Overview
The ABB 720115-1 STAL split range control card is a specialized analog control module engineered for two-position valve and damper actuators in HVAC and industrial process applications. This control card operates as part of ABB’s STAL series, converting a single analog input signal into dual simultaneous control outputs with independent ranges. The split range card is essential for applications requiring synchronized control of multiple actuators from a single controller input.
