Description
The relay operates with all the PTC resistors according to DIN 44081 as far as the sums cold resistance in series 1500 Ω not exceed. The device operates according to the quiescent current principle, which means that the measurement circuit is open. The maximum sensor voltage is 7.6 V. through the transformer according to VDE 0551 the circuit is galvanically isolated from the mains. At a small sensor resistance is the output relay. The rated cut-off temperature sensor resistance high-resistance), NAT is reached (the output relay drops out. The response value of the device is approx. 3K with a tolerance of approx. ±8°C. The rear case value (hysteresis) is response value -10%.
