IO-RU-7 Distributed I/O:s ? Cost-efficient I/O expansion for EXO controllers ? I/O distribution via RS485 ? Off-line functions in case of communication loss Small distributed I/O module for expansion of Regin’s programmable EXOflex and EXOcompact controllers. Can be adressed and communicate via EXOline. ? Can handle pulses on inputs and outputs ? Built-in temperature sensor ? Special condensation input available IO-RU-7 enables quick and easy expansion of a system by 4 additional inputs and 3 additional outputs per controller. Communication takes place via EXOline. Inputs The I/O module has one analogue and one universal input, which both support PT1000. One of the two digital inputs can be used as a condensation input by configuring a DIP switch. One additional analogue input is available and is used for the internal temperature sensor. Outputs All digital outputs can handle pulses, including the universal outputs when set as digital. Configuration IO-RU-7 must be configured by a competent systems integrator knowledgeable in the use of EXOdesigner. It is configured either by adapting the standard I/O function or by writing new program code using EXOL. DIP switches In IO-RU-7, only DIP switch 4 has any function. For all other DIP switches, the position of the switch has no effect on the functionality of the unit.
