Our achievements
PWR-UPS24120 PWR-UPSBH
UPS system for managing 24Vcc utilities with advanced battery monitoring. Specific automatic tests to determine its health status. 3 fully configurable relay alarms and the possibility of sending alarms and battery electrical measurements through the IEC-60870-5-104 and MODBUS/TCP protocols (with optional Ethernet interface). In this way, the device interfaces directly with the supervisory SCADA systems.
Intuitive configuration interface (GUI) for fast alarm programming.
The system can be supplied standalone precisely pre-mounted on a convenient full wiring plate for 7Ah or 18Ah AGM batteries.
Fan Load Controller - PWR-LDC2400
​Diagnostic module for ventilation systems installed in electrical panels.
Cooling of the internal components of electrical panels is normally entrusted to electric fans that start up controlled by a thermostat.
However, there is no guarantee that when the contact is closed the fan will begin to perform its task.
Systems based on airflow interception are often ineffective because they are influenced by the same causes capable of blocking fans, such as dirt, dust, or small animal carcasses.
If the fan does not start, the temperature increases and can reach the operating limits of the components. High temperature alarms go off when there is already a critical situation.
PWR-LDC2400 (Patent Pending) offers a diagnostic function based on the analysis of the current drawn by the fan motor and is capable of detecting:
Rotor stuck or slowed down
Open circuit
Irregular rotation
The alarm condition is made available both through a potential-free contact and through the IEC60870-5-104 protocol. This makes
PWR-LDC2400 perfectly integrable into existing SCADA.
Setup is extremely simple, thanks to the built-in CLI (command line) and even more effective user GUI.
GTW-ASP2400
GTW-ASP2400 is a multifunction device that effectively solves many interconnection issues in SCADA/automation environment. It is equipped with 4 RS-232 serial ports, one of which is dedicated to configuration, and an Ethernet interface (optional).
Based on the chosen configuration, GTW-ASP2400 can perform the following functions:
-
COM2TO1 2-in-1 serial splitter: Two MASTER devices (Active / Reserve) communicate with a line on which one or more slaves are attested (Typical situation of a SCADA system connected to a line of RTUs).
-
COM1TO2 1-in-2 Serial Splitter: A remote RTU has two communication ports, but communication is handled through a single communication line.
-
ETH1TO2 1-in-2 Ethernet Splitter: An RTU has dual network cards, with separate IP addresses, but the SCADA system can handle a single IP address.
-
IEC104-1: Direct protocol conversion between IEC60870-5-104 and 101 (MASTER-SLAVE).
-
TSERVER RFC2217: Serial server according to the RFC2217 specification
-
RAW TSERVER: Serial server in RAW DATA mode
​
The "micro RTU" mode allows systems interfacing with GTW-ASP2400 to have diagnostic information about the device through the IEC60870-5-101/4 protocols and to send some control commands (port switching, reboot) to the device.
When used in serial mode, GTW-ASP2400 is independent of the protocol used. In EIA RS-232 mode it automatically routes both bidirectional and unidirectional RTS/CTS modem signals.
The three communication ports dedicated to data diversion can be configured either as DTE (Data Terminal Equipment) or DCE (Data Communication Equipment). This feature greatly simplifies wiring by allowing serial cables to be made exclusively pin-to-pin.
Powersafe Industrial IDC (Ideal Diode Controller)
In many industrial applications, equipment power is redounded to increase system availability and reliability. Traditionally, power buses are connected to each other via power diodes.
Powersafe Industrial IDC is an ideal diode controller designed to replace parallel diodes.
Thanks to the very low voltage drop, there is no dissipation of power into heat, which reduces consumption by 80% compared to traditional diode solutions.
The entire system is supervised by a microcontroller that constantly checks the module status and the current draw from the load. Any anomaly is reported externally by two potential-free contacts that can be acquired by the SCADA system.
The module installs on a DIN rail and wiring quickly thanks to the removable terminal blocks. It can also be replaced in live circuits.
GPS-ASY2400
In most industrial applications, it is essential to be able to reconstruct the timing sequence of events that occurred at the plant.
The physical acquisition of state variations, however, is carried out by different devices, each with its own clock characterized by a certain intrinsic and non-eliminable drift. It is therefore necessary to install a reference device, capable of distributing the exact time to the devices that need it.
The GPS-ASY2400 is an ultra-compact, low-cost synchronization device that is configured as a true time server.
Time information can be sent to devices either through the widely used NTP protocol or through other technologies, such as the "Data Time String" and IRIGB.
The generated IRIGB signal is available in the form of TTL electrical levels both through an RS485 interface.
As with all other products, the power supply is dual to ensure maximum availability and reliability.
The Run Time Clock is equipped with a user-replaceable lithium battery that, in the absence of power, maintains the date and time for up to 240 days.
