EM132 Cost-Effective Multi-Function Transducer

Power Meter & Transducer

SATEC EM132 is a multifunction power meter and transducer, ideal for a wide range of applications such as industrial power monitoring and for interfacing SCADA in utility substations. The EM132 can be fitted with a wide range of communication interfaces and I/O extensions, making it a cost-effective combination of a power meter, smart transducer and PLC controller. It is designed for DIN-rail mounting, equipped with built-in communication ports, digital I/Os and anti-tamper enclosures.
