NEMA

The Siemens m50 series controllers are an innovative, fully actuated controller unit with an extensive compliment of operational, programming, and diagnostic capabilities. The m50 series exceeds many industry standards and specifications with advanced functionality beyond the normal NEMA standards. The m50 features new capabilities and enhancements in hardware design and communications. The series consists of the m51 TS2 Type 1, m52 TS2 Type 1,2 and the m53 TS2 Type 2 models.

Hardware Features

The M50 features a removable, hand-held LCD alphanumeric backlit display unit.

Handheld Display

The M50 features a removable, hand-held LCD alphanumeric backlit display unit, with 8-line, 40 character per line display capability. The display unit connects to the controller via a dedicated C60 port.

 

The controller is convection cooled with vent slots in the back and openings along the bottom. Adjustable rubber feet along the front allow users to change the angle of the display and create more or less space around the controller. Grounding metal feet in the rear stabilize the controller.
