2 ASPECT SIGNALLING |
|||
| SIGNALLING | |||
| IRDASC-1 This operates 2 aspect LED signals wired common to negative. | |||
| IRDASC-2 This operates 2 aspect signals via a relay output for bulb or LED signals. The LED signals may be either common negative, common positive or 2 wire signals such as Patronics. | |||
| IRDASC-3
Operates signals in same way as IRDASC-2. There is an additional relay contact which opens when the signal is at red. Its purpose is to stop trains running through a red signal. The isolation section
is positioned in front of the signal. |
|||
| SA7-SB This unit combines signal operation with gradual adjustable slowing and acceleration. Like the other units each SA7-SB forms a signalling block section. | |||
| SA8-SB This operates a station stop block section. There is gradual acceleration and braking of the train. | |||
| SA5-SB This unit operates the signals and points of a loop as a block section with gradual braking and acceleration. | |||
| SA6-B This unit is for where a series of out of sight storage loops are used as part of a block system. | |||
| The IRDASC units can be used with either conventional DC control or with DCC control. The SA units can only be used with conventional control. | |||
| Train Direction Detector This indicates in which direction a train is travelling. Useful for single lines running trains in both directions | |||
