Product Overview
HXWP-LED Manual Operator / Light‑Bar Display Manual Operator
The HXWP-LED series manual operator/controller and light‑bar display manual operator can be connected downstream of various controllers as a backup instrument. In the event of controller failure, this controller enables manual operation and can also replace the servo amplifier to directly drive valves.
The HXWP-LED series manual operator/controller combines digital and analog display functions, enabling both digital display and control (with high-brightness LED digits) and relative analog display (light‑bar indication) for measurement signals such as temperature, pressure, liquid level, and speed, thereby presenting measured values in a clearer, more intuitive manner. A dual‑light‑bar display mode is also available.
Key Features
1. It can be equipped with one analog control output, one digital control output—relay‑based forward and reverse control—and one analog transmitter output, making it suitable for a wide range of measurement and control applications.
2. It supports seamless automatic/manual switching without disturbance. When switching from manual to automatic mode, it employs an incremental calculation method with a switching limit‑clamping function to ensure smooth transition between the two modes.
3. The measurement signal and the feedback signal can be displayed on the same screen.
★Model example: HX-WP-ND835-81-15/15-HL-P-W
The communication interface is RS485; the output is relay‑based, with forward/reverse switching. The PV input range is 4–20 mA, and the SV input range is also 4–20 mA. The first alarm is an upper‑limit alarm, and the second alarm is a lower‑limit alarm. A 24 V DC power supply is provided for both output and input.
