SCADA I/O modules

In computing, input/output, or I/O, refers to the communication between an information processing system (such as a computer), and the outside world, possibly a human, or another information processing system. Inputs are the signals or data received by the system, and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. I/O devices are used by a person (or other system) to communicate with a computer. For instance, a keyboard or a mouse may be an input device for a computer, while monitors and printers are considered output devices for a computer. Devices for communication between computers, such as modems and network cards, typically serve for both input and output.

SCADA I/O modules are devices that are Input / Output to a SCADA. Inputs are Temperature, Pressure, Flow rate, Humidity, Level etc called as Analog Inputs. Inputs from Flow switches, level switches, Pressure switches, Proximity switches, Limit switches, auxiliary contact of contactor etc are called Digital Inputs. Outputs are analog signals like 4-20mA or 0 to 10VDC or digital signals like pulse output, relay output etc.

Scan Electronic Systems provides variety of Analog and digital I/O modules with SCADA connectivity through RS232, RS485 and Ethernet with Modbus RTU and Modbus TCP protocols which are the most popularly used protocols in Industry.
