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.
