Bi-Polar DC Transducer Sensor
Split-Core Bi-Polar DC Transducer sensor that measures up to 200 Amps of DC current in both flow directions.
Requires analog port selection during U30 system configuration and use of a S-FS-CVIA when using the H22-001 data logger. When using a U12 data logger, this sensor requires a 4-20mA input cable (CABLE-4-20mA) and external power provided by an AC adapter (AC-SENS-1). When configuring this with an RX3000 system, it requires an analog module (RXMOD-A1).
Note: For measurements larger than 120A the device must be powered by a minimum of 15V to maintain expected accuracy.
