Siemens 3TX7014-1BM00 Interface Relay With No NC Contacts

Siemens 3TX7014-1BM00 is a plug-in interface relay that provides a single changeover contact (SPDT) in a compact 6.2 mm wide module. It is energized by a 24 V DC control coil and wired via screw terminals, designed to mate with Siemens 3TX interface blocks for dense, modular panel installation. The changeover contact includes a common terminal that swaps between normally closed and normally open states when the coil is energized, enabling simple interfacing of PLC outputs to field devices while preserving electrical isolation between control logic and the process side. This model is configured for a 24 V DC control environment and is intended for tasks such as signaling, interlocking, or driving small loads in compact automation architectures, where a single SPDT path suffices. As part of the 3TX family, it supports high-density mounting in control cabinets and provides a straightforward, plug-in solution for extending PLC I/O with a single, reliable switching path.
