£90.40
The ABB MREL-01 is a compact relay output extension module designed to expand the control and signalling capability of compatible ABB machinery drives. It provides additional relay outputs for applications where extra status, alarm, interlock or process control signals are required.
Designed for use with ABB ACS310, ACS350 and ACS355 drives, the MREL-01 offers a practical way to add relay-based control functions without requiring a separate external relay interface. It is ideal for panel builders, maintenance engineers and OEMs looking to increase drive I/O flexibility in compact control systems.
The module provides three additional relay outputs and is installed as a drive option module. Its compact format makes it suitable for integration into industrial control panels and machine cabinets where reliable drive signalling is required.
The ABB MREL-01 increases the available relay outputs on compatible ABB drives, allowing additional functions such as run indication, fault signalling, warning outputs, process interlocks and external control logic. This makes it a useful accessory for applications where the standard drive I/O is not sufficient.
By providing relay-based outputs directly from the drive system, the module helps simplify panel wiring and reduce the need for additional interface components. This supports cleaner panel layouts and more flexible machine control designs.
