Easy Panel Mounting for the RD300

Mounting the RD300 display is a straightforward process designed for efficiency and reliability. Begin by preparing a standard 1/8 DIN panel cutout measuring 3.622" x 1.772" (92 mm x 45 mm) while ensuring at least 6.0" (152 mm) of clearance behind the panel for wiring. The panel thickness should be between 0.04" and 0.25" (1.0 mm to 6.4 mm), with a minimum thickness of 0.06" (1.5 mm) for steel or 0.16" (4.1 mm) for plastic panels to maintain the Type 4X rating. After removing the two mounting brackets, insert the meter into the cutout. Finally, secure the mounting brackets, ensuring even tightness to avoid damage to the panel while achieving a proper seal.

Flexible Operation and Process Control with Customizable Display

The RD300 is a flexible, dual-line display that supports current (0-20 mA, 4-20 mA) and voltage inputs (0-5 V, 1-5 V, 0-10 V, ±10 V), presenting these signals in engineering units across a broad range from -99999 to 999999. Users can configure the upper line to show process variables, while the lower line can display engineering units, custom legends, totals, or set points. With programmable function keys (F1, F2, F3), users can adapt the display to meet unique control requirements, while an additional digital input (F4) offers responsive control through contact closure or active low signals. The RD300 also tracks and displays maximum and minimum readings, providing insight into peak process performance with options for continuous or momentary display. This comprehensive adaptability makes the RD300 a valuable choice for applications requiring precise monitoring and control.
