AFP Analog to Floating Point

The AFP allows an analog signal to control a floating point actuator. AFP converts an analog signal into two relay contact outputs (one increase/one decrease). The AFP's isolated floating point output can be controlled by any one of eight analog input signal ranges (using offset jumper).

On a loss of power, the AFP's output relays will be open, and no signal will be generated. The actuator will remain at the last commanded position unless it is "spring return".

An LED indicates power to the AFP. The output rate of change (nine ranges, in four versions) is DIP switch selectable. In Version 4, the AFP relays stay on at minimum and maximum voltage. In Version 5, The AFP relays stays on with 5% of maximum or minimum input voltage. No overshoot on maximun or minimum input voltage. Custom rates of change are available upon re-quest. Call us.
