Frequency Monitor

29SG

The 29SG Frequency Monitor provides essential frequency monitoring capabilities for industrial applications. It accommodates a broad input voltage range of 80-550 VAC and offers precise frequency detection from 40Hz to 70Hz, with an extended range up to 560Hz via a 400Hz jumper. Configurable high and low frequency set points, along with adjustable trip delays from 0 to 20.0 seconds, allow for tailored system protection. Output is managed by SPDT x 2 contacts, rated at 10A @ 240VAC, ensuring robust control. The unit features both automatic and manual reset options, enhancing operational flexibility and system uptime. Its Lexan Polycarbonate enclosure and 35mm DIN rail mounting facilitate straightforward integration into existing control panels. This monitor is designed for consistent performance across an operating temperature range of -20°F to +130°F, maintaining reliability in diverse industrial settings.
