According to the Law on Waste, electro coming from households free of charge and can give any amount to up to that end point of collection, as well as to store the occasion of the purchase of new equipment (in accordance with the principle of old-for-new, regardless of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the environment and human health. Purpose Temperature transducer AT-1I is designed for temperature measurement by means of an external temperature sensor and converting measured value to unified analog output current signal in the range of 4÷20 mA. Features The AT-1I module continuously converts the resistance of an external temperature sensor to a DC output signal in the range 4÷20 mA. As a result of the transformation, a current proportional to the temperature of the environment in which the temperature sensor is located appears at the output. The module works with a resistance temperature sensor type KTY81-210 (or equivalent). Dedicated temperature probes manufactured by F&F: RT probe or RT2 probe. Probes available separately. - 1 - The signal output of the module is protected by an interference filter, which eliminates mains interference affecting the accuracy of the transmitted signal. The protection allows the use of signal cables with a length of up to 300 m. Auxiliary calculation formulas Based on the linear function y= ax+b, we calculate from the formulas: [1] Iw = [0,106667 × Tm + 9,334] ±0,5%, where: [2] Tm = [9,375 × Iw -87,5] ±0,5%, where: Iw output current [mA] Tm sensor environment temperature [°C] 4÷20 mA signal output current range -50÷100°C temperature sensor measuring range ±0,5% conversion error - 2 - Mounting Recommended use of interference and surge filters (e.g. OP-230) from the F&F range. Recommended use of UTP (twisted pair) signal cables to connect the module to another device. If shielded cables are used, ground the screens on one side only, as close to the device as possible. Do not lay signal cables in parallel in close proximity to high and medium voltage lines. Do not install the module in close proximity to high-power electrical consumers, electroma-gnetic measuring instruments, phase-controlled power devices or other devices that may introduce interference. 1.Switch off the power supply to the switchboard. 2.Mount the module on the DIN rail in the distribution box. 3.Connect the probe to terminals 10-12 (polarity optional). 4.Connect signal output 1-3 to the power supply and the analogue current input (AI) of the consumer unit (polarity independent). - 3 - The maximum length of the UTP cable must not exceed 300 m. Due to the differences between the internal resistances (RAI) of the analogue current inputs of the devices that can be used with the AT-1I module, it is necessary to supply the module with an appropriate V+ voltage. The minimum voltage value can be calculated from the formula. RAI internal resistance of the receiving equipment input.
