MFDP Multi-function Display Unit/Transmitter

MFDP Multi-function Display Unit/Transmitter
Applications& Features
Analog inputs: max. 3×(4~20mA/0~10V); over voltage and reverse
 Designed for flush mount, measure and display environment
temperature, humidity and diff. pressure
 316L front panel, PMMA window, flat surface, no dust stay,
good for all detergents, sanitizers and bactericides
 Parallel or alternatively display input channels 1 to 3
 Large high light 3.2” color TFT LCD display
 Multiple inputs and outputs for different applications
 High accuracy sensor, 100% field changeable
 Optional 3 analog 4~20mA/0~10V inputs signals
 Optional 3 analog 0~10V outputs signals
 Optional RS485/Modbus RTU and key functions
 Compatible to any DDC/PLC/SCADA or other data collect
and control systems
 Very high performance/price ratio: replace the single
channel (T/RH/DP) display instruments, provide value
added multi-function combination including local
measurement, displaying and networking
Analog outputs: max. 3×(0~10V); over voltage and reverse
polarity protection; accuracy as low as 0.2%FS; load
resistance >2KΩ; range: same as analog inputs
Keys: set/reset alarm, DP re-zero, calibration, set display
mode, etc.
Communication: 1 USB for parameter checking and setting, 1

Note:
1. When selecting RS485, only the selected channel has the corresponding
function, and the other channels do not have.
2. When the built-in temperature / humidity sensor is selected, the front panel
has a corresponding sampling cap.
3. The total number of output channels should NOT be more than input.
4. MINI model does not have any built-in sensors, and can not have diff.
pressure port on front panel.
