• Operating Temperature: -20°C to +60°C
• Humidity: Up to 95% (non-condensing)

Electrical & Communication

• Voltage Input: 115/240 Vac, 125 Vdc (high) and 24 Vdc (low)
• Speed Output: 4–20 mA
• Communication: Modbus relays

Durability

Conformal coating protects against sulfur contamination and harmful gases like H2S and SO2.

Installation & Maintenance

Panel mount design with 2-out-of-3 voted architecture for continuous operation and redundancy.
