SD16A – Digital Indicator

The SD16A was designed for the control of temperature, humidity and other physical values of general industrial equipment.

Digital indicator of large display and multi-input (thermocouple, RTD, DC voltage) with 48 x 96 mm size, character height 20 mm.
DC current signal can be used as an external shunt resistor.
Can be used for indication and remote indication of temperature/humidity pressure.

The SD16A supports Modbus/Shimaden communication protocols.
