RDL ST-RG1 Ramp Generator 0 to 10 Vdc Output

Ramp Generator - 0 to 10 Vdc Output

The ST-RG1 is a digitally generated 0 to 10 volt Ramp Generator which provides the ideal interface for audio volume control from multiple points with the ST-VCA3. Any number of Up and Down buttons may be connected to the ST-RG1. Sufficient drive is provided from the ST-RG1 to control up to six ST-VCA3s.

Features:

• VCAs may be controlled from several locations with the optional RLC2 Remote Level Control panel or RUC-4 Universal Remote.
• LED level indicator driver circuitry is included in the ST-RG1 for visual indication of relative level.

Specifications:

• Control Inputs:1 to ramp up, 1 to ramp down
• Input Logic:External closure pulls normally low input to +15 Vdc to activate UP or DOWNfunction
• Indicator Outputs:1 to drive red LED (partial to fully OFF)
• 1 to drive green LED (partial to fully ON)
• LED Output Current:0 to 3 mA (to drive low current, high intensity LEDs)
• Ramp Output:0 to 10 volts nominal, (typical < 0.1 V to > 9.8 V under ST-VCA3 load)
• Minimum Step:200 mV nominal
• Ramp Time:5 seconds nominal (fully off to fully on; or fully on to fully off)
• Power Requirement:GROUND-REFERENCED, 24 Vdc @ 40 mA
• Ambient Operating Environment:0 C to 55 C
