Simplest setup to monitor and log 2 thermocouples?

[Philip]

I am quoting for a job that requires monitoring of two temperatures (thermocouples) a couple of pressure switches and has two output alarms. The control panel will be in an un-manned site and user needs to know if a temperature alarm has been tripped and what the maximum/minimum value reached has been (eg value has to be logged and displayed on screen). I would like to use the MFD display plus controller. What is the simplest configuration that will support 2 thermocouples, 2 digital inputs and 2 digital outputs.

Hello Philip,

for thermocouples-input you can use:

- MFD-80-B          (Display with buttons)
- MFD-CP8-ME     (CPU-Module without network)
- MFD-TP12-NI-A (In-/Output Module for thermocouples and digital in/out)

For showing the max and the min value on display is not the problem, if you not need the timestamp from the systemclock.

Jan,

Thanks for your speedy reply.

That looks straight relatively straight forward. However I would like to log the time the first alarm is triggered and I presumed because the MFD-CP8-ME has a 7 day time clock I could log the time the alarm tripped and display this on the MFD-80-B. It sounds from your reply that there might be a problem doing this,or is it just a matter of reading the system clock and writing to memory.

Hello Phillip,

You can use the intere watch for automatic day/week/year-timers, but you have no other access on the current date and the time. You don't store it in markers. You can read ang write the date and time on display, but this it´s all.
