Fields of application
- Preparation and call-up of signal voltages UE = 0…±10 V.
- Generation of voltage ramps t = 0.05…10 s via potentiometer settings on the front side.
- By means of the DIL switch S1, the command values P3/P4 can be connected with or without ramp function.
| DIL S1._ | Ramp | |
| .1 | .2 | P3/P4 |
| 1 | 0 | ON |
| 0 | 1 | OFF |

Project planning information
The amplifier card may only be unplugged and plugged when de-energized.
The distance to aerial lines, radios and radar systems must be sufficient (>1 m).
Do not lay solenoid and signal lines near power cables.
For signal lines and solenoid conductors, we recommend using shielded cables.
The cable shield must be connected to the control cabinet extensively and as short as possible.
The valve solenoid must not be connected to free-wheeling diodes or other protection circuits.
