HATLAPA BCS‑03 Timing‑Sequence Control Relay Module

Brand: HATLAPA (Germany)

Main Unit Model: BCS‑03

Part Number: 316547‑04702

Product Background

HATLAPA is a well‑established German marine equipment manufacturer, specializing in marine deck machinery including ship windlasses, mooring winches and mooring systems. It also develops in‑house electronic control modules for winch logic management.

BCS‑03 is an original‑equipment dedicated fixed timing‑sequence control module. It is not an off‑the‑shelf general‑purpose time relay; it is an OEM spare part for HATLAPA winch control systems.

• Part No. 316547‑04702: Order reference number for shipyards and spare‑part supply chain.
• BCS‑03: Physical hardware unit model.
• Mounting: Standard DIN‑rail clip‑on installation, commonly fitted inside deck electrical cabinets of ocean‑going cargo vessels, oil tankers and bulk carriers.
• Power rating: AC230V ±10%, AC/DC compatible; max output current 4A. Three hardware‑fixed timing delays inside unit: 0.4 s, 0.6 s, 0.8 s. Delay values are hardware‑burnt and cannot be adjusted on‑site.

HATLAPA BCS‑03

Model Breakdown

1. HATLAPA: Original equipment brand, German marine deck‑machinery manufacturer
2. BCS‑03: Unit model. B = Bridge Control System; CS = Control Sequence; 03 = hardware revision
3. 316547‑04702: Spare‑part number for procurement, customs declaration and material management

Main Functions

1. Hardware‑fixed timing‑sequence output Three preset fixed delays: T‑T1=0.4 sec, T‑T2=0.6 sec, T‑‑‑=0.8 sec. Upon receiving trigger input signal, relay contacts activate sequentially per pre‑set time intervals. Timing parameters are fixed at factory and cannot be reprogrammed locally.
2. Relay contact output Maximum output current 4A, passive relay contacts for driving contactors and solenoid coils.
3. AC/DC universal power supply Nominal operating power AC230V ±10%, C‑DC AC‑DC compatible, tolerates voltage fluctuation typical for shipboard power networks.
4. Sequential logic control Receives IN input signal and switches OUT output circuit in timed sequence to stagger load activation and prevent inrush surge caused by simultaneous startup of multiple loads.
5. DIN‑rail mounting Standard DIN‑rail form factor for direct installation inside marine deck control cabinets. More products: www.plcva.com

Note: Delay time values cannot be modified by end‑user. Three timings are hardware‑fixed without keypad programming support.

Applications

1. HATLAPA marine windlass & mooring winches (primary use) Deployed within control systems for ship mooring winches and anchor windlasses. It governs timing sequence for winch motor commutation, brake release and clutch engagement. The 0.4 s / 0.6 s /0.8 s fixed delays stagger mechanical actions to avoid mechanical shock and electrical short‑circuit risks.
2. Deck electrical control systems for ocean‑going merchant vessels Special‑purpose spare part fitted inside HATLAPA deck‑machinery cabinets for bulk carriers, oil tankers, container ships and offshore vessels.
3. Restricted for HATLAPA original winch systems. Rarely applied to third‑party equipment; it is an OEM dedicated module rather than general‑purpose time relay.
