Overview
The Pneumercator LC1000-A liquid level alarm console is an intrinsically safe audible and visual alarm system designed for industrial tank monitoring. It monitors liquid level or secondary containment leak conditions using float switches and other dry contact sensors, providing immediate notification of alarm conditions with a bright LED indicator and loud audible horn.
Key Features
- Multi-Channel Configuration: Available with 1, 2, 3, or 4 sensor input channels with corresponding LED indicators and Form C relay outputs
- Intrinsically Safe Design: Low-voltage sensor interface (12 VDC at 15 mA) with up to 5000 feet sensor cable run capability
- Audible and Visual Alarms: 85 dB minimum horn output and super-bright LED indicators for alarm acknowledgment
- Weatherproof Enclosure: NEMA 4X (IP56) fiberglass enclosure standard; optional stainless steel or NEMA 7 explosion-proof enclosures available
- Wide Input Power Range: Universal 95–250 VAC, 50–60 Hz auto-switching power supply
- DIP Switch Configuration: Field-adjustable relay reset behavior and alarm functions
