TBX LEP030 Schneider Electric Communication Module

The Schneider Electric / Square D TBX DMS1625 is a distributed input/output base unit containing eight 24 VDC inputs and digital relay outputs. This base unit may be coupled with a compatible communications interface to form a complete distributed block, which is well suited for the control of discrete field devices located some distance from a host programmable logic controller (PLC). The application of distributed I/O blocks saves installation and maintenance cost, as compared to direct wiring of field devices to a centralized I/O system over long distances. The TBX DMS1625 base unit can be used with either SY/MAX® or Telemecanique PLCs, through the use of a compatible communications interface, or “top hat”. The interface mounts directly on the base unit, and allows the PLC to read and write to the I/O points through a suitable control network. The Class 8030 Type CRM275 Distributed Remote IO/NET™ Interface (DRIO) supports connection to the IO/NET control network as part of the PASSPORT™ I/O System. The TBX LEP020 and TBX LEP030 communications interfaces support connection to the FIPIO network. The TBX CBS010 Expansion Interface allows inexpensive connection of a second TBX base unit to a single communications top hat.
