1.1 - Description
Presys
Auto-Manual / Auto / Manual
instruments for application in Instrumentation and Process Control.
They can communicate with computers by optional communication module
RS-232 or RS-422/485.
The Auto-Manual / Auto / Manual Stations have been designed according to
modularity and flexibility concepts. Both the Single Loop Station and Dual Loop Station,
have a variety of standard output types, such as: voltage (1 to 5V, 0 to 10V) and current
(4 to 20mA).
They are capable of monitoring two standard inputs: current (4 to 20 mA) and
voltage (1 to 5V and 0 to 10V).
A 24VDC voltage source, isolated and with short circuit protection, is provided for
transmitter power supply.
The type of input selected by the user is enabled by jumpers and by the software
configuration. All configuration data can be protected by a password system, and are
stored in the non-volatile memory in the event of a power failure.
They accept 90 to 240VAC or 130 to 340VDC (with any polarity) power supply.
Other ranges are also available.
The instruments are housed in an extruded aluminum case which makes them
highly immune to electrical noise, electromagnetic interference and resistant to the most
severe and rough industrial use conditions.
On the instrument front panels there are two red displays jointly configurable with
the decimal point for up to four high visibility digits. The function of the UP, DOWN and
