5.5.3 ZP3AB-OP24 Transistor Output Board
This is a programmable output board with 24 separate outputs, designed to drive low-power
functions, such as LED's or control relays. This board is suitable for driving remote mimic
panels. The outputs are open-collector transistor outputs, which switch negative (0 volts)
when activated. The opposite side of the output load (LED, etc) must be connected to a
common positive (+24 volts) from the same power supply source as the board.
Each output is allocated a unique address, and programmed to operate from selected inputs
using the I/O-mapping function built into the panel. The ZP3AB-OP24 board connects to the
ZP3panel control bus. If allocated to the UserBus section, up to 768 addresses are
available. These outputs are freely programmable. If allocated to the SystemBus section, a
further 256 addresses are available, which have pre-programmed functions.
Each board is fitted with a dipswitch, which is set to an address between 000and 255. This
determines the address of each output, as specified in the "Software Configuration" Section.
Each output can drive a maximum circuit load of 50 milli-Amperes. If outputs are used to
switch inductive loads, they should be protected with a flyback diode.
The load is provided from the 24 vdc supply connected to the power input terminals. If
connected to the ZP3 panel auxiliary power supply terminals, then this load will be supplied
from the built-in ZP3 power supply. If connected to an external 24 vdc power supply, then
this will supply the load. If externally supplied, do not common the power supplies.
