Model: MS5506
Plug-In Strain Gauge Transmitter with Isolated Single Output

DESCRIPTION

MS550051

The MS5506 is a plug-in strain gauge transmitter thatsupplies excitation voltage to strain-gauge type pressure
sensors, load cells, and the like and converts their output
signals into standard process signals. It provides an isolated
single output.

ORDERING INFORMATION
To place an order, please use the ordering code format
as shown above. Also specify a bridge resistance.
(e.g.) MS5506-A-E31A (350Ω)
Other Ordering Examples:
For an excitation voltage code of “0”: MS5506-A-011(700Ω / Excitation voltage: 4V)
For an input code of “0”: MS5506-D-E204 (120Ω / Input: 0to 20mV)
For an output code of “Z”: MS5506-A-E32Z (350Ω /Output: 8 to 20mA)
For an option code of “X”: MS5506-D-E215/X (Responsefrequency: 50Hz)
Note: If you wish to include multiple options in your order,
specify the option codes in series (e.g. /KX).
