The ENP-DI10 M2 module has 10 universal digital inputs, each supporting dry/wet contact modes. Each input features an independent 32-bit pulse counter with persistent memory. The module is designed for connecting pulse meters, buttons, switches, and other devices.

The ENP-DI10 M2 module features a wired bus interface based on the Enapter Link protocol, enabling reliable communication with other modules. It also includes wireless Wi-Fi capabilities for secure data transmission and control via the Enapter Gateway and Enapter Cloud.

^* – The terminator is a resistor used at the ends of a differential data bus, to reduce signal reflections. The module has a built-in terminator, which can be enabled if the device is positioned at the end of the bus. However, in some cases, even if the device is at the end of the bus, enabling the terminator may degrade or disrupt communication. This depends on various factors, such as baud rate, line length, signal rise time, and the characteristics of connected third-party equipment, which cannot be predicted in advance.

General recommendation: Try enabling the terminator if communication is unstable. For short line lengths (less than one meter) and relatively low baud rates (such as 115200), enabling the terminator is likely unnecessary.

Module Overview

Dimensions

The dimensions are in mm and in brackets in inch.

Wired Connection Example

Here is an example connection where the sixth channel is used in dry contact mode, and the fifth channel is used in wet contact mode.

The module is connected to the Enapter Link bus alongside other Enapter modules. The Enapter Link bus requires terminators at both ends, which is built into the module and can be enabled via a DIP switch if the module is positioned at the end of the bus. (Note that while separate resistors are shown in the diagram, they should not be used if the internal terminator is enabled.)

Wireless Connection Example

Here you can find an example of a wireless connection, where the module is connected to the same digital inputs as in the previous example, where the sixth channel is used in dry contact mode, and the fifth channel is used in wet contact mode. However, unlike the wired Enapter Link connection, the setup and data exchange occur through a secure Wi-Fi network. For instructions on configuring the wireless connection, please refer to the Quick Start Guide.

Warnings

WARNING

• Alternating current voltage of 110 - 220 V is potentially lethal!

• All works on assembly and installation should be performed only with a disconnected power supply!

• The installation and assembly of device must be carried out by electrician in accordance with the applicable regulations.

Safety Instructions

WARNING

• This device must be mounted on a DIN rail in an electrical distribution enclosure accordingly with this manual to ensure protection against contact, water and dust.

• This device must not be used as part of safety-critical systems.

• Edge processing scripting should be used as a convenience feature for basic non-realtime automation and not for life-sustaining or safety-critical use cases. Normal operation depends on working internet, Wi-Fi, and Enapter Cloud. Enapter is not responsible for any harms or losses incurred as a result of any failed automation.
