Input Output Modbus Modules and counters
Types of Variables
- Temperatures: PT100 sensors or thermocouples . directly connected.
- Linear inputs: (4-20 mA or 0-10 V) transduced from external sensors.
- Counts: Low counting (up to 500 Hz) and fast counting (up to 50 khz.)
TYPES OF MODULES
- Acquisition Modules :Used to detect analog and digital inputs. Outputs are not provided.
- Modules with alarms :In addition to the acquisition of the variables ,these modules have digital outputs used to generate alarms configurable by the operator.
The thresholds and the logic of the alarms are entered via operator panels (F1-10, F1-600) and / or supervisory systems (SCADA) through modbus protocol. Both command data interfaces are available .
Din Rail mounting
The hardware structure of these modules (din rail mountable horizontally) compared to traditional solutions (modules mounted vertically), allows you to have a greater number of connectors for the interconnection of field signals. Therefore it’s possible to offer more advanced solutions in modbus technique .The signaling LEDS of electrical magnitudes of both digital input and output have been positioned so as to facilitate the association with the relevant signal. The wiring and the visibility of signals inside the cabinets is facilitated.
The technology of isolation between signal and power supply is very advanced.
In models D1:power supply – RS485 serial bus - acquisition logic are isolated from each other.
( triple isolation )
In models D2: in addition to the galvanic isolation of the models D1, every channel ( Thermocouples and linear signals ) is isolated from each other and from ground.
The Sielco Electronica is one of the few companies to offer this feature to isolate channels between them. This is the best way to ensure the reliable detection of weak signals (eg thermocouples), even in noisy environments.
All products do not require calibration during their life time, keeping unchanged the specific precision and features .
Supervision is provided:
Locally : through alphanumeric panel on dedicated serial (F1-10) for modules with alarm outputs.
At distance ( 1500 m. ): For all types of modules via RS485 HMI operator panel (F1-600) or SCADA with a master Modbus protocol .
Remotely: Using the Internet and commercial software (commercial SCADA systems ).
Sielco Elettronica provides the Modbus libraries for the use of its products.
APPLICATIONS : Sielco Electronica makes available specific applications for each product (easy to use : plug and play ) based on GT05 touch screen Panasonic operator panel, useful in industrial and civil field, ( monitoring, data logging, and energy management ). See section “application”
