04 / DIMENSIONS

Panel-mount dimensions.

Common single-channel enclosure dimensions for the MGR-1 DD220D series. All dimensions are in millimetres.

MGR single-phase panel-mount solid state relay dimensional drawing in millimetres — Overall size: 57.4 × 44.8 × 28 mm

CONNECTION / MGR-1 DD220D40

Load above.
Control below.

Upper output terminals are 2 (+) and 1 (−). Connect supply + through the fuse and DC load to 2 (+), then 1 (−) to supply −. Lower terminals are 3 (+) and 4 (−), for 3–32 V DC control.

PRINCIPLE / MGR-1 DD220D40

A command.
A switched load.

The DC control input enables the DC output stage. This is on/off switching, not proportional voltage regulation. The animation is a functional block diagram, not an internal component schematic.
