The µACP 2040 HT control unit, with its ultramodern hardware and software features, is state-of-the-art in the field of industrial/plant automation. The LCD 10.4” display with touchscreen ensures maximum functionality and flexibility. The great versatility and scalability of the hardware sub-system allows its application as both stand-alone process controller and RTU within distributed intelligence networks of different types. Effective external communication is made possible by the most modern transmission systems (TCP/IP, GSM/GPRS, Fieldbus). The integrated Microsoft Windows Embedded™ operating system enables the control unit to host complex SCADA systems and operate as local Control Centre in high level telecontrol networks, without the need of intermediate PC stations. The absence of critical moving parts makes this machine particularly suitable for areas subjected to high operating stress, ensuring maximum service continuity even in industrial environments. It is suitable for panel or wall mounting (with fastening accessories).

The peripheral device SK 2040 GSM ALARM allows:

The monitoring of up to 8 analogue inputs, with the possibility of programming two thresholds per input and sending an SMS alarm as soon as such thresholds are exceeded.
The monitoring of 8 digital inputs that can be set up as an alarm or a counter
Alarm configuration: the peripheral device sends an alarm via SMS when the conditions changes and issues a notification when these are brought back to normal. One of the digital inputs may be independently configured as an alarm for power failure in the mains power supply (in this case, a buffer battery will necessary – optional accessory).
Counter configuration: it allows to monitor the pulses coming from totalisers or event counters and to store the total count at set time intervals.
To remotely modify the status of the 4 available relays: following a command (that can be sent also via SMS), the peripheral device modifies the relay activation status.
To request report messages: the peripheral device can be configured to send an SMS informing on the current conditions of the relays and inputs (both analogue and digital), as well as notifying possible alarms.
To set up to 5 different telephone numbers to send alarms via SMS: it is possible to create a specific text message for each signal, in order to make it easier to read it. The “VOC” version, which allows to send pre-recorded vocal messages, is also available.
To store up to 12,000 recordings and create a chronological log in text format: recoding can take place according to programmable time intervals and/or events. The acquired data can be download on a local PC via the USB port or sent via MODEM to a remote control centre. The configuration of the control unit and the download of the stored data can only be carried out with the software tool supplied as an accessory, using a normal PC provided with a USB serial port and the Windows operating system.

Available software versions
Vocal: it allows to record up to 4 alarm messages, as an alternative to the SMS mode

Master-Slave: it allows to use a control unit for point to point automation, in order to generate spontaneous calls for the activation/deactivation of a relay

Low-Power: it allows to use the control unit as a data logger with very low consumption (for battery power supply in absence of mains power supply)

Data Logger: without GSM; only to record, view and download data.

GPRS: it allows to use the control unit as part of a bigger centralized telecontrol network, where data are exchanged via TCP/IP protocol.

Increase in the signal number: through the serial port RS 485, it is possible to connect the control unit to other cards, in order to increase the number of manageable I/O signals.

SK 2040 GSM ALARM – MASTER/SLAVE version

The MASTER/SLAVE version of the SK 2040 GSM ALARM peripheral device allows to manage the status of a remote unit relay according to the status of an input of the remote unit itself. For instance, it is possible to use a pair of SK 2040 GSM peripheral devices to automatically control a pumping station whose location is remote from the tank: when the water level decreases a level switch will notify the peripheral device on the tank. This will call via modem the peripheral device on the pumping station to activate the pumping. On the contrary, when the water in the tank reaches the
established level (the status of the level switch changes), its peripheral device stops the pumping by calling again the peripheral device of the pumping station.
For this purpose, it is possible to set up the number of relays to be controlled through the remote peripheral device (up to 4 separate pumps of a pumping station from 4 separate tanks), the number of call attempts to be carried out in case of communication issues (line engaged, lack of GSM signal, etc.), as well as the time interval between each call. In the event that all attempts to transmit the command fail, it is possible to program the sending of an SMS to notify that the activation was not successful.
