Product description
The DT4260 … AC Current Meter enable 0-1 AAC / 0-5 AAC current ranges to be displayed on the control panel. Large 5 digit, 14.2 mm character height LED display make process value easily visible at a distance.
The displayed value is proportional to the True RMS value of the input current. The input current should be connected to the instrument’s shunt input through a current transformer.
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 *.
(* either analogue or communication option can be implemented at the same time)
Easy on-site configuration through the front panel membrane keypad is a major advantage of the microcontroller-based technology.
The configuration parameters: input range, current transformer ratio, signal filtering, output scaling, display refresh
rate, limit modes, limit values, etc. are stored in EEPROM. The settings are protected by a two-level password against unauthorised manipulation.
The instruments has two power supply versions: 24 VDC ±10% (DT4260 …) or 230 V AC/DC ±10% (DT4260 … PS).
The DT4260 … is housed in a DIN standard 96 × 48 mm ABS case with IP 65 protection from the front and IP 30 protection from the back side, for installation on the control panel.
