Use
The auxiliary relay groups H2 and H3 are used in interlockings and level crossings for auxiliary circuits. The group H2 can be part of the realisation of the supervisory system EF180 applications in level crossings, for example.
Technical design
The installation of the auxiliary group H2 is carried out on a standard frame. The group can be powered by 18V to 36V DC or using multiplier resistors by 60V DC.
The group is fitted with four relays (2 change-over contacts - CO, 2 normally closed contacts - NC, 2 normally open contacts - NO) and two relays (4 CO, 1 NC, 2 NO).
The group H3 can be mounted with a construction set. The necessary power supply is 18V to 36V DC or using multiplier resistors 60V DC. The group is fitted with 2 relays (2 NC, 2 NO).
