MANUAL

The Model JH5500 Strain Gauge Transmitter supplies excitation to a strain gauge or other resistance bridge, amplifies the bridge voltage and provides a proportional, isolated DC voltage or current output. A low-drift input amplifier maintains accurate readings under varying ambient conditions.

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.

Available options include AC and DC power choices and reverse-acting transmitter (decreasing output with increasing input).

ORDERING INFORMATION

Model Number:  Specify Model JH5500A for AC power, JH5500D for DC power.
Input Range:  Specify range required in millvolts (mV), volts (V) or millivolts per volt (mV/V). For example, with 10V bridge excitation a range of 0/20mV is the same as 0/2 mV/V. See Specifications below for input capabilities. Offset input ranges are allowed.
Bridge Excitation:  Standard setting is 10Vdc. User-adjustable from 4 to 12Vdc. If you wish a factory setting other than 10V, please specify on your order.
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 last digit of the model number to 1 (for example, JH5501A).
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, JH5502A).
High Speed Response:  

Approximately 1 msec (See Specifications). Specify Option HS.

Urethane Coating:  Specify Option U.

Model JH5500 snaps 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 (bridge output).
    2: 
Input minus (bridge output).
    3:
  Bridge excitation plus.
    4: 
Bridge excitation minus.
    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).
