Description

ABB DI885 3BSE013088R1

Digital Input (DI) modules are available for programmable logic controllers (PLCS) and motor drives to receive 24V digital inputs from field sensors and switches. The isolation function is used to manage the grounding potential difference. A voltage comparator with hysteresis is used to convert the input signal to a logical high or low level. At the same time, some form of current limiting is implemented to avoid excessive current consumption from 24V inputs; Power loss is a key problem in compact high density multichannel design.

The IEC 61131-2 standard for programmable controllers specifies three different types of digital input receivers: Class 1, Class 2 and Class 3. The ideal embodiment of Class 3 is to consume as close to 2mA as possible in the switched on state, with a voltage conversion threshold between 5V and 11V.

PLC digital and analog input module difference

One: PLC analog input module (analog input module), also known as A/D module, converts the continuous analog signal generated by the sensor detection in the field into the digital quantity that the PLC CPU can receive, generally 12-bit binary number, the more digital quantity modules, the higher the resolution.

Two: PLC analog output module. The analog output module, also known as D/A module, converts the digital quantity sent by the PLC CPU to the analog output module into the analog quantity (voltage or current) that can be received by the external device. The digital signal received by the analog output module is generally 12-bit binary number, and the more digital quantity modules, the higher the resolution. The digital module is to detect the state of the external switching input.

Three: Digital input and output signal is the switching signal, 0 or 1, analog signal, there are two, voltage or current signal, generally the signal transmitted by the transmitter, such as the pressure transformer to detect the pressure of the water pipe, it will output an analog signal 4-20ma or 0-10V signal to the PLC, PLC for data processing, This is the difference between a digital input module and an analog input module.
