U0843M - GSM temperature data logger for two external probes and two two-state inputs with modem
This model can measure up to two temperature values, which are sensed by outdoor Pt1000/0 series probes. In addition, it is provided with two binary inputs for monitoring voltage-signal changes or changes of a signal coming from a voltage-free contact. The binary input changes are registered immediately, irrespectively of the recording interval setting. To safe record the input status, the signal must be present for at least 1 s. Binary inputs of this device are not able to capture connected/disconnected voltage status. Input signals are connected to a connecting block. The response to a temperature jump depends on the probe design. As a rule, this device is few times faster than the inner-sensor model. The maximum length of the probe line wire should not exceed 15 m; the maximum length of the binary-input cable should not exceed 30 m. It is recommended to use shielded cables. The device’s ingress protection is IP 20. Due to low ingress protection the device is not suitable for using in dusty rooms or rooms exposed to water ingress.
