General

• All versions with screw or spring-type terminals (push-in technology)
• Top wiring with spring-type terminals (push-in) for fast and secure wiring.
• Low space requirements in the control cabinet thanks to a consistent width of 6.2 mm
• Reduced inventory due to low variance
• Functional state of the coupling relay clearly indicated by green LED
• Integrated reverse polarity protection and EMC arc-suppression diode
• Uniform accessories throughout the entire 3RQ3 series
• Integrated jumper option using connecting comb for all terminals
• Galvanic isolation plate for isolating different voltages for neighboring units
• Clip-on labels available as plotter matte paper for individual printing

Coupling relays with relay output

• Permanently soldered relays for increased contact reliability
• Device variants with hard gold-plated contacts providing high contact reliability at low currents

Coupling relays with plug-in relays

• Fast replacement of the relays with existing wiring
• Tested complete units > lower assembly time
• Individual relays available as spare parts
• Device variants with hard gold-plated contacts providing high contact reliability at low currents

Coupling relays with semiconductor output

• Long service life as there is no mechanical wear
• High switching frequency thanks to short make and break times
• Insensitive to vibrations
• No contact bounce
• Maximum contact reliability
• Noise-free switching
• Low control power required
• Switching of DC and capacitive loads
