OLED Panel Meter STR551

General Description

The OLED Panel Meter STR551 is a newly designed display meter that replaced old LCD and LED technology. The OLED Panel Meter can accept signals from 4-20mA, 0-10V, Thermocouples, RTD's and provide a 4-20mA retransmission. The STR551 has a Modbus RTU optional output and up to 2 relays and 2 digital inputs.
The STR551 is a 1/8 din 48 x 96 mm panel mount instrument which can be mounted horizontally or vertically. It can display process variables, bar graphs, alphanumeric characters and with the data logger feature show the stored data in a trend view.
The STR551 Panel Meter has two analog retransmission outputs 0-10V and a 4-20mA. It has two relays that can be used for high, low, threshold, band and these alarms can be instantaneous or delayed, The relays can also be used as a sensor break alarm.
Other features built in as standard are maximum and minimum peak values, totalization and data logging, RS485 Modbus RTU.
