04 / DIMENSIONS

Panel-mount dimensions.

Common single-channel enclosure dimensions for the MGR-1 A48 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 A4840

Load above.
Control below.

Upper terminals 1 and 2 switch the AC load. Lower terminals 3 and 4 accept 70–280 V AC, without polarity. Keep control and load supplies distinct.

PRINCIPLE / MGR-1 A4840

A command.
A switched load.

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