6.2 mm interface relays - maximum functionality in minimum space
In an era of miniaturisation and optimisation of control cabinet space, the 6.2mm-wide interface relays provide an invaluable solution for automation system designers and integrators. These compact components enable signals to be connected efficiently while ensuring full functionality, safety and reliability. Relpol's 6.2 mm wide interface relays - SIR6W, SIR6WB, PIR6W, PIR6WB series and relays of these series dedicated to long control lines - are the answer to these needs.
Application of 6.2 mm relays
The 6.2 mm narrow profile relays are widely used in:
- Industrial automation systems - as intermediary elements between control signals and actuators (e.g. actuators, valves, motors).
- Machine and plant construction - wherever installation space in switchboards and control cabinets is limited.
- HVAC systems - for switching low-voltage signals while galvanically isolating them.
- Control cabinets and low-voltage switchgear - to isolate input signals from output signals.
- In electrical systems - as a standard interface between the control system and the executive system.
Key advantages of narrow-profile relays
-
Minimal width - maximum space savings
With a width of just 6.2 mm, the relays allow a significant reduction in cabinet space, enabling more components to be mounted on a single DIN rail. -
Szybki i łatwy montaż Quick and easy installation
Modules in ready-to-install versions (with spring or screw terminals) enable fast DIN rail mounting -
Interchangeable relays and auxiliary components
In the event of a fault, the relay itself (either the RM699B series electromagnetic relay or the RSR30 solid-state relay) can be quickly replaced without having to remove the entire module. Additional features such as protection diodes, varistors or indicator diodes increase the functionality of these relays. https://www.relpol.pl/en/Products/Miniature-PCB-power-relays -
Safe galvanic separation
Provides protection of the control circuits against interference and surges from the executive circuits. -
High operational reliability
Thanks to their proven technology and robust design, these relays are well suited to industrial environments with demanding requirements.
Interface relays for long lines - eliminating interference on control lines
Interface relays for long control lines are specially designed modules for handling signals that have to travel a considerable distance between the controller and the actuator.
Their design:
- Enables reliable and stable switching of signals even with long cable lengths,
- Contains interference filters to protect the system from false tripping due to induced overvoltages,
- Works well in complex automation systems where remote control is implemented over long distances.
Applications: distributed control systems, installations in large industrial plants, production halls, technical infrastructure of buildings.
