Short Form Function 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
3-4.
“OFF” voltage: 0 V < Vin < 1 V.
“ON” voltage: 2.5 V < Vin < 10 V, 5 V typically with current
consumption 2.5 mA.
2 AOK Amplifier OK When the amplifier is 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.
See Figure
3-4.
Maximum voltage = 30 V
Maximum current = 8 mA
