DatasheetDynisco 1490 5-Digit 1/8 DIN Indicator
The Dynisco 1490 is a universal 5-digit indicator in a 1/8 DIN format for displaying different process signals. It is suitable for plastics processing and industrial measurement systems where process values such as pressure, temperature or other analog signals need to be displayed and monitored reliably.
The universal input supports thermocouples, PT100, strain gauge sensors and DC linear signals. This allows the indicator to be flexibly adapted to different sensing and measurement tasks. Values are displayed on a bright 5-digit 13 mm LED display, supported by status indications for up to two alarms as well as minimum and maximum values.
The Dynisco 1490 can optionally be equipped with analog output, transmitter supply and Modbus communication. This allows process variables to be retransmitted to other devices, sensors to be powered directly, or the unit to be integrated into higher-level systems via an RS485 interface. Two process alarms with adjustable hysteresis support simple limit monitoring.
