2.3.1 HARDWARE ARCHITECTURE
A GARD 8000 System always includes
Power supply, single or redundant with alarm relays and rear terminal block
Controller module, single or redundant, with rear System I/O’s
Display With TPS module with front System I/O’s
Base Teleprotection comms port (RS449, X.21, V.35) located on the rear System I/O board in
the 6U chassis or on the power supply rear plate in the 3U chassis
In addition, the System is equipped with order specific communication interfaces, inputs, outputs and
functional modules.
The chassis is equipped with a motherboard ‘midplane’ and modules plug in from both front and rear.
The following modules occupy a slot in front only:
Main HMI and Logic Processor Module (fixed location in the chassis)
Display and base digital teleprotection module (fixed location in the chassis)
Additional digital teleprotection module. Note that the Base System always includes one 32
function TPS but that additional teleprotection systems can be added as separate functional
modules.
The following Modules occupy a slot in rear only:
All digital communication interfaces with 6 inputs or 6 outputs:
o T1/E1
o RS 449/X.21/V.35 56 -768 kbps
Note that one RS 449 communications interface is always included on the rear
System I/O module
o G.703, co-directional, 64 kbps
o C37.94 fiber
o Single-mode fiber; up to about 80 km
Inputs and/or Outputs. The inputs and outputs are combined in blocks of six. Each input-output
combination occupies one rear slot. The following options are available:
o 12 opto-isolated inputs
o 6 opto-isolated inputs
o 6 inputs, 6 solid state outputs
o 6 inputs, 6 relay outputs
o 12 solid state outputs
o 6 sold state outputs
o 6 solid state outputs, 6 relay outputs
o 12 relay outputs
o 6 relay outputs
Analog 2W/4W teleprotection system with terminals
System I/O (fixed location in the chassis)
