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 |
|
|
|
| |
|
|
|
| “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 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. |
|
|
|

| Maximum voltage = 30 V |
|
|
|
| Maximum current = 8 mA |
|
|
|
| “On” voltage: V OUT(On) < 0.8 V |
