KISSLING BI-STABLE RELAYS  

WITH INTERNAL  

CONTROL ELECTRONICS  

Series 31 / ENERGY – 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 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, aircraft, ground support equipment and lift trucks.  

Our robust design of our bi-stable relays provide 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-  

ages of 12 & 24 V and nominal continuous amperages of 300 Amps.  

Contact voltages up to 250VDC with magentical blowout (>40 VDC).  

Features  

• Sealed

 

housing conforms to IP6K9K  

• Robust

 

design  

Electronic energy storage-control  

• Variety

 

of configuration options  

• 6G

 

shock and 4G vibration resistant  

The relay has only two control connections which make it possible to  

replace a standard monostable relay with a bi-stable relay providing  

the advantage of powerless holding.  

• “Energy”

 

function for automatic shutoff  

in case of loss of power improves safety  

levels and reaction times in critical  

situations.  

The internal capacitor is charged during the switch-on process. When  

the power supply is removed, the capacitor discharges the power into  

the drop out coil, which therefore switches off the relay. The character-  

istics of a standard bi-stable relay requires resupply of energy to drop  

out the coil. The electronics are short-circuit protected and feature  

safety coil selection, reverse polarity protection and coil cancellation.
