The Switch/Proximity Detector Repeater D5231 is a module suitable for applications requiring SIL 2 level in safety related systems for high-risk industries. With 8 channels, it offers one of the highest packing densities of any intrinsically safe isolator on the market. The unit can be configured for switches or proximity detectors, located in Hazardous Area, and repeats the input state to a solid-state relay contact in Safe Area. The selectable fault detection circuit is available for proximity sensors or switches equipped with end of line resistors. The module is fully configurable to achieve input/output multiplexing, duplication, inversion, and input logical elaboration (AND, OR). Each output can also be configured to report the cumulative fault of any input subset. Configuration and diagnostic parameters are programmable and can also be monitored/set through Modbus.
