Power
Power supply to the WESDAC/WESTERM peripheral pairings is through the
WESTERM boards.
If you have the D20 horizontal slot chassis for a VME or non-VME installation, then
power supply to the I/O Peripherals
can
be run through the D.20 Link. This is also
possible for a D20 two-node implementation of this chassis assembly. If you have
the D200 vertical slot chassis for multi-node, then you
cannot
run the power supply
to the I/O Peripherals through the D.20 Link; you require the D.20 DC Interface
module: See “D.20 Interface Modules: connect for power using D.20 Link”, page 61
In RTU systems using more that five peripherals, an external power supply is
required and this supply is wired directly onto the WESTERM board. Typical power
consumption for D20 I/O peripherals is as follows:
D20A
20 – 60 VDC, 8 W typical
D20C
20 – 60 VDC, 5 W typical
D20K
20 – 60 VDC, 4 W typical, 11 W
with all relays energized
D20S
20 – 60 VDC, 3 W typical
