The Tracker 280 series of digital panel meters are designed for use with AC or pulse output sensors. They can be used for measurement and display, or can act as a transmitter using the analog output. A relay output allows use as an alarm trip or batch controller. Applications include: pulse totalisation, pulse rate, frequency measurement, up/down counting, batch control, position measurement with encoders, encoder quadrature measurement or general timing.
These panel meters are fitted with an RS422/ 485 serial communication interface, allowing use as an acquisition device for PC systems. Modbus RTU and ASCII protocols provide compatibility with SCADA software such as DAQFactory.'
