The DT4226 … Process Indicator enable linear process variables (0-20 mA / 4-20 mA / 0-10 V / 2-10 V / 0-5 V) to be displayed in engineering units on the place of installation. Any optional display range can be assigned to the input signal range.
Large 5 digit, 101 mm height LED display with adjustable brightness make process value easily visible at a 50 m distance.
The functional parameters can be set by membrane push-buttons on the front panel of the device, through a simple menu system: input selection, averaging of input signals, scaling, display refresh rate, etc. The settings are protected by a two-level password against unauthorised manipulation.
The instruments has two power supply versions: 24 VDC ±10% (DT4226 …) or 230 V AC/DC ±10% (DT4226 … PS)
The DT4226 … is housed in a metal case with IP40 protection for installation on a flat surface (e.g. wall).
