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).
