The Autronica 116-BN342-2 4-20mA Input Unit, is a general purpose PowerLoop interface, designed to connect third party detectors to the AutroSafe Fire and Gas Sytem. The Autronica BN-342/2 is a two-wire power and signalling bus connected in topology and is galvanically isolated from the rest of the system.
The BN-342/2 communicates with the AutroSafe system via the PowerLoop protocol. The Autronica BN-342/2 has a 24VDC/400mA supply output (galvanically isolated from the PowerLoop) providing power to the connected detectors, plus a 4-20mA input galvanically isolated from the PowerLoop.
