Data logger is designed to record from four binary inputs or from two pulses and two binary inputs. The recording is performed in non-volatile electronic memory. The data can be transferred to a PC via USB-C. Datalogger inputs can be set up for four binary inputs or two binary inputs and two pulse counters.

In case of exceeded set limits alarms are indicated by LED, LCD, and acoustically by built-in beeper. The device includes a Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.

Two-channel binary-input counter

This model includes four inputs. Two of them can function as counters, and all four inputs can function as binary inputs. Both counter and binary inputs serve to monitor voltage signals or signals 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 can capture connected/disconnected voltage status. The counter states are recorded according to the set Record interval. Input signals are connected to a connecting block.

Connection Mode: For the procedure for connecting wires to the connecting block refer to Annex 4.

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.

Optional input configurations:

• 2 x counter + 2 x binary input
• 1 x counter + 3 x binary input
• 4 x binary input
