müller MR 28.10 pro

Overview

Digital multifunctional relay
1 channel [CO]
20 functions
Time range 0,1s up to 999h
Minimum interval 0,1s
Free adjustable time range
*Power Fail Security (adjustable)
*Security Request after Power Fail (adjustable)
Elapsed time and pulse counter
Security by PIN-Code

External input

*An interruption of the devices power supply turns off the relay. The state of the relay and the already elapsed time are saved and loaded on resumption of power supply. The saved state prior and the elapsed time to the power failure will be recovered after resumption of power supply. This process can be protected by a securtity request.

The device fits for the particular use of the following tasks: switching of a relay after an in front defined time interval and function (switching characteristics are adjustable)
Any other uses than those just described are not permissible and are not for the intended purpose.
