PRZESTARZAŁY - Solenoida ML 24 V DTM / ATM

A magnetically latched (ML) solenoid is a bi-stable power switch that uses a magnetic latching mechanism to maintain its state (ON or OFF) without requiring continuous coil power supply. Its main advantages are:

Low current draw: It consumes very little current in steady state (less than 13 mA at 25°C), reducing battery drain.Reliability: Silver alloy contacts ensure reliable switching of live loads.Energy efficiency: Current draw is significant only during state change (less than 4 A for 20 ms).

This BLUE SEA solenoid is designed to operate with a nominal voltage of 24V DC. The maximum allowable contact circuit voltage is 32V DC.

This solenoid's current draw is very low. In steady state (ON or OFF), it is less than 13mA at 25°C. During state change (ON to OFF or vice versa), the draw is less than 4A for approximately 20 milliseconds.

Yes, this solenoid is IP66 certified. This means it is fully protected against dust and powerful water jets, making it suitable for demanding marine environments.

Silver alloy contacts provide high reliability for switching live loads. They ensure better conductivity and increased resistance to wear and corrosion, which is essential for durability and performance in high-current applications.

No, this specific model (PN 7719 / 7719B / 7719100) is a solenoid without a manual switch. The remote battery switch (RBS) models in the ML series with manual control are PN 7713 / 7717.

The solenoid has an LED output that allows remote indication of its state. A double-blinking LED ON-OFF may also signal a desynchronization between the remote command and the relay state.

This solenoid has a mechanical endurance of 100,000 cycles. Its hot-switching current capacity is 150A at 24V DC for 10,000 cycles.

This solenoid is CE certified and meets external ignition protection requirements per ISO 8846 and SAE J1171 standards. It is also rated IP66 for water and dust resistance.

It is recommended to install the solenoid as close as possible to the battery bank it is intended to control. This minimizes voltage drop and optimizes system performance.

For remote control of this solenoid, it is recommended to use a single-pole double-throw switch (SPDT) or a single-pole single-throw switch (SPST). An SPDT switch improves immunity to accidental switching if the switch terminals become wet.

The power terminals are 3/8"-16 (M10) tin-plated copper studs. The recommended maximum tightening torque for these studs is 15.8 N•m (140 in-lb) to ensure optimal and secure electrical connection.

Before starting the installation, it is imperative to disconnect all negative battery connections. Additionally, all unused control wires must be carefully isolated from each other and from any accidental contact, for example using heat-shrink tubing or electrical tape, to prevent malfunctions.

The terminals on this solenoid are designed for 3/8" (M10) ring terminals. The clearance for the terminal ring diameter is 1.18" (30 mm).

Recommended wire sizes depend on current:

For a continuous current of 225A: 2/0 AWG (70 mm²)
For a continuous current of 300A: 4/0 AWG (120 mm²)
For a continuous current of 500A: 2x 4/0 AWG (2x 120 mm²)
It is critical to select the appropriate wire size for the expected maximum load.

To prevent malfunctions, all unused control wires must be carefully insulated. External contact or a short circuit between control wires can cause unexpected behavior of the solenoid.

No, this solenoid (PN 7719 / 7719B / 7719100) is specifically designed for 24V DC electrical systems. Its control circuit requires a voltage between 18V DC and 32V DC.

This solenoid model is compatible with Deutsch DTM series connectors. Requirements for the mating side are a DTM-04-6P receptacle, WM-6P locking mechanism, 1060-20-0122 terminal pins, and 0413-204-2005 sealing plugs.

Yes, this ML series solenoid is designed to be used as a remote battery switch (RBS), allowing you to connect or disconnect a battery bank from a load, or to combine/isolate multiple battery banks.
