The DT9222 … 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 control panel. Any optional display range can be assigned to the input signal range. Large 5 digit, 20.3 mm character height LED display with adjustable brightness make process value easily visible at a 10 m distance.
The instrument is available with the following output options:
The functional parameters can be set by push-buttons on the front panel of the device, through a simple menu system: input selection, averaging of input signals, scaling, display frequency, limit values, limit operating modes, scaling the analogue output, etc. The settings are protected by a two-level password against unauthorised manipulation.
The instruments has two power supply versions: 24 VDC ±10% (DT9222 …) or 230 V AC/DC ±10% (DT9222 … PS).
The DT9222 … is housed in a moulded polycarbonate case which is dust-tight and houseproof to IP 65 to allow for installation in the field or on the control panel.
