Series SC and SU Staging Controllers (Type A) are multipurpose units designed for pilot-duty sequencing of multiple process control stages of either heating or cooling. Type A controllers require 4 to 20 mA DC signals from a temperature controller or a slide-wire potentiometer. All input signals to the units are optically isolated. Other features include solid-state output stages; up-down or circular operating modes; logic status lights; choice of current, voltage or resistance input; 10-stage capacity; and fused output stages.
