3.6.2.8 Digital output (Transistor)
Control signal terminals 8 and 11 (
gure 84) are configured as analog
outputs (AO) by default. Parameters P2-11 and P2-13 can be used to
configure them as digital outputs (DO) instead.
The Transistor outputs DO1 (terminal 8) and DO2 (terminal 11) switch the
device-internal control voltage (+24 V) as a digital signal.
The maximum permitted load current is 20 mA.

3.6.2.9 Relay output
DA1 variable frequency drives feature two relays with dry contacts.
Relay K1:
control signal terminals 14 (change-over), 15 (closer) and 16 (opener)
Default setting: 1 = Standby/error (Error)
Relay K2:
control signal terminals 17 and 18 (closer)
Default setting: 0 = Drive running (RUN)
The relay function can be configured using parameters P2-15 and P2-18.
The electrical connection specifications for control signal terminals or relay
contacts are:
•
250 V AC, maximum 6 A
•
30 V DC, maximum 5 A
￫
Control signal terminals 7 and 9 are the common 0 V reference
potential for all analog and digital signals.
