A protocol converter between AutroFieldBus and PowerLoop. Consists of PowerLoop interface for power and communication, and AutroFieldBus interface towards AutroFieldBus driver (EAU-340). For hazardous areas, zone 1 and 2.
The unit is a PowerLoop driver card encapsulated in an EEx de encapsulation. It consists of a PowerLoop interface for power and communication, and an AutroFieldBus interface towards an AutroFieldBus driver.
The PowerLoop is a two-wire bus capable of delivering 30V DC/100W connected in ring topology and is galvanically isolated from the rest of the system, and interfaces detectors and other loop units including a 4-20 mA interface.
The AutroFieldBus address is set by switches. The AutroFieldBus is normally category 5 copper cable.
