JH5160/JH5170 Square/Square Root Transmitters provide DC outputs proportional to the square or square root of the input. The square root function is most commonly used to linearize differential pressure flow signals.

The input and output ranges need not be the same; for example, the input could be 0/10Vdc while the output could be 4/20mA. These are fixed range devices, precisely calibrated to your specified ranges at the factory.

Red-green Quick-Check LEDs give a quick indication of the relative output. Red is brighter at the low end, green at high, while at mid-scale both are approximately equal. Red-only indicates offscale low while green-only indicates offscale high.

Standard transmitters include filtering to smooth measurements and minimize noise pickup. When fast response is needed, Option HS speeds the response time to approximately 1 millisecond. Other response speeds are available on special order.

Input/output isolation is standard. Available options include AC or DC power choices and reverse-action transmitter (decreasing output with increasing input).

ORDERING INFORMATION

Model Number:  Select from the list above according to your input function. Add suffix A (for example, JH5160A) for AC power, D for DC power.
Input Range:  Specify any DC voltage or current range allowed by the "Input Capabilities" spec, below.
Output Range:  Specify any DC voltage or current range allowed by the "Output Capabilities" spec, below.
Power:  Specify 115Vac, 230Vac, 12Vdc or 24Vdc.
Reverse-Acting Transmitter (decreasing output with increasing input):  Change the last digit of the model number to 1 (for example, JH5161A).
Loop-Powered Output:  4/20mA "current sink" output stage for connection to devices whose inputs provide 24Vdc loop excitation. Change the last digit of the model number to 2 (for example, JH5162A).
High Speed Response:  

Approximately 1 msec (See Specifications). Specify Option HS.
Urethane Coating:  Specify Option U.

INSTALLATION AND CONNECTIONS

JH5100 Series transmitters snap onto 35mm DIN rail. Connections are made to the front-panel terminals. The terminal strip unplugs to facilitate calibrating or replacing the transmitter.

Connections to the 8 terminals (top to bottom) are:
    1:  Input plus
    2:  Input minus
    3:  not connected
    4:  not connected
    5:  Output plus
    6:  Output minus
    7:  Power (AC or, if DC power option, DC plus).
    8:  Power (AC or, if DC power option, DC minus).
