Description
The Schneider Electric (Viconics) R851V-8 8-stage heater step controller for the precise modulation of multi stage heating systems such as electric duct heaters and boilers in HVAC systems. The outputs are AC/DC isolated and the outputs include an integrated vernier output that allows for smooth load modulation from 0 to 100% capacity. If used with a slave unit, the controller supports up to 16 stages. Designed with a microcomputer base, its accuracy is ensured and system efficiency and longevity are enhanced by adjustable inter stage delays and sequencing options of LIFO/FIFO. It is a suitable industrial heating process solution, with durable and robust temperature control solutions.
