Plug-in electronic railway voltage monitoring relay with four change-over contacts for reliable switching of very low currents (1 mA @ 5 VDC) up to currents of 10A @ 110VDC.<\/p>\n
The relay has optionally a delay on pull-in and\/or on drop- out. The delay time is adjustable with a lockable knob (either delay-on or delay-off, the other delay is fixed). The relay can also be supplied with fixed time delays (no knob). The pull-in voltage (Uon) and drop-out voltage (Uoff) are both adjustable via internal screws. The relay can also be supplied with a fixed pull-in and drop-out voltage. Suitable for monitoring DC voltages. The MTDV4-U200N offers a very small hysteresis (difference between pull-in and drop-out voltage). The relay is equipped with a LED which indicates the status of the relay contacts and activation of the time delay. Delay-off function for voltage drop up to 50% of minimum pull-in voltage, no auxiliary supply necessary. The built-in magnetic arc blow-out ensures adequate DC breaking capacity resulting in long contact life. The integrated contact separation prevents cross pollution of contacts. On the relay cover the serial number and data matrix code are shown for ease of traceability.<\/p>\n
The construction of the relay and choice of materials make the MTDV4-U200N relay suitable to withstand low and high temperatures, shock & vibrating and dry to humid environments. No external retaining clip needed as integrated \u2018snap-lock\u2019 will hold relay into socket under all circumstances and mounting directions.<\/p>","protected":false},"featured_media":2146,"template":"","meta":{"_acf_changed":false,"sku":"MTDV4-U200N","katanapim_id":"28972","external_key":"MTDV4-U200N","parent_external_id":"P-D Timer & Monitoring","grandparent_external_id":"GP-D platform","product_type_description":"ChildProduct","product_short_description":"Timer relay","product_long_description":"Plug-in electronic railway voltage monitoring relay with four change-over contacts for reliable switching of very low currents (1 mA @ 5 VDC) up to 10 A @ 110 VDC.

Relays play a vital role in reliable train operation. Key functions include galvanic isolation between control (computers\/PLCs) and power circuits, contact multiplication and amplification. Other features: predictable fail-safe behavior simplifying safety validation, long-term availability (no obsolescence), easy plug-in maintenance and EMI immunity. Ideal for hardwired, cyber-secure control systems used for signal transfer, safety interlocking, load switching and sub-system isolation.","product_features":"
