OV141 series relays can be applied for railway diesel locomotives, subway rolling stocks, EMU (electronic multiple units), DMU (diesel multiple units) and other industrial electric automation control equipment. Such DC contactors are used to control circuit in locomotives and rolling stocks.

The production standards comply with GB/T 21413.1-2008/IEC 60077-1:1999; GB/T 21413.2-2008/IEC 60077-2:1999; and TB/T 1510-1993.

Such relays have the following features: module structure; small volume; and light weight. Magnetic coil ends of such relays are equipped with voltage suppressor which can inhibit the self-induced electromotive force of the coil. Working indicator light is equipped to show the working status of the relay. Due to advanced contact module, auxiliary contact has fast-moving, self-cleaning and sealing characteristics.

Models Selection

1. Coil control voltage of OV141 series relays can be DC 24V, 48V, 74V and 110V, and coil working voltage is between 80% and 110%.

2. External wiring mode is below:

Coil Wiring: M4 Screw

Contact Wiring: M3 Screw

3. Contacts of OV141 relays can be combined within the range of (5NO + 5NC).

4. Fast-moving switch OV867W2A2b (Protection Class is IP60) should be used as contact when relays are applied in windy and sandy arears.

5. When voltage suppressor is parallel connected to two ends of coil, wiring should be as per polarity signs.
