3TX7, 3RS18 Coupling Relays
3TX7 Coupling Relays, Narrow Design
Relay couplers with plug-in design
■
Benefits
Advantages
• Device variants with hard gold-plated contacts, hence high
contact reliability
• 24 V DC version also available as variant with NO contact
• Integrated reverse polarity protection and EMC arc-
suppression diode
• Clearly visible functional state of the relay coupler by yellow
LED
• Plug-in relay with spring-loaded terminals and 6.2 mm width
• Fast exchange with permanent wiring (plug-in relay)
• The wire inlet and terminals can be reached from the front.
This results in faster wiring time and wiring errors are
prevented.
• Tested complete units short mounting time
• Single relays available as components
• Safe isolation according to EN 50178
• 230 V AC/DC versions available
• Linking of supply voltage and control signals with 16-pole
connecting comb
• Galvanic isolation plate for isolating different voltages for
neighboring units

1) The variants with hard gold-plated contacts feature high contact reliability
(also for low currents) and are therefore especially suitable for steady-
state inputs of programmable logic controllers.
