Description
1
EN+
Enable +
Positive voltage input of the “Amplifier Enable” function.
To enable operation of the amplifier, the optocoupler
must be energized by applying voltage between this pin
(+) and pin J1/22 (-).
The optocoupler is isolated from the amplifier. See Figure
The optocoupler is isolated from the amplifier. See Figure
3-4.
“OFF” voltage: 0 V < Vin < 1 V.
“ON” voltage: 2.5 V < Vin < 10 V, 5 V typically with
“OFF” voltage: 0 V < Vin < 1 V.
“ON” voltage: 2.5 V < Vin < 10 V, 5 V typically with
current consumption 2.5 mA.

AOK
Amplifier OK
When the amplifier under normal operating conditions,
this output is in the “active low“ state. When a failure
occurs, this output is changed to the “open” state.
The optocoupler is an isolated, open collector NPN type.
