BCD to Decimal Decoder
Tiny circuit made to fit neatly inside
equipment or against a rear panel.
Supply power and BCD input on one
end and decimal line corresponding to
the BCD code goes high on the other
end.  12 or 5 volts can be used.
BNC Splitter/Combiner
BNC Switcher
2-input Holding to Pulse
Interface
4-input Optoisolated Interface
High Temperature Alarm
4-input Optoisolated Relay
Interface
4 BNC connectors all resistively joined
together.  Good for splitting or
combining low frequency signals.
Resistor values are determined by
input and output impedance needs.
Relay selects which BNC input is
connected to the BNC output when
5 volt control on pin jack is on or off.
Perfect for switching signals at the
transmitter site via remote control.
When the input is pulled to ground,
from a set of holding relay contacts, for
example, the output relay contacts
close for 2 seconds, then relax.
Works on input power of 8 to 28 volts
and has 15-pin D-sub connector
interface to the outside world.
4 optoisolated channels designed to
maintain galvanic isolation and logic
level shifting between pieces of
equipment at the studio or transmitter
site. Different input and output
voltages can be accomodated. Please
let us know your requirements.
Uses a bandgap semiconductor sensor
to provide temperature control. Relay
pulls in at 40 C (104 F) and these dry
contacts are available on the 9-pin
D-sub connector.  Also, 2 volts DC is
output as a temperature tally for use
with an analog metering system. LEDs
indicate power and high temp. trip point.
Optoisolated input and dry relay
contacts for the output with LED
indicators to show which relay is
energized.  External power is from a
power cube via the coaxial power
connector. Input for each channel is a
pin jack and output is routed to pins on
the 9-pin D-sub connector.
