    DATA SHEET

The Model JH5040 DIN-Rail Transmitter provides an isolated DC voltage or current output proportional to a 4/20mAdc input. Designed to isolate and convert signals from 2-wire (loop-powered) transmitters, it includes a regulated 24Vdc input loop supply. The input also may be configured for standard 4/20mA inputs, bypassing the 24V supply.

Other input ranges are possible. For example, the loop excitation supply might be used to power a "3-wire" style transmitter having 0/5V or 0/10Vdc output. Contact us with your requirements.

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 JH5040A for AC power, JH5040D for DC power..
Input Range:  4/20mAdc. Others available - contact factory.
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 model number to JH5041(A or D).
Loop-Powered Output:  4/20mA "current sink" output stage for connection to devices whose inputs provide 24Vdc loop excitation. Change model number to JH5042(A or D).
Urethane Coating:  Specify Option U

INSTALLATION AND CONNECTIONS

Model JH5040 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.
2
:  Input minus.
3
:  +24Vdc loop excitation.
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).
