Preventa Safety Modules Time Delay Page 5 Type XPSTSW

5 Operating principle, references Preventa safety modules Type XPSTSW For safety time delays Operating principle Safety modules XPSTSW are used in applications requiring safety time delays: applications with a safety switchover contact (shunting contact in association with XPSVN modules for zero speed detection, solenoid valve monitoring, etc.). The time delay of safety circuits can be set to 16 preset values, using 2 selectors located on the front face of the modules. To aid diagnostics, the modules have LEDs which provide information on the monitoring circuit status and 2 solid-state outputs for signalling to the process PLC. In addition, their removable terminal blocks optimise machine maintenance.
