DYNAPAR brand Process Indicators & Controls
S428 Intelligent Process Meter Volts, Current, Thermocouple, or RTD Process Measurements with Intelligent Features… available with red or green LED display
The Dynapar brand S428 Process Meter can display a wide variety of process input signals while providing a host of intelligent features. Housed in an industry standard 1/8 DIN case, the S428 is field configurable to accept standard DC current or voltage process signals as well as most thermocouples and RTDs. Its 0.56" high LED display, available in red or green, is easily scaled through the front panel to display in engineering units. Standard with a relay alarm output, other functions can be installed at the factory or later in the field. Choose from additional alarm relays, an auxiliary power supply for use with the input transmitter/sensor, a remote alarm reset, a DC output for retransmission to a strip chart recorder or PLC. ■ Universal input capability: DC Process Volts, Current, and Temperature ■ Quick and easy front panel input scaling ■ Field interchangeable outputs provide flexibility and minimize downtime ■ Up to three alarms fully configurable for High or Low operation ■ Max and Min value capture provides valuable process information

■ Serial communications for interface to a host device ■ NEMA 4/IP65 rated front panel for use in washdown environments ■ Transmitter power supply simplifies wiring ■ Universal AC power supply An optional RS-485 serial communication board supports Modbus or open ASCII protocol. Alarm outputs can be field configured for high or low operation and combinational logic. Its unique accumulated alarm time function tells how long the alarm condition has been present. Other key process monitoring features include process value offset, and programmable input filtering.
