Dynapar's S428 Intelligent Process
Meters: The
Dynapar brand S428 Process Meter can display a wide
variety of process input signals, such as volts, current,
thermocouple, or RTD, while providing a host of
intelligent features. Housed in an industry standard 1/8
DIN case, the instrument is field configurable to accept
standard DC current or voltage process signals as well as
most thermocouple 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. 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 max and min value capture,
process value offset, and programmable input filtering. A
universal AC power supply meets global requirements, and
an EEPROM retains all data when power is not present.

JOHNSON CONTROLS
SYSTEM 350

The System 350 Control
Series by Johnson Controls is a modular, electronic series
encompassing a wide variety of ON/OFF and proportional
temperature, humidity, and pressure applications, as well
as temperature reset. The basic system consists of a
control module, which accepts stage, display, and
transformer modules. A variety of temperature, pressure,
and humidity sensors are also available. Hundreds of
different control systems can be configured using a
combination of the controls and their accessories.
Five-pin connectors eliminate wiring between modules,
minimizing installation costs, and reducing wiring errors.
The modules can be DIN rail or surface mounted. Up to nine
stages (ten total relays) are possible for full
functionality. UL and CSA approved, and Pacific Controls
has a good stock of these controls for your application. |
