Product Description
Digital slave input module:
Such modules are commonly used in industrial automation systems to receive digital signals from field devices such as sensors, switches, etc.
They typically have multiple input channels, each of which can be connected to a field device.
These modules can convert the signal of the field equipment into a digital signal that can be recognized by the system and transmitted to the master controller or the host computer for processing.
General features:
These modules often have isolation features to prevent high voltage or interfering signals from field equipment from affecting the system.
They may have configurable input parameters such as input ranges, thresholds, and so on.
The module usually communicates with the host controller or the host computer through some communication protocol (such as RS-485, EtherNet/IP, Profinet, etc.).
In industrial automation systems, common communication protocols include but are not limited to the following:
RS-485: A serial communication protocol commonly used in industrial automation systems to support communication between multiple nodes.
EtherNet/IP: Ethernet-based communication protocol developed by ODVA (Open Device Network Vendors Association) for industrial automation systems.
Profinet: Ethernet communication protocol standardized by PI (Profinet International) for the field of industrial automation.
Modbus: A general purpose serial communication protocol, originally developed by Modicon and now widely used in industrial automation systems.
CANopen: Communication protocol based on CAN (Controller Local Area Network) for embedded network control.
PROFIBUS: A fieldbus standard for automation systems, widely used especially in Europe.
DeviceNet: CAN-based communication protocol developed by ODVA for industrial automation systems.
EtherCAT: An Ethernet fieldbus system that is especially suitable for applications requiring high-speed data communication.
