MANUAL

The Model JH5800 Potentiometer Input Transmitter provides an isolated DC output proportional to the position of a potentiometer or slidewire wiper. The input range may be 0-100% or any 10% or wider portion of the wiper's travel. Calibration is unaffected by the potentiometer's end-to-end resistance.

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 JH5800A for AC power, JH5800D for DC power.
Input Range:  Specify 0/100%, or other range as required. (See Specifications for input capabilities.)
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, JH5801A).
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, JH5802A).
High Speed Response:  

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

Model JH5800 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:  Counterclockwise (0% travel).
    2:  Wiper.
    3:  Clockwise (100% travel).
    4:  No connection.
    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).

DETAILED SPECIFICATIONS

Input Potentiometer:  May be any resistance between 100 ohms and 100Kohms. Calibration is not affected by the potentiometer's resistance.
Input Capabilities:  0 to 100% travel, or any 10% or wider portion of the travel (for example, 45 to 55% travel).
Voltage Output Capabilities:  1 volt minimum output span, -10 to +15V absolute limit. Offset ranges are allowed. Maximum output load, 10mA (1Kohm at 10V output).
Current Output Capabilities:  1mA minimum output span, 0 to +25mA absolute limit. Positive offsets are allowed, negative outputs are not. Output drive capability, 24V (1,200 ohms max. at 20mA output).
Accuracy (factory calibration):  +/-0.1% of span.
Adjustability:  Zero and span each are adjustable approx. +/-15% of span. When ordered for 0-100% travel, the adjustments are set up so as to allow calibration to any 75% or wider portion of the travel (for example, 0-75% or 25-100%).
Linearity:  +/-0.05% of span or better.
Response Time:  

Standard: Under 100 milliseconds. Option HS: Approximately 95% complete in 1 msec. Frequency response 3dB down at approx. 600Hz.
Isolation:  3-way (Power/Input/Output) 1,500Vac rms (2,100V peak).
Guaranteed Operating Temperature:  -10 to +60 deg. C (14 to 140 deg. F).
Temperature Stability:  +/-0.02% of span per deg. C, or better.
Power Requirements:  AC, 115 or 230Vrms, 50/60Hz, 2.5V-A. DC, 12 or 24V, 2.5W.
