Reading up to 100 devices

The DL171 model is a GPRS data logger (or GSM / 3G) which has three internal 3-phase electricity meters, which can be configured also as 9 single-phase or as a combination of single-phase and three-phase meters. Like all SenNet dataloggers, the DL171 can read up to 100 devices.

Reading the devices

For data capture, the model DL171 incorporates a radio frequency module (868 MHz) as well as RS232 and RS485 ports. WiFi and GPRS connectivity are optionally available. With all these possibilities, the datalogger can communicate with almost any device regardless of the distance. Moreover, the datalogger has the option co include an USB port. It can also read utility meters using the digital inputs for pulse counting.

The model DL171 supports the same protocols as other SenNet dataloggers, that is: Modbus RTU & TCP, Mbus, KNX, Z-Wave (optional), IEC 870-5-102, DLMS / COSEM, IEC 62056-21, IEC 61017… Likewise, it supports proprietary protocols.

Internal electricity meters

The internal electricity meters allow monitoring: power, energy (active, reactive and apparent), power factor, current, voltage and frequency.

Sending the data

Like the models DL170 and DL172, the data concentrator DL171 has GPRS / GSM or 3G for data submisission. The device can send the data though the internal cellular router or through Ethernet. Furthermore, a WiFi modem can be installed to the optional USB port. Furthermore, the energy management platform All in One, can be embedded into the datalogger so the data are sent to an internal server of the client, without sending them to the cloud.
