AO845A Bidirectional Digital I/O Module

The AO845A is a reed relay contact (a-type) 4-channel output module with independent channels. Since the relays are independent of each other, each channel can be used with a different external power supply. The maximum rated output of each channel is 250VAC / 30VDC, 2A, with excellent immunity due to the relay isolation of the bus and output interfaces.

The AO845A is an electronic device designed for digital arithmetic operations in industrial environments. It employs a programmable memory for storing instructions within it to perform operations such as logical operations, sequential operations, timing, counting, and arithmetic operations, and is capable of controlling various types of machinery or production processes through digital or analogue inputs and outputs.

The AO845A has developed into a series of products of various sizes, including large, medium and small. Can be used in various scales of industrial control occasions, most of the modern PLC has a perfect data arithmetic ability, can be used in a variety of digital control areas. In recent years, PLC function units have emerged in large numbers, so that PLC penetrates into the position control, temperature control, CNC and other various industrial control. Together with the enhancement of PLC communication capability and the development of human-machine interface technology, it has become very easy to use PLC to form various control systems.
