DPT Digital Programmable Transducer

Product at a glance

Our family of DIN-rail programmable transducers (DPT) measure a wide range of electrical parameters and generate equivalent analogue output signals suitable for interfacing with instrumentation and control systems. DPTs are available with up to four analogue outputs, up to two digital outputs and Modbus communication functionality. All the outputs are galvanically isolated and can be programmed with easy-to-use ConfigView software. Any of the measured parameters can be assigned to the analogue outputs and can be read out via the optional Modbus connection. ConfigView can also be used to configure the connection to the measured circuit for single-phase, three-phase three-wire, three-phase four-wire, balanced or unbalanced load. DPTs comply with IEC 60688 and are available in accuracy classes 0.5 and 0.2. DPT support wide range of voltage, current and auxiliary supply.
