The model PM28S provides six types of input functions in one easy-to-
use, two-channel isolated product.
As an amplifier, it accepts differential line driver, single-ended, and
magnetic signals, converting them to single-ended signals for use with
counters and indicators. This unit is isolated from input to output, and
allows input signals to travel long distances without degradation. The
isolation provides higher noise immunity for the total system.
The input termination is programmable to match most encoders,
pickups and other input devices, including many low level flow meters.
The PM28S also provides a power source for encoders, pickups and
other input devices. Its special MOSFET output will drive up to six
Dynapar MAX or MAXjr products.
The two channels operate independently, so any combination of inputs
can be used. All field connections are made through a terminal strip
which accepts number 22 through 12 AWG.
■ Two independent channels
■ Selectable inputs – differential inputs, 12V inputs, 5V inputs, TTL
■ Transducer supply
■ Selectable line termination
■ Hysteresis on inputs
■ Noise filtering
■ Isolated MOSFET line driver outputs – allows user to drive 6 MAX or
■ Selectable 115/230 VAC operation
PM28S replaces PM21, PM25 and 101UA
inputs, magnetic inputs, 50 mv inputs for low level flowmeters
