AEMC Instruments DL-1081 Datasheet & Stock

AEMC DL-1081 Offers

The 8-Channel Data Logger Model DL-1081 (with display) is a versatile, powerful and cost effective data logger handling analog, digital and other types of variables with high resolution and speed. It offers high performance and is easy to configure and operate.

The Model DL-1081 has 8 configurable analog inputs that can measure thermocouples, Pt100, Pt1000, DC voltage and DC current signals. It is equipped with 2 relay outputs and 8 digital ports that are individually configurable as inputs or outputs.

Up to 128 math channels can be used to perform operations on the measured values. Up to 32 alarm events can be detected, allowing output activations, e-mails and SNMP trap sending.

The RS485 interface can operate as a Modbus RTU master or slave. As a master, it can read and log up to 64 external channels. A 10/100Mbps Ethernet interface allows access through a browser (HTTP), FTP (client and server), e-mails sending (SMTP), SNMP and Modbus TCP.

The Model DL-1081 has a mini USB interface for connecting to a computer for configuration, monitoring and data download and another USB port for plugging in a flash drive for data retrieval. The 512k internal basic memory is used to store data and can be greatly expanded with an SD card up to 16GB.

The Model DL-1081 incorporates a color display that can be attached or remotely installed for local indication or configuration. A user friendly configuration software program is included and can be accessed by Ethernet, USB or RS485 and also provides means for online monitoring, logged data downloading, printing and exporting to spread sheets and other formats.
