Do DIN rail mount interface relay modules with a "spare" terminal exist?

Question

I'm currently designing an industrial control panel that I'd like to be as compact as possible, and was looking at interface relays, and was hoping to find a specific feature, but now I'm not sure it exists.

Basically, I'd like a relay module with an extra connection point for the "other" wire to the actuator. ie. the relay will switch the +ve wire, but the module has an extra connection for the 0V wire. This would be bridged to all the other adjacent relay modules with a jumper bar.

The benefits would be:

• Fewer terminals - hopefully cheaper and takes up less space
• Wires from a given actuator terminate right next to each other - tidier and easier to understand and debug.

Another way of describing what I'm looking for would be to combine these two devices: interface relay module & a sensor/actuator terminal block (ground connection to the rail optional):

Does anyone know if such a thing exists?

Answer 1

See Phoenix Contact FBST, it's a bar that goes in the slots under the wire connector you see on the blue relay module.

Finder will have similar. 093.16 for example. See their catalog.

Keep an eye on the total current running in this bar.

Tip: when looking at this kind of industrial products. Find the catalog PDF! It has more seachable info than the websites. Eg: eaton, phoenix, finder. Anyone with this much products.

Answer 2

I've accepted @Jeroen3's answer, but for those looking for the actual product I've selected:

Finder 39.51.0.024.0060

• 39 series, the MasterOUTPUT modules
• relay (not solid-state)
• push-in terminals
• 24V AC/DC coil
• AgNi contacts

• 93.16 as a commoning bar
