The RIA15-GRA2 indicator

For indication of 4...20 mA or HART® signals for a sensor or control device in place or on the control panel

The process indicator is available in variants for 4...20 mA or for the HART® protocol. In the HART® version, up to 4 variable values from a single sensor are displayed alternately. To do this, the indicator is configured as Primary or Secondary Master HART® and actively polls the sensor to obtain values. Due to the compactness of the field and panel versions, the device is easy to install in any field of application. Slight voltage drop < 1 В (< 1,9 В в случае HART®) является преимуществом особенно во взрывоопасных зонах, где обычно возможно подключение только пониженного напряжения.
