SP/IO8 - 8-channel comprehensive module
The module has 8 comprehensive channels for analog input of unified voltage and current signals and 8 channels for analog output of current signals. Comprehensive SP/IO8 module can be applied for extending the number of channels of SP/V4 and SP/T6 modules by including more than one module into one protection contour with admissible decrease in fault-tolerance.
Thus, using SP/IO8 module is a compromise between the cost of the system and its fault-tolerance.
