Process indicator DT4222 series

with LED display5-digitpanel-mount

The DT4222 … 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 height LED display make process value easily visible at a distance. The instrument is available with the following output options: • 2 normally open relay contacts (SPST) for limit switching or for simple control tasks • 0-20 mA / 4-20 mA galvanic isolated scalable current output * • RS232 / RS485 galvanic isolated communication output with MODBUS RTU slave protocol * • transmitter supply galvanic isolated 15 VDC 20 mA* • 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: 18-35 V AC/DC (DT4222 …) or 180-250 V AC/DC (DT4222 … PS). The DT4222 … is housed in a DIN standard 138 × 68 mm ABS case with IP 65 protection from the front and IP 30 protection from the back side, for installation on the control panel.
