## Summary description

The ALLNET 101240 is a compact device with dimensions of 34.4 mm width, 27 mm depth, and 28 mm height. It is certified with CE and RoHS, ensuring compliance with safety and environmental standards. This model is designed for efficient performance and reliability, making it a suitable choice for various applications.

## Long description

The ALLNET 101240 ALLNET ALL3688 is a compact D0 sensor designed to interface with ALL3691/3692 power meters and to capture the D0 optical pulse signal emitted by modern energy meters. The device detects the infrared D0 pulses — typically transmitted by utility meters at approximately two-second intervals — and mounts to the meter body using an included magnetic ring. It is CE and RoHS certified and measures 34.4 mm (W) × 27 mm (D) × 28 mm (H), making it suitable for installations where a small form factor is required.
Advantages
The ALLNET D0 read head provides a reliable method to remove and read the D0 signal from compatible power meters without modifying the meter. Its magnetic mounting simplifies installation and ensures stable positioning on the meter housing. Compact dimensions and regulatory certifications (CE, RoHS) support safe and space-efficient use in residential or commercial metering setups.
Suitable for
Reading D0 infrared pulse output from ALL3691 and ALL3692 energy meters
Data collection and integration with monitoring equipment that accepts D0 input
Retrofit applications where a non-invasive optical sensor is required
Key specifications
Model: ALLNET 101240 (ALLNET ALL3688)
Compatible meters: ALL3691 / ALL3692
Dimensions: 34.4 × 27 × 28 mm (W × D × H)
Interface: optical D0 (infrared) read head
Mounting: magnetic ring
Certifications: CE, RoHS
How to use
Place the D0 read head on the meter display area where the D0 infrared emitter is located and secure it with the magnetic ring so the sensor window faces the meter’s IR output. Connect the read head to the receiving or logging equipment according to the equipment’s interface requirements. Verify that the receiving device is configured to sample the D0 pulses; the meter typically transmits pulses at roughly two-second intervals. Check alignment and signal reception after installation to confirm reliable pulse detection.
Usage recommendations
Ensure the sensor window is clean and unobstructed and avoid placing the read head where strong ambient infrared sources may interfere. Periodically verify that the magnetic mount remains secure and that the receiving device correctly interprets the D0 pulse rate.
