Specicationsfor21Vdc/dcPowerSupply
Input voltage: 10.8 to 16.0 Vdc•
Input current: Will be double the current draw of •
the output device, e.g. 100 mA typical at 12 Vdc
with a 50 mA load on the output; 140 mA max
over temperature range with a 50 mA output
load.
Output voltage: 21.4 Vdc ±0.8 Vdc•
Output Current: 50 mA max•
Ripple/Noise: 20 mV max P-to-P•
Efciency: 88% typical•
Fuses: F1=500mA (slow blow) protects the •
power source; F2=350mA (fast blow) protects
21V dc/dc Power Supply from short circuits on
the output.
I/O CONFIGURATION
Note that the base I/O, 2 DI/PI, is located on the
Processor/Main Electronics board. Also, the RTD
input and MVT (Multivariable sensor) interface are
located on the Processor/Main Electronics board.
Additional I/O circuitry is located on an optional I/O
card, which plugs in to the ControlWave Express
chassis. You can choose the minimum I/O congu-
ration of 2 DI/DO, 4 DI, 2 DO and 2 HSC/DI or an
expanded version, which additionally includes 3 AI
or 3 AI and 1 AO point.
What is the difference between a “PI” (pulse in-
put) and “HSC” (high-speed counter input)? The
HSC circuitry includes de-bounce, which is useful
with form ‘C’ relays, such as those in some pulser
devices. A PI does not include the de-bounce
circuitry and is, therefore, not recommended with
relays. Note that, in the HSC inputs, the de-bounce
can be enabled/disabled by the user and they are
shipped disabled.
We recommend that users select the 3 AI / 1 AO
conguration if use of analog I/O is anticipated in
the future because addition of the points requires a
change-out of the I/O card—due to hazardous area
certication requirements, that can be done only at
the factory.
