MODEL 223 FREQUENCY TO VOLTAGE CONVERTER
Features
Description
The Model 223 is a two channel F/V module that plugs
into Encore's
19" GPSC instrumentation rack, which accommodates up to eight
modules (16 channels).
An AC power supply is built into the rack,
and provides
the required unregulated DC voltages to operate the modules.
