It is a compact, grey rectangular device with a green terminal block on its upper side for connections. The label on the side indicates 'Legrand', 'EMDX-2 pulse output module', '4 120 59', 'CE', and 'For EMDX Premium Multi Measuring device'. It also states 'Made in Italy'.

2. Setup and Installation

The EMDX-2 Pulse Output Module is designed for straightforward installation within electrical panels or enclosures. It can be mounted either after a frame or directly onto a standard DIN rail profile.

2.1 Mounting

1. Power Off: Ensure all power to the electrical panel or system where the module will be installed is completely disconnected before beginning installation.
2. Select Location: Choose a suitable location within the panel that allows for proper ventilation and access to wiring.
3. DIN Rail Mounting: If using a DIN rail, simply clip the module onto the DIN rail until it securely locks into place.
4. Frame Mounting: If mounting after a frame, follow the specific instructions for your frame system to secure the module.

2.2 Wiring Connections

Connect the pulse output module to your EMDX Premium Multi Measuring device and the external system requiring pulse signals using appropriate wiring. Refer to the wiring diagram provided with your specific EMDX Premium Multi Measuring device for detailed connection points.

• Identify the two independent pulse outputs on the module.
• Connect the outputs to the corresponding inputs on your receiving system (e.g., PLC, data logger, energy management system).
• Ensure all connections are secure and comply with local electrical codes.

Warning: All electrical work should be performed by qualified personnel.

3. Operating Instructions

Once installed and wired correctly, the EMDX-2 Pulse Output Module operates automatically in conjunction with the connected EMDX Premium Multi Measuring device. The module converts the measured data from the primary device into electrical pulses, which can then be counted or interpreted by external systems.

3.1 Pulse Output Functionality

• Each pulse output corresponds to a specific quantity or event as configured in the EMDX Premium Multi Measuring device.
• The pulse rate and value per pulse are determined by the settings of the connected measuring device.
• The isolated outputs ensure electrical separation between the measuring device and the receiving system, enhancing safety and preventing interference.

For detailed information on configuring the pulse outputs (e.g., pulse weight, duration), refer to the user manual of your specific EMDX Premium Multi Measuring device.

4. Maintenance

The Legrand EMDX-2 Pulse Output Module is designed for long-term, maintenance-free operation. However, periodic checks can help ensure continued reliability.

• Visual Inspection: Periodically inspect the module and its connections for any signs of physical damage, loose wiring, or overheating.
• Cleaning: If necessary, gently clean the exterior of the module with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Connection Integrity: Ensure all terminal connections remain tight and secure.

Caution: Disconnect all power before performing any inspection or cleaning of the module.
