METSO has produced a series of controller modules, including models D201189L, D201126L, D201129L, and D201190L, which are widely used in the fields of industrial automation and process control. The following is a detailed introduction to these controllers:

D201189L Input/Output Module
D201189L is a high-performance input/output (I/O) module primarily used in the fields of industrial automation and process control. It can receive signals from other devices and convert them into recognizable analog or digital signals, as well as convert analog or digital signals into signals recognizable by other devices. This module has the characteristics of high precision, fast response, and stable reliability, and is suitable for various industrial environments.

D201126L digital input unit
The D201126L digital input unit is mainly used to receive external digital signals, which usually come from devices such as switches, buttons, limit switches, proximity switches, etc., with only two states: on and off. After receiving these signals, the digital input unit will transmit them to the central processing unit for further processing. This module supports serial communication, enabling data transmission between computers and other devices, or connecting to various sensors to collect data from the external environment.

D201129L digital output unit
The D201129L digital output unit is mainly used to send control signals, which are usually used to drive devices such as actuators and relays. This module has 8 output channels, each of which can be independently configured to meet different control requirements. The D201129L digital output unit also has a 200mA PNP output characteristic, suitable for applications that require high current driving.

D201190L controller
D201190L is a high-performance embedded industrial controller suitable for various industrial automation and process control applications. This controller has powerful processing capabilities and rich peripheral interfaces, which can meet the needs of different application scenarios. The D201190L controller also features a low-power design that can be selected according to actual needs to extend the battery life of the device.
