Features & Benefits of Moniteur’s Sentinel II VPT
The most popular switch for general purpose applications is rated 15A at 120 VAC and 2.5V at 24 VDC. Our standard mechanical switches are specified with higher operating forces and offer better resistance to freeze up. Gold Plated SPDT switches rated at 1A at 24 VDC are a low-cost alternative for intrinsically safe applications. DPDT Mechanical Switches rated at 10A / 125 VAC and 7A / 24VDC are also available. Specifications
A wide variety of industry standard sensors is available to interface with control systems found in today’s modern process plants. Specifications
These hermetically sealed switches set the standard for reliability. Tungsten TTL switches are used for high current AC and DC applications with a rating of 3A at 120 VAC and 2A at 24 VDC (100 Watts Max). Choose Rhodium TTL for low voltage / low current DC and Intrinsically Safe applications. Optional LEDs are also available on the Krystal TTL with Rhodium contacts. NOTE: Switches with Tungsten contacts are not recommended for DC signals lower than 50mA. Specifications
Current or Resistive Output are available for 0-100% / 4-20mA feedback. Our electronics have been designed for severe applications and have been proven to outperform our competition in the toughest of environments. Specifications
