IX58 – CX58 ATEX encoders complement the XC77 series of ATEX incremental encoders that are category 2 com- pliant and intended for use in Zones 1, 2, 21, 22 and in the temperature class T6 (T85°C). IX58 - CX58 are especially distingui- shed by the wide choice of mechanical and electrical con- nection options, so they can easily suit a large number of nor- mal industrial uses. From a mechanical point of view they feature a compact 58 mm diameter in- dustrial enclosure with IP65 protection rate; furthermore they are designed in a complete range of mechanical mo- dels: you can choose either from the Ø 6, 8, 9.52, 10 and 12 mm (0.24”, 0.31”, 3/8”, 0.39”, 0.47”) solid shaft versions with servo or clamp flange mounting; or from the Ø 14 and 15 mm (0.55”, 0.59”) blind hollow shaft versions. IX58 - CX58 offer increased electrical protection and safety systems according to ATEX yet they keep maximum versati- lity and adaptability. They are available in both digital and analogue interfaces: single-channel or quadrature digital signals are provided via NPN, PNP, Push-Pull, Line Dri- ver and Universal output circuits with resolutions up to 10000 PPR; the analogue interface is the 1Vpp type with resolutions from 500 to 2500 PPR. The permissible counting frequency can be up to 300 kHz. The ATEX encoders have axial and radial cable output with length on request. An overcurrent protection is installed in all interfaces and complemented by the reverse polari- ty protection and the short-circuit pro- tection at output in specific interfaces. IX58 - CX58 encoders guarantee an increa- sed safety level in all industrial environ- ments where an oc- casional risk of a gas and dust explosive mixture may occur. Lika Electronic introduces a complete series of ATEX category 3 incremental encoders: they are intended for use in potentially explosive zones 2/22 and offer the broadest range of connection options.

Extending the range of ATEX incremental encoders

Lika Electronic widens the ATEX product range and intro-duces the new series of IX58 - CX58 category 3 incre-mental encoders. Category 3 comprises the products de-signed to meet the requirements of the new 2014/34/EU European Directive (also referred to as “new ATEX Directive”) and suitable for a safe use and a normal level of protection in areas in which explosive atmospheres caused by mixture of gases and vapours (zone 2) or dust (zone 22) are unlikely to occur and if they do occur do so for a short period of time.

SIL3/PLe safety controller for functional safety of incremental encoders

Safety is becoming increasingly important in the design and manufacturing of machi-nes and plants. It is intended to safeguard the health of workers on one hand; and to improve productivity, efficiency and relia-bility on the other hand. So more and more often functional safety systems are im-plemented: they use certified subsystems in order to fulfill specific and unavoidable safety requirements.IFS-10 safety controller from Lika Electronic is conceived to exactly meet this need: it is designed for the integration of incremental encoders (and even “non safe” encoders) into systems that require the SIL3 Safety Integrity Level and the PLe Performance Level. Thus it is ideal to retro-fit existing industrial plants.SIL and PL are two different methods that allow for evaluation of a safety function: they are defined by the EN 62061 (SIL) and ISO 13849-1 (PL) standards and achieve similar results (so they are often matched together). SIL3 and PLe are the higher levels of safety for machinery.

IFS-10 is SIL3/PLe certified and allows to create a redundant safety subsystem by means of sin/cos 1Vpp, HTL/Push-Pull and TTL/RS422 incremental encoders, but also proximity sensors, limit switches and command devices. It monitors and controls speed, standstill and direction of rotation in single axis applications and im-plements the following safety functions in compliance with the EN 61800-5-2 stan-dard: SLS, SSM, SS1, SS2, SOS, SDI.

IFS-10 connects at input two incre-mental encoders or a single redundant encoder (for instance the magnetic SGSD) with either sin/cos or Push-Pull or RS422 interface, but also switches and sensors; they can be freely paired to achieve re-dundancy. The motion controller provides the following safety outputs, program-mable according to needs: 1 sin/cos splitter output, 1 RS422 splitter output, 1 force guided redundant relay output (NO), 4 HTL inverse redundant control outputs and 1 4-20mA analog output.

The set up of all functions and the parame-trization of the input and output features is fast and intuitive by using either the PC software tool via USB supplied for free or the optional keyboard: the additional mo-dule is fitted with an OLED display and is even removable and allows for user-frien-dly configuration and comprehensive dia-gnostic information.Two LEDs for status monitoring and the clip for DIN rail mounting are a further ad-vantage. The enclosure is sound and com-pact (50 mm W x 100 H x 160 D).Because of its great versatility and the bro-ad compatibility IFS-10 is perfect both for installation in modern certified au-tomation systems and for the retrofit of outdated plants and in applications such as the automation of stage machinery, swi-velling platforms, cranes, hoists, steel mil-ls, working machines, conveying systems, wind turbines.
