Four-channel GSM data logger with pulse and two-state inputs with integrated modem

TECHNICAL DATA

The data logger is designed for record from pulse input et two-state.

If the defined limits are exceeded, SMS and JSON messages can be sent over a GPRS data connection.

He's possible to define the regular sending of messages JSON to the database, the send interval is adjustable.

The recording is carried out in a non-volatile electronic memory.

The data can be transferred to a PC via USB-C.

Data logger inputs can be configured for four two-state inputs or two two-state inputs and two a pulse counter.

The device includes a traceable calibration certificate with declared metrological traceability of standards based on the requirements of EN ISO / IEC 17025.
