High-speed Ethernet extender with switch

Westermo DDW-220 is an Ethernet extender with a built-in four-port Ethernet switch. Existing twisted pair cables can be used to establish a high-speed remote connection between two Ethernet networks. With transfer rates up to 5.7 Mbits/s and with an operating distance of up to 10 km at lower data rates, the unit acts as an alternative to fiber optic or radio systems when linking remote Ethernet networks. DDW-220 uses a transient blocking unit on each DSL line to provide over-current and over-voltage protection on the line, allowing it to handle indirect lightning strike transients, power induction, and short circuit problems. The plug-and-play unit offers data rates from 192 Kbit/s to 5.7 Mbit/s in both directions over distances of up to 10 km. Total galvanic isolation and transient protection are standard for all interfaces. Units are preconfigured for multidrop applications.

Modules for data-logging applications

National Instruments has announced four C Series modules for data-logging applications including vibration/acoustical data logging and in-vehicle, structural, temperature and pressure testing. NI USB-9219, USB-9229 and USB-9239 provide USB, bus-powered connectivity to the C Series, while the NI 9234 ac/dc-coupled dynamic signal acquisition module offers selectable IEPE signal conditioning for engineers measuring high-accuracy audio frequency. The C Series combines signal conditioning, direct sensor connectivity and data acquisition into a small module for each measurement type, which can be inserted into any C Series chassis to create a variety of systems.

High-power variable frequency drives

Danfoss Drives VLT Series variable frequency drives are available with power through 1,350 hp in 460 V and 690 V ac. F1 frame models deliver power up to 1,050 hp in an 86.8 in. x 55.1 in. x 23.9 in. footprint, while F2 frame models deliver up to 1,350 hp in an 86.8 in. x 71.0 in. x 23.9 in. footprint. Components are accessible from the front of each unit, which shares a common platform with smaller Danfoss drives. The Rittal TS8 enclosure system in IP21 (NEMA1) or IP54 (NEMA12) permits easy expansion, while a Class A1 RFI filter (optional class A2) reduces EMI/RFI without external filters; dc-link reactors reduce harmonics without external ac line reactors, and dc-link fuses provide independent protection of inverters.

Ethernet switches stand up to power problems

Ethernet Direct switches will not break open or come off a DIN-mounting when connecting up to 8 Ethernet cables. A rigid aluminum construction provides support and heat dissipation. Switches feature 3,000 V dc EFT power line protection and 4,000 V dc Ethernet ESD (electro static discharge) protection. The standard operating temperature range is -10 to 70 °C. Redundant power inputs enable survival in a single power supply failure. In a failure, an internal fault relay output provides notification and can be monitored by PLC or process systems.

Synthesizer simplifies RF calibration

Fluke Corp. has launched the 9640A-LPN (low phase noise) RF Reference Source, a higher-performance synthesizer developed to simplify RF calibration and improve calibration lab productivity. It joins the company's 9640A model in delivering level precision, dynamic range, and frequency capability in a single instrument to calibrate a range of RF test equipment, including spectrum analyzers, modulation meters and analyzers, RF power meters and sensors, measurement receivers, frequency counters, and attenuators. The 9640A-LPN features integrated signal leveling and attenuation within a precision leveling head.

Analog input modules

Advantech's Industrial Automation Group has announced two input modules. Adam-5017P has eight independent configuration channels, supports power reverse, and has a wide uni-polar or bi-polar input range. Adam-5018P is a thermocouple input module that supports seven input ranges and types (J,K,T,E,R,S, and B), and will filter functions to remove any unreasonable range. Both support the High Common Mode function, which means channel-to-channel differential voltages can go up to 200 V dc. Over-voltage protection helps avoid ranges ± 60 V dc and protects modules from power surges. Built-in TVS/ESD protection is provided for high-density, miniaturization, and complex equipment.

Redundant control system for process industries

Asco has announced an enhanced version of its Redundant Control System (RCS) that supports higher flow rates suited to larger process valve configurations. The company also introduced a new online configuration tool to help customers across a range of oil and gas, refining, and power generation applications select an RCS solution. The RCS achieves higher levels of safety by incorporating a redundant, fault-tolerant architecture, high diagnostic coverage, and automated testing. Its self-diagnostic capabilities test the safety system and process valve to ensure continuous proper operating performance. The system is third-party certified for use in IEC 61508 SIL 3 applications, and it has received system approvals for ATEX Zone 1.

All-In-one palm-size controller

The XL OCS from Omega Engineering is an all-in-one controller for better process visualization and machine control in water treatment, packaging, and agricultural industries. At 3.75-in. square, the XL fits in the palm of a hand and is more compact and affordable than separate PLC and operator interfaces. Features include built-in I/O with removable terminal blocks for easy wiring, a daylight-readable touchscreen, and two serial ports with downloadable protocol. The XL series is the first industrial product to include support for MicroSD memory modules. All XL Series models have a controller, operator interface, networking, and I/O built-in. It is CE compliant.
