A torroidal transducer that operates on the hall effect principle to measure DC current and provide a proportional analogue output.
The HT1B has a 35mm diameter aperture, through which the conductor is passed. An auxiliary supply is required. Where current output is specified, a dipswitch allows the user to select either 0…20mA or 4…20mA. Both models may be mounted on DIN rail by means of an optional clip.
