![]() ![]() Relays are ideal to use in trains for signal transfer/repeat, safety interlocking functions (brake - doors), load on-off switching and sub-system isolation. Using these features, one can build a hardwired, fail-safe control system which is cyber secure and insensitive to electromagnetic disturbances and surges. You can adjust specific ones by using their GUID, or switching to them prior to running these commands. Note that these commands adjust the currently active power profile. unlike more sensitive electronics, relays are insensitive to EMI You must run this utility with elevated rights, so be sure to open an elevated console window by right-clicking ‘cmd.exe’ and selecting ‘Run as Administrator’.easy maintenance by plug-in feature and transparent cover.long term availability (no obsolescence).predictable failure behavior (Fail Safe) making system safety validation more simple than using computer based solutions like PLC’s.Key functions are galvanic isolation between control (computers/ PLC’s) and power circuits providing system isolation, contact multiplication and amplification. Relays continue to play a vital role in reliable train operation. The WDE4-U200N is used in demanding rolling stock applications where one pulse in output is necessary after activating the relay. Optional version with an energy saving of more than 50 % and contact configuration 2 C/O + 2 N/O contacts. Because it may take some time for Cisco to issue the. Compact design, choice of many options and a wide range of sockets makes the WDE4-U200N relay an easy and flexible solution to use. This activation key is free from Cisco and required for PDM functionality. No external retaining clip needed, as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting orientations. The construction of the relay and choice of materials makes the WDE4-U200N relay suitable to withstand low and high temperatures, shock & vibration and dry to humid environments. On the relay cover, the serial number and data matrix code are shown for ease of traceability. The integrated contact separation prevents cross pollution of contacts. The built-in magnetic arc blow-out ensures adequate DC breaking capacity resulting in long contact life. The relay is equipped with two LEDs which indicate the presence of power supply and the energizing of the coil. The relay can also be supplied with a fixed pulse time (no knob). The pulse time is adjustable with a lockable knob. When the relay is activated, the coil is energized with one pulse. Plug-in electronic railway timer relay with four change-over contacts for reliable switching of very low currents (1 mA 5 VDC) up to currents of 10A 110VDC. Timer Utility is an all purpose time management tool consisting of multiple alarms, countdown timers, date countdowns, stopwatches and an all new Time Tracking feature.
