General Purpose Input Output
General-purpose input/output (GPIO) is an input/output card with core microcontroller design. It is incorporated with various type of inputs such as pure contact, voltage (dc) and voltage (ac). GIO supports on board open collector and relay contact outputs for the users ease to adept into various applications. All the inputs and outs are optically isolated and extra protection against thunderstorm is incorporated. 12 inputs and 12 outputs in a single package makes it stand out yet you can have cascading to acquire more inputs and outputs. It combines multimode communication interfaces such as RS-422, RS-485 and RS-232 in addition to other features.
