Temperature LimiterSenseca Germany GmbH Tenter Weg 2-8 | 42897 Remscheid | GERMANY Phone +49 2191 9672-0 | info(at)senseca.comProduktinformationTemperature Limiter TB225 (in accordance with DIN EN 14597)Temperature limiter:Maximum or minimum monitoring with catch, manual resetting after fault elimination via the front keys or an external switch / voltagesignal. Operating methods in accordance with EN14597: 2012: Typ 2B, 2H, 2VTemperature monitor:Maximum or minimum monitoring without catch, automatic resetting on return to the permissible range.Operating methods in accordance with EN14597: 2012: Typ 2BTechnical data Auxiliary power Auxiliary voltage Power consumption Rated voltage● For use as a temperature limiter or monitor ● Certified according to EN 14597, optional EN 61508 (SIL2)● configurable operating / configuration lock ● Universal signal input ● 2 relay changers + analogue output● Intuitive operation: Illuminated graphic display ● Display colour change in the event of an alarm "white / red"● Safe 3-way galvanic isolation ● Wide range power supply 18..230 V AC / DCCharacteristics The temperature limiter TB225 is used for applications wherethermal processes must be monitored and the system must be switched to a safe operating state in the case of a fault. Thedevice has universal inputs for the connection of double thermocouples,Pt100 sensors, and normized signals (0/4..20mA or0/2..10V). The safety function is provided by means of the main relay with configurable threshold. An additional relay with anindependently adjustable threshold is provided for additional signalling. The TB225 also offers an analog output which can befreely defined within the measuring range of the temperature input.The resetting of the device in the operating mode as a temperature limiter can take place via the buttons on the front, the integratedgraphic display, or using an external switch or external voltage. The TB225 has safe 3-way electrical isolation between input, output,and auxiliary voltage.Brief information The connected temperature signal is evaluated and monitored. Ifthe permissible threshold is reached or an error occurs within the permissible temperature range, the TB225 switches offimmediately. The additional relay output of the TB225 enables the function of a preliminary alarm with an independent threshold.The following operating modes are possible through configuration:dsh_fam_tb225_en V2.05-03: 18 – 230 V AC/DC : < 5 VA : 250V AC in accordance withEN 60730-1: 10/2011, between input / relay output / auxiliary voltage, Degree ofcontamination 2, Overvoltage category III Rated surge voltage 4kV Conformity: CE Environmental conditions Operating temperature : -10..+55 °C storage temperature: -20..+60 °C Relative air humidity : < 95 % Condensation : not permittedApprovals TitleEN 14597: 2012 : Temperature control devices and temperature limiters for heat generatingsystemsEN 61508:2010 SIL2 : Functional security safety-related electrical / electronic / programmableelectronic systems Input Pt100 : -100.0..600.0°C Accuracy : 0,2%, ±1 DigitTemperature coefficient : 0,01%/K Thermocouple : Type J:Fe-CuNi-100..800°CType K: NiCr-Ni -150..1200°C Type N:NiCrSi-NiSi -150..1200°C Type S:Pt10RH-PT 0..1600°CReference junction compensation integrated Accuracy:: <0.3 %, ±1 digit Temperature coefficient : 0.01 %/K Analog input : 0/2..10 V DC, 0/4..20 mA0..10 V und 0..20 mA not allowed for temperature limiter Accuracy : 0,2%, ±1 DigitTemperature coefficient : 0,01%/K Display : graphic LC display with 32 x 90 pixel,with white/red background lighting Outputs Switching outputs : 2 x relayChangeover relay : < 250 V AC < 500 VA < 2 A ohmic load < 30 V DC < 60W < 2 A ohmic loadInternal main relay secured with 2A fuse!Fuse is not interchangeable!Analog output : 0/4..20 mA load ≤ 500 Ω 0/2..10 V DC load > 500 Ω electrically isolated.Output switches automatically (load-dependent) Housing : polyamide (PA) 6.6 , UL94V-0,TS35 in accordance withDIN EN 60715 Weight : approximately 180 g Connection : screw terminals 0.14..2.5 mm²with wire protection 0.14 - 2.5 mm² (AWG 26 - 14) Protection rating : IP20, BGV A31
