Controller has myriad applications
F
RAMOS ELECTRONICS, an established supplier of image processing systems, and Smartek, a Croatian electronics company, have announced high-end LED illumination controllers for professional applications. Smartek’s Strobe Controller (SC) series is use for industrial machine vision applications. Latest models have Ethernet or RS232 control interfaces, with full SDK support for both Windows and Linux operating systems. The family of strobe controllers features 1, 2, 4 or 6 parallel channel options, both digital and analogue light head coding, an integrated temperature sensor and built-in power supply – all supplied in an industrial and compact anodised aluminium case. They can deliver high power pulses of up to 8A and 200V per channel at 1µs pulse duration. Pulse duration is also widely variable from 1µs to 1000ms and with low trigger latency and very low jitter. Inline current and voltage measurements ensure the lighting is never overdriven to damaging levels.
Nord provides the inverter types SK 515E and SK 535E in the new size. The units enable out-of-the-box implementation for many standard industrial applications. Equipped with five parameter capable control inputs, two analog inputs, and one analog output as well as two relay outputs, the SK 515E provides many connection options for users. The SK 535E additionally features two analog inputs and two output channels.

The supplied software provides a simple interface to control and manage each output channel individually plus the triggering parameters. Triggers are rising edge 0-5V or 0-24V with either positive or negative edge.

New inverters added to Nord range
U
SED IN many industries with the potential to find applications within converting and packaging, Nord Gear drive systems will shortly add new models to its SK 500E series of cabinet- mounted frequency inverters.
The new size 7 inverters cover rated motor outputs between 30 and 37
kW. Models with even larger dimensions are already being planned. Just like all previous models, the new inverters are available with various feature kits, whilst retaining standard sizes regardless of the functional range.

Standard features for all SK 500E inverters include sensor-less current vector control, automatic parameter identification for connected motors, an integrated brake chopper for generative operation, PID process control and four parameter sets that can be switched online. Furthermore, the control card can be supplied from an external 24 V source in SK 515E and SK 535E inverters, which allows access to parameters and the bus interface even when the power is switched off. This feature not only increases online availability, but also enables special applications such as emergency evacuation of elevators. Both size 7 inverters support the safety function ‘Safe Stop’ in compliance with EN 954-1 and EN 13849-1 (up to the maximum safety category 4, stop category 0 and 1) and feature an onboard CANopen interface. In addition to the extensive I/O equipment mentioned above, the SK 535E model also comes with a TTL input for speed and torque control, and provides powerful position control functions thanks to the POSICON module.

System upgrade helps papermaker break record
T
ULLIS RUSSELL, the paper making, coating and converting group, says it has reaped the benefits of turning a vital cog in its manufacturing assets into a record-breaker following a drives and control upgrade undertaken by Optima Control Solutions. Drives, PLCs and SCADA systems are fundamental to keeping the wheels of the Tullis Russell’s production turning, reliant on its machine control systems for production efficiency.
