This range of isolated transmitters or signal conditioners take their power on separate terminals to their output signals. This allows them to output 0-10V, 0-20mA and 4-20mA where applicable. It also enables a high impedance load to be driven from the mA output signal.
The Acromag devices come with 5 years warranty and excellent stability.
The ISC range of low cost isolating signal conditioning devices may be scaled to suit a wide range of input values, but signal type must be chosen when ordering eg thermocouple input.
