LANTIME M400

SKU: LANTIME M400

Rail Mount NTP Time Server with Meinberg reference receiver

The LANTIME M400 Time Server offers unparalleled flexibility and versatility and provides accurate time to your network in a compact and full-featured DIN railmount package for industrial applications such as power generation, transmission and distribution (substation automation), process control and industrial automation systems. The M400 includes an LC-Display and keypad and an extremely broad range of available options.

The LANTIME M400 is available with an integral receiver as well as an IRIG timecode reader and can be customized with a lot of different options to deliver exactly the feature set that is required for a certain application/environment.

Ultra-compact Form Factor

The ultra-compact form factor enables this product to become the ideal time and frequency source in installations where every millimetre counts. With up to 5 network ports, this NTP appliance offers the highest port density.

Simple System Configuration

As with most LANTIME M-Series models, a large LC-Display showing the state of the internal GPS receiver and the NTP/PTP subsystem is combined with three bicolour LEDs (green/red) that indicate the status of the three main components: Reference Time (e.g. GPS or GLONASS), Time Synchronisation Service (NTP/PTP) and Network (Link status). A fourth red LED is labelled ALARM and can be configured to signal any event that is covered by the notification handling routines.

Oscillator Options

The LANTIME M400 GPS is equipped with a high precision oscillator “TCXO” (look at oscillator options for details). The oscillator determines the holdover characteristics (e.g. when a reference source signal like GPS is disturbed or jammed). For applications with higher stability/holdover requirements, there are several oscillator options available (up to “OCXO HQ”).

Modular System Architecture

Because of its modular system architecture, it is possible to equip a LANTIME M400 time server with a number of different reference time sources. Optionally several additional frequency, serial string and pulse outputs are available as well as power supplies for additional input voltage ranges.

In addition to the standard electrical interfaces, a lot of output signals can be delivered on optical ports, too.
