Siemens offers a wide range of plug-in relays to meet your indus-

trial needs. Basic style relays are the most economical and are

equipped with a mechanical flag indicator only . Premium style

relays are full featured with LED and mechanical flag indication,

push to test button and typically a latching hold down door which

provides a method of activating the contacts without applying

power to the coil. This feature is very handy during comissioning

and troubleshooting. Premium Bifurcated style relays are ideal

for low minimum holding current requirements on the contacts.

Typical minimum holding current for bifurcated contacts is 3mA

instead of 100mA.

Relays are divided up by the following functions for selection:

• Base style

• Contact Arrangement

• Contact Rating

• Coil Voltage

• Optional Features (Basic, Premium and Premium Bifurcated)

Function Relays, Interfaces and Converters • Revised • 03/21/2011 3TX71 plug-in relays SIRIUS RELAYS Multifunction Timer Modes Function Name Description A On Delay (Power On) When input voltage U is applied, timing delay t begins. Relay contacts R change state after the time delay is complete. Contacts R return to their shelf state when input voltage U is removed. Trigger switch is not used in this function. B Repeat Cycle (Starting Off) When input voltage U is applied, time delay t begins.
