Transducer Output:

ELMEASURE transducers are programmable which converts electrical parameters like voltage, current, frequency, power, power factor into DC current (0-20mA/4-20mA) programmable or DC voltage (0-1V). Applications: electrical, chemical, thermal power plants, etc. to monitor processed data either locally or remotely using SCADA by ELMEASURE or 3^rd party.

• Accuracy: Class-1.0FS
• Maximum Overload: 120% (equivalent of 24mA)
• No. of O/Ps: 1 (0-20mA/4-20mA/0-1V DC)

Features & Benefits:

• Programmable primary/secondary voltage or current making wider range of operations
• Programmable transducer O/P either 0-20mA or 4-20mA. Maximum load resistance: 75Ω
• 0-1V DC optional
• A DC or V DC directly proportional to the change of input
• Fully protected against open or short circuit output
