The ABB CL-LER.18AC2 Logic Relay (part number 1SVR440723R0000) is a compact programmable logic relay designed for industrial and marine control applications. With 12 AC inputs and 6 relay outputs, it serves as a reliable building block in vessel automation panels, machinery control cabinets, and auxiliary system switchboards. Its wide supply voltage range (AC 85–264V, 50/60Hz) makes it well suited to the variable power conditions encountered in marine environments, reducing the risk of control failures caused by voltage fluctuations onboard.
Key Features
✓ 12 AC digital inputs for high-density signal monitoring in control panel applications
✓ 6 relay outputs rated at 8A — capable of switching loads up to 10A at 240V AC (B300) or 8A at 24V DC (R300)
✓ Wide input voltage range: AC 85–264V, 50/60Hz — compatible with international shipboard power standards
✓ Low power consumption at 10VA — suitable for panel mounting in space-constrained marine enclosures
✓ Secure terminal connections: tightening torque 0.6Nm, AWG 28–14 wire range for reliable wiring integrity in vibration-prone environments
Marine Applications
Automation and interlocking logic in engine room control panels
Auxiliary machinery sequencing and alarm relay functions
Pump control, valve actuation, and fan starter logic circuits
Switchboard auxiliary relay and monitoring duties
Retrofit and upgrade of legacy relay-based control systems with compact programmable logic
Why Marine Engineers Choose ABB CL-LER.18AC2
ABB’s CL-LER series is widely deployed in marine and offshore control systems for its robust relay output ratings, broad voltage tolerance, and straightforward integration into existing ABB and third-party automation architectures. The combination of generous I/O count in a compact form factor reduces panel space requirements without sacrificing control flexibility.
