If only a GSM connection is available for tele-monitoring installatikons in far afiled places and power supply may be an issue, the Delta 300 is the best choice. Minimum power consumption and the possibility to connect an accumulator (even rechargeable through the device by, e.g. using a solar panel) ensure months of unattended operating time.
The Delta 300 is designed for distributed installatins in which some operating conditions have to be monitored. It is available in different housings and with different power supply variants ranging from 12/24 V DC via standby accumulator to a simple battery.
The Delta 300 monitors 4 digital inputs (as well usable as pulse counters), 2 analog inputs and 2 temperature measuremetn inputs. Alarm conditions can be defined for changes occurring to input signals. Resultung alarms are sent by SMS. Furthermore 2 switching outputs are provided. By logical combinations of input signals, limit values, switching commands and alarms potential failure situations can simply be monitored and handled.
Alternatively to phone number addressing SMS can be routed to e-mail accounts. Just enter the phone number of the SMS-e-mail-gateway and recipient dring device configuration.
