The set point is adjusted by means of a compressible spring installed in opposition. NC NC NC C C C NO NO NO Set point and reset point must be between 10% and 90% of the selected scale. Standard factory adjustment Setpoint at 50% of the scale on falling temperature NC C NC NC C C NO NO NO Customer specific factory adjustment (option SETP) The following specifications have to be given with the order: • Setpoint value • Adjustment on falling or raising temperature • Dead band value when using an adjustable dead band switch Electrical connections 2 SPDT 1 SPDT NC Blue COM Red NO White NC Blue COM Red NO White NC Blue COM Red Yellow / green NO White NO C Non hazardous area NO or NC NC + Rc 1 Supply – Screen For max. ambient temperature refer to technical data on page 1. The installation must be made in an intrinsically safe circuit whose certified electrical safety parameters do not exceed any of the values Umax, Imax and Pmax given in the electrical data on page 1. All necessary measures must be taken by the user, to avoid the calorific transfer from the fluid to the apparatus head increasing the head's temperature to such that it reaches the self-ignition temperature of the gas in which it is used. www.baumer.com Data sheet B31.11 Page 2 / 5 2015-04-14 Certified safety barrier Hazardous area Zone 0, 1, 2 Design and specifications subject to change without notice Yellow / green RTNY3 - RTAY3 Industrial temperature switch, direct mounting with intrinsic safety Micro switches characteristics Switch code N (T) M (K) C (W) S Type Tropicalized Gold contact Hermetic Ultrasensitive Gold contact 6 Vdc 0.1 ... 0.12 A 10 ... 50 mA 5 ... 120 mA 10 ... 50 mA 12 Vdc N/A 10 ... 50 mA 5 ... 66 mA 10 ... 50 mA 24 Vdc N/A 10 ... 33 mA 5 ... 33 mA 10 ... 33 mA 30 Vdc N/A N/A N/A N/A 48 Vdc N/A N/A N/A N/A 110 Vdc N/A N/A N/A N/A 220 Vdc N/A N/A N/A N/A 115 Vac N/A N/A N/A N/A 250 Vac Dielectric rigidity between contacts and ground N/A N/A N/A N/A 2000 V 2000 V 1500 V 2000 V Adjustable ranges Micro-switch dead band 1) TMax Scale accidential °C Adjustable dead band Code °C N (T*) M (K*) 10% 90% Fixed dead band C (W*) 10% S 90% 10% 90% °C 0 40 300 4-9 2-9 8 - 12 4 - 12 3 2.5 -20 ... 20 60 301 3-8 1.5 - 8 6 - 12 4 - 12 2.5 1.5 0 ... 45 60 302 4-9 2-9 7 - 12 4 - 12 3 2 40 ... 120 145 303 5 - 16 3 - 16 10 - 20 6 - 20 4 3.5 20 ... 80 100 315 5 - 12 3 - 12 9 - 15 5 - 15 4 3 -46 ... (*) For version with 2 microswitches lower values of the dead band must be multiplied x 1.5 The value of the dead band is depending on the value of the set point. This table contains the dead band values for set point adjustment at 10% and 90% of the selected scale. For adjustable dead band the lower value corresponds to the dead band spring totally released and the higher corresponds to the dead band spring fully tensed. For other set points the dead band value can be calculated by linear interpolation between the values at 10% and 90%. 2015-04-14 Design and specifications subject to change without notice 1) www.baumer.com Data sheet B31.11 Page 3 / 5 RTNY3 - RTAY3 Industrial temperature switch, direct mounting with intrinsic safety Dimensions (mm) 76.5 = 125 = 58 130 100 28.5 64 144 139 5 45° 130 Thermowell 144 Thermowell for RTxx3 Stainless steel Ordering code : 10271317 20 Hex 29 22 G 3/8 70 103 P= 135 3/4 BSP.TR Ø 18X16 2015-04-14 Design and specifications subject to change without notice Ø 14 www.baumer.com Data sheet B31.11 Page 4 / 5 RTNY3 - RTAY3 Industrial temperature switch, direct mounting with intrinsic safety Ordering details RTNY3-RTAY3 RT Model Industrial temperature switch RT Type of the bulb Copper alloy bulb Stainless steel bulb Approval ATEX intrinsic safety Type of micro switches 1 SPDT hermetically changeover switch 2 SPDT hermetically changeover switch 1 SPDT gold contact changeover switch 2 SPDT gold contact changeover switch 1 SPDT tropicalized changeover switch 2 SPDT tropicalized changeover switch 1 SPDT ultrasensitive gold contact changeover switch Y – . 3xx .
