Description
The Schneider Electric (Barber Colman) M800A-S2 is a high-performance Forta series globe valve actuator engineered for precise control in commercial and industrial HVAC hydronic systems. Designed to operate on 24V power, it supports both floating and proportional control modes, making it a versatile solution for a wide range of building automation and valve control applications.
Control Signal Compatibility
- Floating control mode for simple open/close positioning
- Proportional control via 0 to 10Vdc input signal
- Proportional control via 2 to 10Vdc input signal
- Proportional control via 4 to 20mA input (requires 500 Ohm resistor, included)
- 2 to 10Vdc feedback signal for position confirmation and system integration
Actuator Performance
- 180 Lbf (pound-force) output for reliable valve actuation under demanding conditions
- Compatible with Forta series globe valves for matched system performance
- U-bolt mounting design for secure, stable installation
Auxiliary Switching
- 2 SPDT (Single Pole Double Throw) auxiliary switches for end-of-travel indication or ancillary equipment control
- Enables integration with building automation systems, interlocks, and alarm circuits
