The Ex - safety temperature limiter and monitor according to DIN EN 14597 has a voltage supply range of AC 110 to 240 V + 10 / -15%, 48 to 63 Hz. With the use of the compact and freely configurable STB / STW Ex, potential dangers in the Hazardous areas that lead to injuries to people or damage to the environment, as well as the destruction of production facilities and production goods, can be detected early and safely. The devices are available in two versions. 1-sensor variant Ex II (1) (2) (3) G (b1) [Ex ia Ga] [e pz] IIC, Ex II (1) (2) (3) D (b1) [Ex ia Da ] [p Dc] IIIC. 2-sensor variant Ex II (1) (1) (2) G (b2) [Ex ia Ga] [e py] IIC, Ex II (1) (1) (2) D (b2) [Ex ia Da ] [p Db] IIIC. Safety temperature limiters have the primary task of safely monitoring thermal processes and putting the systems in a safe operating state in the event of a fault. In addition to the approvals according to DIN 14597, IEC and IECEx, the device also has ATEX approval and can therefore also be used in Ex areas. The inputs are intrinsically safe [Ex ia] according to EN 60079-11, so that appropriate sensors can be connected directly. The use of a barrier is no longer necessary. The device is also certified according to DIN EN 50495 and DIN EN 13463-6 as ignition source monitoring (iPL 2) in the sense of the ATEX directive and can be used for monitoring explosive atmospheres of gas and dust. The high requirements of DIN EN 61508 and DIN EN 13849 are met by a device concept which, thanks to its 1oo2D structure, reliably detects errors and thus also in applications that are based on the new Machinery Directive 2006/42 / EC. can be used. The brilliant and clearly structured display with plain text display and backlight in connection with the keyboard ensures quick and uncomplicated configuration directly on the device. The clear menu structure enables the user to handle the device safely and thus shortens the commissioning time. All safety-relevant process values ​​are displayed, the most important functions are represented by simple pictograms. There are two universal analog inputs, one digital input, two relay outputs with a switching capacity of AC 230 V, 3 A, 50 Hz and a universal analog output.
