Industrial Durability: Rated for up to 25A resistive loads

The RIBAN24C is an open-board track mount relay

The Type II thermistor used in this model has a distinct resistance-to-temperature curve (steeper at lower temperatures) compared to Type III

Johnson Controls V-9502-6801 Positioner Spring or the control board flashingThe Johnson Controls V 9502 6801 Positioner Spring is a critical component for fine tuning the pneumatic actuator response in legacy HVAC control systems. Specifically designed for use with V 3000 Actuated Valves, this spring establishes a fixed operating span, ensuring precise valve positioning and stable flow control. Unlike other series where the span is field selectable via lever arm positioning, the V 3000 series relies on specific spring rates
