Datalogger for 3 Voltage Inputs 0-10V and 1 Two-state Input
Datalogger is designed to record 3 voltage inputs and 1 binary input. The recording is performed in non-volatile electronic memory. The data can be transferred to a PC via USB-C. In case of exceeded set limits alarms are indicated by LED, LCD, and acoustically by built-in beeper. The recorder includes a Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Datalogger with 3 inputs 0 – 10 V and 1 binary input
This model is used to measure up to three voltage inputs 0 – 10 V DC while allowing one binary input to be monitored. The voltage inputs are not galvanically separated from one another. This means that the negative terminals («-«) are connected to each other. These facts must be taken into consideration when designing the device into the circuit. Incorrect connections may cause degradation of the measured values. Binary input serves to monitor voltage signals or signals coming from a voltage-free contact.
Connection Mode: For the procedure for connecting wires to the connecting block refer to Annex 4.
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 input can capture connected/disconnected voltage status. Input signals are connected to a connecting block. The device’s ingress protection is IP 20. Due to its low ingress protection, the device is not suitable for use in dusty rooms or rooms exposed to water ingress. The maximum length of the input wires should not exceed 30 m. It is recommended to use shielded cables. The battery in the device cannot be charged.
