INTERNAL FEATURES
RELAYS
3 DPDT (form C) on board relays per module, for high, low and fail setpoints. Rated at 5 Amps
at 250 VAC, 30 VDC Resistive.
AUDIO
Individual audio alarm (with internal on/off switch
)
POWER SUPPLY
120 VAC or 240 VAC 50 to 60Hz, 10 VA. The on board transformer has dual primaries for
either 120 VAC or 240 VAC. The standard configuration is for 120 VAC, however if 240 VAC is
required a factory modification can be made.
TRANSMITTER POWER SUPPLY
The QAS-51000 has been designed to support any of QEL's line of remote transmitters as
well as many other types. The power supply for the transmitters has regulated current and the
voltage will vary from 24 VDC to 32 VDC depending on the load.
4 – 20 mA SIGNALS
QEL two and three wire transmitters all supply 4 to 20 mA linear signals.Those users who wish
to monitor signals from other equipment may do so using only signal and ground connections.
It is also possible to use QEL transmitters with local power supplies rather than that supplied
by the controller where wire savings make this worth while
FUSE
The power supply is fused on the primary. The fuse is located on the bottom of the main
circuit board.
