Air Supply Failure
Single Acting Relay
On supply failure the actuator output drops. Some overshoot
may occur when air pressure returns after a period without air
supply pressure. Always set control set point to 0%, and put
the process control system in manual, for smooth recovery
from air supply failure.
Loss of Input Signal
Output drops to low pressure.
Output Pressure
0-120 psi (8.27 bar) max
