Hien Electric HI-NET(R) HN-1002 32-Channel Marine Contact Multiplexer | Class NK Certified
₨ 250,000
Genuine Hien Electric HI-NET(R) 32-Channel Remote Contact Transmission Multiplexer (Model: HN-1002). Engineered for critical shipboard automation and marine control telemetry, this high-grade distribution block handles up to 32 independent channels (CH1 through CH32) of discrete dry-contact data signals. Features integrated error diagnostics, dedicated grounding (FG), and standard alternating current power wiring terminals (AC IN), fully certified under Class NK registry requirements for marine engine and hull electronics.
Hien Electric HI-NET(R) HN-1002 32-Channel Marine Signal Multiplexer
Streamline your onboard vessel wiring architecture and optimize telemetry safety loops with the Hien Electric HI-NET(R) HN-1002 Contact Multiplexer. Purpose-built by Hien Electric Industries in Japan, this industrial-grade remote terminal interface consolidates massive bundles of individual alarm, sensor, and switchgear wires down into a unified communication stream, drastically cutting down installation complexity and physical line weight.
The rugged metal chassis houses a pair of heavy-duty, double-row barrier screw terminal strips. These arrays map out 32 distinct data channels (CH1 to CH16 on top, and CH17 to CH32 on the lower deck). The front interface includes dual vertical tracking window cutouts embedded with status indicator lights, letting shipboard technicians visually track active data packets, channel actuation, or network loop disruptions (ERROR) instantly.
