Field Terminals

Field terminals provide the connection between the I/O module and field wiring. They include optional fuses and circuit breakers. Mechanical keying systems prevent misconnection of I/O modules by the type of field terminals. Field terminals are mounted on the module base plate, one for each I/O module. These terminals are securely clamped to the I/O module and form a highly integrated electrical and mechanical assembly. Field terminals can be replaced during operation without removing the base plate and without interfering with the operation of other modules.

Base Plate

Mounted on flat or T or G DIN rails, base plates form the physical and electrical backbone of the 8000. supporting and connecting bus interface modules, power supplies, I/O modules, and field terminals, and supporting the internal Railbus address, data, and power lines. They provide terminals for LAN and field wiring shielded cables and can distribute bus field power to I/O modules. The I/O module backplane can support 4 or 8 I/O modules.

Power Supplies

Good power management is at the heart of a truly distributed I/O system. 8000 power supplies receive local unregulated power and then provide regulated power to the bus interface modules and I/O modules. Power redundancy is supported.

Bus Interface Module (BIM)

The BIM provides a serial data connection to a host controller, which can be a distributed control system (DCS), a programmable logic controller (PLC), or a PC running a software control package. with the BIM, you can adapt to the most common fieldbus protocols. At the same time, the BIM uses a fast internal bus for data transfer to I/O modules. You can control up to 32 I/O modules with just one BIM per node.
