3TX7, 3RS18 Coupling Relays
3TX7 Coupling Relays, Narrow Design
Relay couplers
■
Application
AC and DC operation
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.
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.
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.
