Hydrastep 2468CB and 2468CD Manual | Relay Output Board Option |
3A.1 GENERAL DESCRIPTION
The Relay Output Board (PCB 24680504) has four relays and is mounted on top of the input board using 3 nylon spacers. Electrical connection between the two boards is via plug and socket (SK1 on the input board and PL1 on the relay output board).
A second relay output board may be mounted on top of the first on nylon spacers. Holes have been drilled on all relay output boards to receive the 3 nylon spacers. The top board is offset towards the centre of the unit improving the cable layout from the relay output boards. The nylon spacer fixing holes and mounting holes are illustrated in Figure 3a.1 on page
Each of the 4 relays can be energised by any one of up to 16 electrodes, with an individual choice of being energised when its selected electrode is in steam or is in water. Furthermore, relay RL1 can be used to monitor an electrode state or to register an ALARM condition. When set to register the ALARM state, the relay is energised in the ‘system normal’ state and

3A.2.2 MECHANICAL INSTALLATION
The output board is mounted directly on top of the input board. The input board is supplied with three nylon spacers fitted. The output board is then aligned on its Berg socket/plug interconnection (PL1/SK1) and input
When two output boards are required to be mounted on an input board, the second output board is mounted on three nylon spacers fitted on the first mounted output board.
