Jumo 00572502 Temperature limiter
The Ex safety temperature limiter and monitor in accordance with DIN EN 14597 has a power supply range from AC/DC 20 to 30 V, 48 to 63 Hz. With the use of the compact and freely configurable STB/STW Ex, potential hazards in the hazardous area, which lead to injury to people or damage to the environment as well as destruction of production plants and production goods, can now be detected early and safely. The devices are available in the 2 designs. 1-sensor version 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 version 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 heat engineering processes and putting the equipment in a safe state in the event of a malfunction. The device has the approvals according to DIN 14597, IEC and IECEx as well as the approval according to ATEX and is thus also applicable in Ex-areas. The inputs are intrinsically safe [Ex ia] according to EN 60079-11, so that the corresponding sensors can be connected directly. The use of a barrier is no longer necessary. Similarly, the device is certified in accordance with 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 the monitoring of explosive atmosphere of gas and dust. The high requirements of the DIN EN 61508 or DIN EN 13849 are fulfilled by a device concept, which with its 1oo2D structure leads to a safe detection of errors and can therefore also be used in applications which are based on the new Machinery Directive 2006/42/EC. The brilliant and clear structured display with plain text display and background lighting in connection with the keyboard provides for a fast and easy configuration directly at the device. The clear menu structure enables the user a safe handling of the device and thus reduces the start-up time. All safety-relevant process values are displayed and the most important functions are displayed using simple pictograms. Two universal analogue inputs, a digital input, two relay outputs with a switching power of AC 230 V, 3 A, 50 Hz and a universal analogue output are available.This text is machine translated.
