Output relays
The following are available:
• 6 electromechanical relays (KS1-1...KS1-1...6),
• 4 solid state relays
Each final relay is independently programmable with operating mode normally excited or de-excit-
ed (
EXCITED/DE-EXCITED LOGIC
) and non-memorised, pulse or memorized operating mode
(
NON-MEMORISED/PULSE/MEMORIZED OPERATING MODE
).
A programmable timer is available for each final relay, which sets the minimum pulse duration of the
relay itself. The parameters can be set in the menu
Set \ Relays.
Programming and configuration area available at any time, even with the relay in service, inde-
pendently for each relay.
Detailed information:
• If a final relay is set to normally de-excited, it remains in standby at input values corresponding to
no trip
• If a final relay is set to normally excited, it remains in operation when powered and at input values
corresponding to no trip
• If the relay is set to automatic reset (
Operating mode NON-MEMORIZED
), it switches to
standby when the anomalous condition of the input value ceases. A timer can be set for each final
relay to set the minimum hold time when the relay is actuated (Minimum operating time)
• If manual reset is set (
Operating mode MEMORIZED
), the final relay remains actuated until
the RESET button is pressed or the respective command is sent via software (ThySetter of comms
bus)
• If set to pulse mode (
Operating mode PULSE
), the final relay switches to standby after a pro-
grammable delay (Minimum operating time) regardless of the condition of the input values
Output relays KS1-1...KS1-6 can be assigned independently in the menu for the individual; protection
functions, as shown in the matrix described below (Tripping Matrix).

Each relay on the external DMRIS0 board (DMRIS01-1...DMRIS01-12 and DMRIS02-1...DMRIS02-12)
can be mapped to one of the default functions listed below..

Note 1 When assigning functions to the output relays, take care to avoid conflicts between different functions.
The default factory settings provide for deactivation of all output relays.
