Machine diagnostics via text message Murrelelektronik has introduced MIRO GSM, a control cabinet component that communicates with plant operators via text message. Not only does this provide up-to-date machine operating conditions with a short message, but the oper- ator can control the outputs via text message. Using the components, it is possible to mon- itor and control six analogue or digital inputs and four relay outputs with C/O contacts (250V, 10A) with text message using the GSM cellular network (850, 900, 1800, 1900 MHz). The settings for MIRO GSM are done at the computer with configuration software. For the analogue inputs you can define additional lim- its for sending a message; and, if a digital sig- nal changes or an input limit is reached, a predefined text message is sent. Up to 50 cell phone numbers or email addresses can be stored in the integrated phone book, and an acknowledgement function ensures information is received. If needed, the plant operator can change four relay outputs with a text message or a toll free call to shut down a machine or to switch air handling units or lighting systems on/off. MIRO GSM is available in models with 12-48V DC and 110-230V AC. Murrelelektronik

New from Micromech is the Kollmorgen P5000 stepper drive, which is optimised for high system performance particularly when used with the POWERMAX II stepper motors. Features include a current output from 0.7-3.5A peak that is DIP switch selectable in 0.2 Amp increments, Bus Voltage 20-75 V DC and wave matching via potentiometers for Kollmorgen motors to provide optimal performance. All the inputs and outputs are similarly optically isolated, and the command source from external step/direction inputs or internal velocity controlled oscillator (VCO) is DIP switch selectable. The VCO mode allows for velocity control via two separate potentiometers for CW and CCW rotation and a third potentiometer for acceleration. Micromech

Two ranges of splitter boxes with M8 sockets have been launched by ifm electronic. These will operate between -25 and +80˚C.
The EBC range includes four and eight- way connections for
M8 (to EN61076) with either 3-pin or 4-pin configuration. They

are equipped with local LED indica- tion. The EBC M8 splitters can be sup- plied with integral 5m or 10m multicore cable for connection back to the panel. Alternatively, the
4-way versions can be ordered with an M16 connector and
plug-in home-run cables. There are three versions for AS- interface: AC2484 is a 4-input unit, AC2482 features two inputs and two outputs, while AC2488 is a single slave for eight inputs. All the AS-i M8 modules feature an M12 connector to the network and do not require additional power. ifm electronic T: 020 8213 0000
Enter 246 New solutions help to identify and mitigate power issues
Rockwell Automation has expanded its Allen‑Bradley power quality portfolio to include the i-Sense monitoring solution, i-Grid service and DySC dynamic sag corrector. These scalable solutions help OEMs and end users identify and mitigate power issues to improve uptime and productivity, explains the company. The first step toward improved performance is identifying any power quality issues affecting electronic equipment. The i-Sense voltage monitors reads incoming power for the entire facility and provides data that pinpoints voltage-based power events, reveals any consequent relationship between voltage sags and downtime situations, and helps users get operations running with minimal mean time to repair (MTTR).
The subscription-based i-Grid service logs, analyses and corroborates i‑Sense data via an Ethernet or modem connection from in and around facilities to confirm if power-quality issues were the result of a grid event. The DySC dynamic sag corrector uses double-conversion inverter technology to protect against brief voltage sags and momentary outages. Customers can scale the DySC corrector from 0.25 kVA to 2000 kVA, offering machine- to facility-wide protection. The corrector provides 100% sag protection in a relatively compact size and without batteries, compressors, pumps or flywheel bearings. Optimised for fast response at voltage peaks, the DySC corrector has a typical peak voltage detect time (pVdT) of one millisecond and can provide a facility continuous, uninterrupted power for up to five seconds.

circuit breaker A new miniature circuit breaker (MCB) in accordance with EN 60947-2, is now available from E-T-A Circuit Breakers.
Designed for DIN-rail mount- ing, the 4230-T thermal-magnetic MCB is toggle actuated and features a positive, trip-free, snap- action mechanism for reliable switching behaviour. It offers visual status indication and high rupture capacity and can be specified from a range of trip characteristics with optional add- on modules. The MCB is suitable for the protection of cables, motors, generators, transformers, thyristors and silicon rectifiers; and of industrial process control systems, telecommunications equipment, power suppplies etc. The device is offered in current ratings, from 1A up 63A, with single pole protection at 230V AC or from 2 to 4-pole protection at 400V AC.

New miniature New hydraulic linear actuation system
Now available from Albert Jagger is Bansbach’s Easymotion, an hydraulic linear actuation system that offers synchronous control of multiple adjustment cylinders. This enables accurate positioning and height/level adjustment of equipment, machinery or surfaces to user specifications. Consisting of hydraulic pump, adjustment cylinders and flexible tubes for connecting each component, the system can be oper- ated manually via a foldable crank handle or electric motor. There are also a wide range of control systems available to operate the electric motor, including push button, foot pedal and remote control options. The loading and speed of the system can be set subject to specifica- tion and size, and the system is said to be very easy to install, making the siting and adjustment of vertical, horizontal and angled surfaces quick, easy and accurate. Typical applications include workstations, monitors or screens, assembly tables, production line facilities, as well as disability, rehabilitation and medical/laboratory equipment. A heavy duty version is also available which can move loads up to 900kg. This consists of four adjustment cylinders and is operated by an electric motor. The compact dimensions of the hose connectors between the pump and the adjustment cylinders mean that the system can be installed into even the smallest space.
In the event of a problem, misuse or obstruction, the ‘break-stop’ system will safely shut off the power and stop the procedure. This can also be specified as an option on all standard Easymotion systems. Albert Jagger
