ABB DI810 digital input module

Basic information

Product Model: DI810 (Digital Input Module)

System: ABB Ability ™  System 800xA ®

Article Number: 3BSE008508R1

Mechanical specifications: S800 series

Core functions and features

Channel configuration: 16 channels, supporting 24V DC input, using current sinking signal type.

Isolation design: 16 channels are divided into 2 groups (8 channels per group), and each group is isolated from the ground.

Protection and monitoring:

Each group is equipped with one process voltage monitoring input, and if the voltage disappears, an error signal can be fed back through the Modulus feedback channel.

The input circuit includes current limiting components and EMC protection components, and the sensor power supply can achieve current limiting through MTU.

Status indicator: The front is equipped with F (fault), R (operation), W (warning) indicator lights, and 16 channel "0"/"1" status indicator lights.

Precautions

Installation environment

It needs to be installed in a temperature environment of 0 to+55 ° C (certification range is+5 to+55 ° C), with a storage temperature of -40 to+70 ° C.

The relative humidity of the installation environment should be maintained between 5% and 95% and in a non condensing state, with a pollution level of 2 (in accordance with IEC 60664-1), while also meeting the G3 anti-corrosion level specified in ISA-S71.04.

When installed vertically in a compact MTU, the maximum ambient temperature is 40 ° C (104 ° F).

Mechanical Installation

This module belongs to the S800 series mechanical specifications and needs to be installed in compatible MTU models such as TU810, TU812, TU814, etc.

When installing, pay attention to the size of the module, which has a width of 45mm, a depth of 102mm (including 111mm connectors), and a height of 119mm. Adequate space should be reserved.

Wiring specifications

The maximum on-site cable length is 600 meters (656 yards), and the cable length needs to be controlled within this range during wiring.

The input voltage range is -30.+5V for the "0" state and 15.30V for the "1" state. When wiring, ensure that the input voltage meets this specification.

The input impedance of the module is 3.5k Ω, and impedance matching should be considered when wiring.

Isolation requirements

The 16 input channels of the module are divided into 2 groups, each with 8 channels. Each group is isolated from the ground, and care should be taken not to damage this isolation characteristic when wiring.

The rated insulation voltage of the module is 50V, and the dielectric test voltage is 500V AC. During the wiring process, it is necessary to avoid exceeding this insulation and test voltage.

Other precautions

The sensor power supply can be current limited through MTU, and the wiring should be set correctly according to the actual situation.

The key control code for the module is AA, and compatibility with related equipment must be ensured during wiring and installation
