Modbus Display STR571 with OLED

General Description

The Modbus Display STR571 is an OLED panel mount Modbus RTU Master that can display registers and inputs from Senors on the Modbus RTU network. The Modbus Display also has digital inputs and relay outputs providing alarms for the process variables. The display can show one process variable or up to 8 process variables. Combining the one process variable choice with the OLED display makes it a great choice for long distance visualization whilst still only taking up a 1/8 DIN space. Up to four process variables can be shown per page and the texts associated with the parameter. The display can be toggled by either the front panel keyboard switches, a timer or the digital inputs.
