Level Display Control Box
Centralized display and control | For tanks, sumps, and open channels
The XY Series Level Display Control Box is a centralized instrument panel designed for remote level monitoring and pump control. It receives standard 4‑20mA signals from level transmitters or other sensors, displays the current level in real time, and provides relay outputs to automatically start or stop pumps, valves, alarms, or other field devices.
Built for control rooms and field installations alike, this control box eliminates the need for personnel to physically visit tanks or sumps to check levels or operate equipment manually.
Description
Key Features
Real‑time level display – Bright digital or dual‑display (digital + bar graph) readout shows current liquid level or volume at a glance.
Flexible input compatibility – Accepts standard 4‑20mA signals from virtually any compatible level transmitter, pressure sensor, or float switch.
Adjustable setpoint control – Upper and lower alarm/control points can be programmed on‑site via front‑panel buttons. No special software or computer required.
Relay outputs for pump/valve control – Built‑in relay contacts (typically 5A or higher) directly control pumps, solenoid valves, fans, or alarm buzzers.
Manual/Auto operation – Switch between fully automatic control and manual override for maintenance or emergency situations.
Optional communication – RS‑485 (Modbus) or 4‑20mA retransmission available for integration with SCADA or building management systems.
Rugged enclosure – Sturdy metal or polycarbonate housing suitable for industrial environments, with optional weatherproof or explosion‑proof versions.
