Industrial data diode designed to deliver the highest level of security to OT networks like industrial control systems (ICS) and safety critical infrastructure via physical isolation when there’s a need to connect them to a lower security network (IT Networks or Internet) for replication or analytics.

 

The DCU is designed and manufactured in Germany, its chip design forces data to flow one-way only using a unique electromagnetic induction design, to collect data and guarantee that there’s no physical path for remote access to the OT Network.

 

The DCU has a software complement called, OWG (One-way gateway) software, its two agents, a OWG sender capable of data collection of several protocols (FTP, OPC UA, Syslog), filtering and aggregating data in the OT network (Edge) to then push it thru the DCU and a OWG receiver, which receives data from the DCU and can be configured to send it directly to the cloud (AWS or MindSphere) or to another computer in the IT network.

 

The DCU and OWG are vendor neutral and support Windows or Linux systems.

SIRIUS 3RA6 compact starters are universal motor feeders according to IEC 60947‑6‑2. As control and protective switching devices (CPS) they can connect, convey and disconnect the thermal, dynamic and electrical loads from short-circuit currents up to Iq = 53 kA, i.e. they are practically weld-free. They combine the functions of a motor starter protector, a contactor and a solid-state overload relay in one enclosure. The 45-mm-wide direct-on-line starters and 90-mm-wide reversing starters are available as variants. Applications SIRIUS compact starters can be used wherever standard three-phase motors or resistive loads up to 32 A (approx. 15 kW/400 V) are directly started or switched. The compact starters are not suitable for the protection of DC loads. Approvals according to IEC, UL, CSA and CCC standards have been issued for the compact starters. Very high operational reliability The high short-circuit breaking capacity and defined shut-down when the end of service life is reached means a very high level of operational reliability that would otherwise have only been possible with considerable additional outlay. This sets the SIRIUS compact starter apart from devices with similar functionality. Safe disconnection The auxiliary switches (NC contacts) of the 3RA6 compact starters are designed as mirror contacts. This enables their use for safe disconnection - e.g. EMERGENCY-STOP up to SIL 1 (IEC 62061) or PL c (ISO 13849-1) or, if used in conjunction with an additional infeed contactor, up to SIL 3 (IEC 62061) or PL e (ISO 13849-1). Permanent wiring/easy replacement Using the SIRIUS infeed system for 3RA6 it is possible to carry out the wiring in advance without a compact starter needing to be connected. A compact starter is very easily replaced simply by pulling it out of the device without disconnecting the wiring. Even with screw connections or mounting on a standard mounting rail there is no need to disconnect any wiring (on account of the removable main and control circuit terminals) in order to replace a compact starter. Benefits:

• Compact design saves space in the control cabinet
• Little planning and assembly work and far less wiring thanks to a single complete unit with one article number
• Low variance and therefore low stock levels, with two wide voltage ranges and five wide setting ranges for the rated current
• High plant availability through integrated functionalities such as prevention of main contact welding and disconnection at end of service life
• Enhanced productivity through automatic device reset in case of overload and differentiated detection of overload and short circuit
• Easy checking of the wiring and testing of the motor direction prior to start-up thanks to optional control kits
• Speedy replacement of devices thanks to removable terminals with spring-loaded and screw connections in the main and control circuit
• Efficient power distribution through the related SIRIUS infeed system for 3RA6
• Direct connection of the motor feeder cable to the SIRIUS infeed system for 3RA6 thanks to integrated PE bar
• Connecting and looping through incoming feeders up to a cross-section of 70 mm²
