Durakool D41F Interface Relay Assemblies Save DIN Rail Space



Printable Press Release


Willow Technologies Limited ( introduces Durakool’s NEW range of slim interface relays designed to save valuable DIN rail space, occupying only 6.3mm on the rail per relay. The D41F is available with screw terminals or labour saving spring clamp terminals and is designed for PLC interfacing or any application which requires SPCO contacts for switching up to 6A at 230VAC.

John Merrill, Relays Product Manager at Willow commented “The D41F has five different standard operating voltages including the popular 24V AC/DC option, which reduces stock holding as one relay will operate on 12V to 24V DC or AC control inputs.”

“In addition, there is an LED to indicate operation and an ejector lever to enable easy relay replacement, if necessary, when mounted close to other Interface Relays or DIN rail components. The standard colour is a light grey, other colours are available to special, volume, order.” Continued Merrill.

To accompany the range, there are a selection of jumper bars (Terminal Strips) in red, blue and black and a ribbon cable adapter module to make a quick and neat assembly on the DIN rail. Also available is a DIN rail spacer 2mm wide to separate blocks of D41F Interface relays with specific functions.

To compliment the Durakool D41F range of electromechanical interface relays, Willow also offers the SAS Series of solid-state relays which will also fit in the D41F sockets.

“Durakool continue to design and manufacture an extensive range of outstanding quality, innovative and very importantly, highly useful relays, the D41 Interface Relay Assemblies are no exception.” Concluded Merrill.
