Supported Applications
The Omega LVCN Series comprises general-purpose level controllers designed for pump and valve control. The series includes three configurations: the LVCN-140, which accepts one level sensor input; the LVCN-130, configured for one or two level sensors with a latching relay output; and the LVCN-120, a three-input system capable of automatic fill or empty operations combined with high or low alarm functions. The LVCN-120 can also function as a two-input controller to perform dual alarms (2-high/2-low or 1-high/1-low). These controllers are packaged for use with level switch sensors and fittings.
Operating Conditions & Performance
The series operates on selectable power supplies of 120 / 240 VAC, 50 - 60 Hz, with a maximum consumption of 5 Watts. The electronics are rated for an ambient temperature range of F: -40° to 158°, C: -40° to 70°. Sensor inputs receive a nominal supply voltage of 13.5 VDC @ 27 mA (maximum), with trigger points defined as Dry <12 mA and wet >12 mA.
Relay outputs are isolated single pole double throw (SPDT) relays, Form C, rated for a maximum switched load of 250 VAC, 10 A, or ½ HP. The series features an adjustable contact delay ranging from 0 to 60 seconds (specifically noted as 0.15 to 60 sec in the LVCN-120 specification) to eliminate relay chatter. LED indicators provide status for sensor input, power, and relay output.
Configuration Options
The series offers configurable mounting options via a PP (U.L. 94 VO), flame retardant enclosure designed for EN 50 022 standard 35 mm DIN rail or panel mount installation. The overall dimensions are listed as Width: 3.9" (98mm) / Height: 2.7" (68mm) / Depth: 3.6" (92mm), with a side view depth of 1.8" (44mm).
Key configurable capabilities across the series include:
- Sensor Inputs: One input for LVCN-140; one or two inputs for LVCN-130; one, two, or three inputs for LVCN-120.
- Relay Outputs: Single SPDT relay (LVCN-140); single SPDT latching relay (LVCN-130); combination of one SPDT and one SPDT latching relay (LVCN-120).
- Contact Configuration: Selectable Normally Open (NO) or Normally Closed (NC) states.
- Latch Functionality: Select On/Off latch available on LVCN-120 and LVCN-130 series only.
The controllers support fail-safe operation upon power failure. For CE compliance, the suffix "-CE" is added to the model number for additional cost. Compatible level track mounting systems include sensors LVU-150, LVC-100, and LVV-110 (sold separately).
Key Product Differences
The series distinguishes itself through three specific faceplate configurations:
- LVCN-140 Series: Features 1 sensor input and 1 relay output.
- LVCN-130 Series: Features 2 sensor inputs and 1 latching relay output.
- LVCN-120 Series: Features 3 sensor inputs and 2 relay outputs (one latched, one single input).
The LVCN-120 is the only model in the series offering a three-sensor configuration with dual relay outputs. All models share identical enclosure materials and mounting standards but differ strictly by input count and relay logic capabilities.
