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.
General purpose 4-20 mA input unit for third party detectors.
Analogue values supported.
Faults, alarms and warnings supported.
Short-circuit isolator on PowerLoop.
Conforms to CE standards
Maritime / offshore environment type approval
