OPCARD-8 has been deisgned to provide up to 16 common or zonal outputs.The card consists of 8 x switched -ve outputs and 8 x volt free change over 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 sw -ve outputs. Up to 4 output cards can be fitted to the control panel and linked together to provide up to 32 common or zonal outputs. The outputs have several configuration options including common or zonal operation. The configurations are set up by a simple DIL switch selection which is described in this document.
