JH4300: DC Voltage or Current Inputs, Input/Output Isolated
Model JH4300 provides a DC output proportional to a DC voltage or current input. A fixed-range device, it is precisely calibrated to your specified range at the factory. (For a rangeable device see JH4380W Fully Rangeable Transmitter.)
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.
A low-drift input amplifier is included for millivolt-level inputs. This feature was formerly an extra-cost option designated by Model Number JH4310. Available options include AC or DC power choices and reverse-action Option RT (decreasing output with increasing input).
Specify Option U
The JH4300 plugs into any standard 8-pin circular ("octal") relay socket. JH Technology offers a socket suitable for DIN-rail or surface mounting (see the Accessories page). Pin connections are:
Pin 1: Power (AC or, if DC power option, DC plus).
Pin 2: No connection.
Pin 3: Power (AC or, if DC power option, DC minus).
Pin 4: No connection.
Pin 5: Input plus.
Pin 6: Input minus.
Pin 7: Output plus.
Pin 8: Output minus.
(Input Impedance: 200kohms or greater.)
(Input Resistance: Varies with input range. Contact factory for details. 62 ohms for 4/20mA input.)
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).
+/-0.1% of span or 10 microvolts, whichever is greater.
Zero and span each are adjustable approx. +/-15% of span.
+/-0.05% of span or better.
Under 100 milliseconds.
Power, 1,500Vac rms (2,100V peak). Input/Output 1,000Vac rms (1,400V peak).
-10 to +60 deg. C (14 to 140 deg. F).
+/-(0.02% of span plus 1.3 microvolts) per deg. C, or better.
AC, 115 or 230Vrms, 50/60Hz, 2.5V-A. DC, 12 or 24V, 2.5W
