These metering pumps now offer four configurable outputs
Qdos chemical metering pumps (photo) now feature four configurable outputs to help users cut down on the need for additional PLCs and provide extra flexibility when communicating with SCADA or other external monitoring systems. The company has expanded its accurate and versatile Qdos Universal + Relay series to provide four configurable outputs, as well as the 4–20 mA. As a result, users can access increased options for connectivity, enabling improved communication regarding pump performance and function status. All Qdos Universal + Relay pumps produced after March 2020 feature four changeover relay outputs, with either 110 V a.c. 4-A, or 24 V d.c. 4-A contact rating. — Watson-Marlow Fluid Technology Group, Falmouth, U.K.
