Pepperl+Fuchs LB7x04A remote I/O module

The LB remote I/O system is designed for minimal wiring. Zone 2/Division 2 field mounting, in addition to a single bus line between the remote I/O system and the control room, is said to drastically reduce wiring requirements. Another advantage is that, because of its compact size, it can be used in systems with little free space .

The universal LB7x04A module can be used as an analog input for supplying 2-wire transmitters, an analog output for operating proportional valves, I/P converters or on-site displays, a digital input for reading contacts, or a digital output for operating valves and sensors or LEDs. Each of the four channels can be parameterised independently of one another when using the module in this way. The status of each channel can be read from an LED. The module status is indicated by additional LEDs. When the universal module is exchanged, the replacement module always takes on the parameter settings of the original module, preventing errors when replacing modules.
