extremely reliable and have an extremely long service life (refer to the diagram below). The input interface combines the best of both worlds - improved technical features and a lower price. When considering output interfaces, the question of "relay or semiconductor" needs to be taken into account as well as the making/breaking capacity and the number of operating cycles. If a relay has to be replaced just once during the complete lifetime of a machine, then a semiconductor interface will already have paid for itself.
