Digital output modules with relay output provide changeover contacts at their outputs.
Current carrying capacity of the outputs
250 V AC, 12 A
Relay output
25 V DC, 12 A
Settings
Digital output modules with rotary coding switch
 Setting principle (page 9-81)
Terminal assignment 1 (TRIP)
L Signaling contact overload tripping
Signaling contact short-time delayed short-circuit
S
tripping
I Signaling contact instantaneous short-circuit tripping
G Signaling contact ground-fault tripping
G ALARM Signaling contact ground-fault alarm
N Signaling contact neutral conductor tripping
Delay time setting
TRIP 0 - 2 sec.
ALARM 0 - 2 sec.
The delay time setting determines how long a signal of the trip unit must be present until the corresponding LED lights up and the signal is
set at the corresponding output.
Output assignment 2 (ALARM)
Signaling contact leading signal overload tripping
PRE TRIP
(delay time 0 sec.)
TU ERR Signaling contact ETU error
LD SHED Signaling contact load shedding (delay time 0 sec.)
Signaling contact load restore
LD REST
TEMP Signaling contact temperature alarm
I UNBAL Signaling contact phase unbalance current
Configurable digital output modules
Configurable digital output modules can be adjusted via:
- the test socket of the trip unit with the BDA
- the PROFIBUS-DP / MODBUS.
