5.5 D90/D91/D92/D93/D99 Distribution Unit
The unit has 4 screw holes for mounting, and should be placed as
near the Control Unit as practicable. It can also be mounted inside the
console.
For AC mains connection an AC adapter rated at 24VDC 1,5A must
be connected between the mains source and the Distribution Unit
(not standard scope of supply).
For electrical connections see Wiring Diagrams.
Depending on type of Distribution Unit, the solid state relays are
capable of operating solenoids for high and low DC or AC. Analogue
voltage or current signal is also available for steering gears that
requires analogue input signals and for reversible motors.
The relation between type of Distribution Unit and control voltage is
as follows:
D90: Single relay output for low DC (19-40V), 3A
D91: Single relay output for high DC (110V), 1A
D92: Single relay output for AC (110-220V/50-60Hz), 1A
D93: Dual analogue voltage/current output (±10V and 4-20mA)
D99: Output to control reversing motor (20A max.)
