3TX7, 3RS18 Coupling Relays
3TX7 Coupling Relays, Narrow Design
■ Application
AC and DC operation
DIN VDE 0110 Part 1, DIN VDE 0435, DIN VDE 0660 and
EN 50005
In the coupling links in double-decker format, the connections
are arranged on two levels; the units are extremely compact.
Connection method: Screw terminals or spring-loaded
terminals. For test purposes, versions are available with manual
0 automatic switches.
Relay couplers
The input and output coupling links differ with regard to the
positioning of the terminals and the LEDs. For equipment
identification purposes, each coupling link has a blank legend
plate.
In accordance with the technical specifications of electronic
systems, the coupling elements have a lower power
consumption.

Note:
For coil voltages which are not listed, see SITOP power DC Power Supplies, e.g. 6EP1 331-2BA10 and 6EP1 731-2BA00, in "Power Supplies".
1) Hard gold-plated contacts.
2) The same potential must be applied to the output contacts of the
2 NO/2 CO relays.
3) Observe max. permissible conductor length, see Technical
Specifications.
