KISSLING BI-STABLE RELAYS WITH INTERNAL CONTROL ELECTRONICS Series 31 / SAFETY - from TE Connectivity (TE) Our series 31 bi-stable power relay with internal control electronics is based on the Series 30 industrial relay and has all of the same quality mechanical and electrical switching characteristics - but also features additional electronic functions. This relay is particularly well suited for battery management and power distribution applications on commercial vehicles, buses, construction & agricultural vehicles, ground support equipment and lift trucks. The robust design of our bi-stable relays provides a sealing rate of IP67 and IP6K9K (steam pressure cleaning) in accordance with IEC 60529 and DIN 40050-9. The series 31 includes power relays in nominal volt- Features ages of 12 & 24 V and nominal continuous amperages of 300 Amps. Sealed housing conforms to IP6K9K Contact voltages up to 250VDC with magentical blowout (>40VDC). Robust design Elektronic Safety-Control Variety of configuration options 6G shock and 4G vibration resistant The technical principle of this relay is a reliability proven two coil device with a Pull In and Drop Out coil with a powerless permanent magnetic Applications holding. Commercial vehicles An impulse into the respective coil switches the relay into an On or Bus Off position. The electronic function protects against incorrect actu- Lift truck ation which therefore prevents overheating or damage to any compo- Ground support equipment nent parts. Construction and agricultural vehicles The minimum pick up impulse time is approximately 250ms and contin- uous signals will not cause any damage. The electronic board integrates under voltage function that eliminates critical mechanic actuation, a suppression diodes, short circuit and po- larity protection.
