To alert a user when process parameter exceeds the limits is an important function of a data logger. The IM2000 series normally provides alarm relay outputs and the user can have common relay for all channels or can have individual relays for each channel. These channels can be grouped as well. Apart from the user, the other concerned persons in the plant should know that there is an alarm. SMS Data Logger / GPRS Data Logger generate a text alarm message as soon as the alarm condition is observed. SMS technology can be used to send periodical process updates as well. It can be used to send data to remote PC connected to GSM Modem. Information can be transferred with the help of GPRS technology as well. Thus the field conditions can be monitored any where in the world at any given point of time.
