The OPCARD-8 has been developed for use with the Haes conventional control panels to provide up to 16 common or zonal outputs. The card consists of 8 x switched -ve outputs and 8 x volt free changeover relays. A permanent 28v supply is required which can be taken from the 28v output on the main circuit board of the control panel. The card also provides a 28v output which can be utilised if driving additional relays from the switched -ve outputs.
Up to 4 output cards can be linked together to provide up to 32 common or zonal outputs.
The outputs have several configuration options including common or zonal operation. The configuration options are set by a simple DIL switch selection.
