Supported Applications
The Omega LVCN-140 is a single-input high or low relay controller designed for general-purpose level control. It provides alarm functions and controls pumps, valves, and actuators based on input from one level sensor.
- Pump and valve control
- High or low sensor alarm indication
Operating Conditions & Performance
The LVCN-140 operates with a selectable power supply of 120 or 240 Vac, 50 to 60 Hz, consuming a maximum of 5 watts. The electronics are rated for an ambient temperature range up to 70°C (158°F). Sensor excitation is provided at nominal 13.5 Vdc with a maximum current draw of 27 mA.
- Maximum Relay Switching Voltage: 250 Vac, 10 A, ½ HP
- Sensor Trigger Point: Dry <12 mA, Wet >12 mA
- Contact Delay (Time Delay): Adjustable from 0.15 to 60 sec.
Mounting and Enclosure
The unit features a flame-retardant PP enclosure designed for EN 50 022 standard 35 mm DIN rail or panel mount applications. The overall dimensions are 6.9 H x 9.9 W x 9.1 cm D (2.7 x 3.9 x 3.6").
Configuration Options
- Sensor Input: Accepts one level switch sensor.
- Relay Output: Isolated single pole double throw (SPDT) relay, Form C.
- Switching Mode: Selectable Normally Open (NO) or Normally Closed (NC).
- Status Indication: LED display for sensor power and relay status.
Certifications
The series includes a 1 YEAR WARRANTY. CE approval is available by adding the suffix “-CE” to the model number at an additional cost, meeting EN 61326 EMC and EN 61010-1 Safety standards.
Key Product Differences
The LVCN series includes three configurations: the LVCN-140 (single sensor input, single relay output), the LVCN-130 (one or two level switches with a latching relay), and the LVCN-120 (up to three sensors with both standard and latching relays). The LVCN-140 is distinguished by its single 10A SPDT relay output configured for one sensor input.
