3TX70 relay couplers are available in two basic

versions. The 3TX7004/05 is only 6.2 mm wide:

taking up a lot less space in the electrical cabi-

net. Then there is the 3TX7002/03 series:

These devices are suitable for mounting in

small electrical cabinets with a low depth and

short distances between the mounting rails.

Both series are available with an extensive

range of input and output couplers.

Your advantages: 3TX7002/03 and 3TX7004/05

• Operating range from 0.7 to 1.25 V

at 24 V DC

up to 60 °C

• Protective circuit is integrated in the input

• Connection comb and cable to connect voltages at the

same potential

• Manual-0-automatic switch for easier commissioning

Your advantages: 3TX7014 and 3TX7015

• Plug-in relays that can be quickly replaced with

preassembled wiring

• Conductors are introduced and clamped from the front

– therefore shorter wiring times

• Tested, complete devices reduce installation times

• Individual relays are available as spare parts

• Relay version with hard-gold-plated contacts –

therefore achieving a high contact reliability

Applications:

• Electrical isolation

• Voltage conversion – e.g. from 24 V DC to 230 V AC

• Signal amplification

• Contact multiplication

• General relay controls

• Overvoltage and EMC protection of controls

Engineering information:

When selecting the interface for rated control supply volt-

ages of 110 V AC and 230 V AC, the maximum permissible

cable length must be carefully observed. The special

3TX700-…05 relay can be used for longer cables.
