The Edison model 1616 monitor is designed to provide simultaneous, continuous surveillance of up to 16 addressable RTDs connected on a common 4-wire buss. RTD relays are internal to the main monitor unit. The entire system is self-contained in that it supplies all field RTD transmitters with their power requirements for distances in excess of 1000 ft. The RTD is connected to an RTD transmitter where the temperature characteristics are converted to a digital protocol for the monitor. The 1616 monitor accepts industrial standard RTD inputs for Nickel, Platinum, and Copper characteristics. Installations can include single or fully configured 16 RTD transmitters. There is no calibration required for the monitor.

RTDs are electronically scanned and their temperature is compared to the user's pre-selected two trip points. When the RTD temperature exceeds the pre-selected menu temperature, a system alarm relay will trip and then the alarm detail can be viewed. The printer will print the details of the alarm, if utilized. Should the temperature continue to change in the same direction, a second "alarm relay" will trip for that specific RTD. Different combinations of configuration for each point is available for alarm on rising or alarm on falling. Each point allows the user to insert a memo field that will be displayed when the unit alarms. In coming alarms can be viewed in detail at the display and/or printed out to a printer for evaluation.

A system failsafe fault relay changes state in the event of any type of fault. This fault will be displayed at the display and will be printed to the printer.

Programming is implemented by utilizing a standard PC keyboard, temporarily connected to the front bezel. The user programs preset temperature values into the monitor as well as RTD specific messages.
