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%.
