JH5800 POTENTIOMETER INPUT TRANSMITTER
DIN-RAIL MOUNT, FIXED RANGE
|
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.
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). |
| 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: | Under 100 milliseconds. |
| 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. |
