Product Description

Model 909M4 Bidirectional Current Transducer provides an isolated 0 to ±5Vdc output proportional to the DC input current.  The transducers have an input current range from ±150Adc to ±2500Adc and the transducers withstand, without performance degradation or damage, a continuous overload of one-hundred times full-scale.

The 909M4 Series delivers performance accuracy over a temperature range from -40°C to +85°C, operate with a supply voltage from +15Vdc ±2Vdc and are low powered.  The unit’s molded construction, with the internal components encapsulated, creates a durable transducer.

The 909M4 Bidirectional Current Transducer comes standard with a 1.50” (3.81cm) removable yoke, allowing for uninterrupted operation installation, which makes this transducer excellent for existing or retro-fit applications, as well as moveable multi-point monitoring.  The transducers are available with a barrier or connector interface, with the connector option available with mating connector.
