Double arma­ture relay with two in­de­pend­ent 4-pole for­cibly guided con­tact sets

Double armature relay with two independent 4-pole forcibly guided contact sets

The new relay series SID4 is a double armature relay which is equipped with two independent forcibly guided contact sets in accordance with IEC 61810-3 type A. This allows, among other things, the implementation of 2-channel control architectures for functional safety, e.g. SIL3 (IEC 61061) or Pl "e" (ISO 13849).

The area saving compared to solutions with two comparable conventional relays is around 22%. Due to the internal wiring of the contact sets and only one solenoid coil, the number of holes on the PCB is reduced from 20 to 10. The plastic content of the relay could be reduced by 39% compared to 2 pieces of SIF312. Two assembly areas for components up to a height of approx. 3 mm were created under the relay housing. In comparison, the coil power could be reduced by about 40%. The nominal power is 820 mW. Coil voltages from 5 VDC to 110 VDC are available.

In addition to solder mounting, ELOPINS (press-fit technology) is available as a solderless mounting technique. The press-fit contacts ensure a gas-tight connection to the PCB. This goes hand in hand with high connection quality and saves resources, as there is no need for a soldering process.
Approvals from UL and TÜV are available. Samples can be provided at short notice.
