FOREWORD
The unit is manufactured, checked and supplied in
accordance with our published specification, and when
installed and used in normal or prescribed applications, with
the lid in place and within the parameters set for mechanical
and electrical performance, will not cause danger or hazard
to life or limb.
Warning: Units must be selected and installed by
suitably
accordance with appropriate codes of practice so
that the possibility of failure resulting in injury or
damage caused by misuse or misapplication is
avoided.
Warning:
instrument characteristics comply with process and
plant
Warning: The users attention is drawn to the fact
that, when the unit is 'live' with respect to electrical
or pressure supplies, a hazard may exist if the unit is
opened or dismantled
Warning: where any special condition of the product
has been required as identified by the last 4 digits of
the part number, follow the necessary safety
instruction for a correct installation.
If the equipment is likely to come into contact with aggressive
substances, suitable precautions should be taken that prevent it
from being adversely affected, thus ensuring that the type of
protection is not compromised. Aggressive substances: e.g.
acidic liquids or gases that may attack metals or solvents that
may affect non-metallic materials. Suitable precautions: e.g.
regular checks as part of routine inspections or establishing
from the material's data sheet that it is resistant to specific
chemicals.
OVERVIEW
Indicator DMCU800 is a low multifunctional programmable
controller. Its universal input accepts the most common
RTDs, thermocouples and linear signals. The device can be
equipped with up to 5 relays outputs, which can control
various actuators using ON/OFF control algorithm. Тhe
controller can be equipped with an additional analog output
operating in retransmission mode and the optional RS485
interface enables networking. Indicator 37003754 allows
adjusting of the built-in digital filters and the programmable
output delay, resulting in increased operation reliability in
case of industrial interferences. In addition, the device
performs a specific function such as a linear-segment
transformation with up to 30 points. The functionality has
also been improved with regard to the diagnostics of failures
with programmable states of the relays and analog outputs,
depending on the type of the errors - measuring or
parametric system .
