Functional Devices RIBTE24B 20 Amp SPDT Relay 24V Low Input Optoisolated

The Functional Devices RIBTE24B is a low input, optoisolated relay designed for commercial and industrial HVAC control applications. This versatile relay provides reliable switching of 20-amp loads with complete electrical isolation between control and power circuits.

Key Features:

• 20 amp SPDT (single pole double throw) relay contact configuration for flexible switching applications
• 24 Vac/dc power input with wide-range 5-25 Vac/dc control input voltage
• Optoisolation provides complete electrical separation between high and low voltage circuits for enhanced safety and noise immunity
• Hi/Lo voltage separation protects sensitive control circuits from power circuit interference
• NEMA 1 rated enclosure suitable for indoor general purpose applications
• DIN rail or surface mounting options for versatile installation
• LED status indicator shows relay coil energization at a glance

The RIBTE24B relay is ideal for switching heating, cooling, fan, and other HVAC loads in building automation systems, energy management controls, and other applications requiring isolation between control and load circuits. The low input voltage sensitivity allows operation from thermostats, PLCs, time clocks, and other low-power control devices.
