Overview

Essential details：DSDO120  57160001-AK Digital input board ABB

Digital input (DI) modules are available for programmable logic controllers (PLCS) and Motor drive to receive 24V numbers from field sensors and switches Enter. The isolation function manages the grounding potential difference. Use electricity with hysteresis
The voltage comparator converts the input signal to a logical high or low level. simultaneously Implement some form of current restriction to avoid overdoing the 24V input Current consumption of; Power loss is in the compact high density multi – channel design A key question.
The IEC 61131-2 standard for programmable controllers specifies three types Different types of digital input receivers: Class 1, Class 2 and Class 3. Category 3
The ideal implementation scheme is: consume as close as possible in the open state 2mA current, voltage conversion threshold between 5V to 11V.

Digital input and output module (I/O module) is the key component of each PLC (programmable logic controller). Specifically, they undertake the control, communication and actuating functions of the PLC. But digital I/O modules face increasing challenges. These challenges arise from the growing need for flexible usage and a concurrent fierce battle for market share in system reliability.

Changing customer needs are also a factor. The IP protection and access restriction of the solution as well as its power consumption and system lifetime play a decisive role in the battle for customers. Security is also becoming more important, especially in controlling drives. In today’s competitive market, long experience is essential, as are features such as simplicity, low maintenance costs, and secure data access.
