Model A-900 & A-901 1/4 DIN Control Enclosure

Brand: Dwyer Instruments, LLC

Models A-900 and A-901 are the perfect instrument housing for indoor and outdoor applications.

Protects controls from dirt, dust, oil and water. Unit is rated weatherproof type NEMA 4X and has a fully gasketed cover. Standard features include a lockable latch to prevent tampering and flush mounting hardware.

The Model A-900 comes standard with a 1/4 DIN cut out in the front cover. Controller will mount with front face exposed for easy access to the programming buttons. Love and Mercoid controllers feature weatherproof NEMA 4X rated front panels and gaskets enabling the control to be weatherproof protected when installed in the A-900 even though the front face is exposed. 

Wiring an installed control is easy due to the hinged cover and spacious clearance for the control to swing out with front cover. The lockable latch prevents unauthorized removal of the control from the enclosure.

The Model A-901 comes standard with a clear plastic front window and mounting hardware to install the control inside the box. Controller mounts just behind the window assuring easy viewing.

Mounting the control inside the enclosure protects the control face from corrosive atmospheres or from being covered in oil, dirt and dust. The lockable latch prevents unauthorized removal of the control and removes access to the control programming buttons. 

The mounting hardware is attached to the rear of the enclosure and includes a bracket with a 1/4 DIN cutout and standoffs long enough for Love and Mercoid controls to fit. Control programming buttons are easily accessible by just opening the front cover.
