Product Description

dynaparApplication for Industry

The model PM28S provides six types of input functions in one easy-to-use, two-channel isolated product.

DESCRIPTION:

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 typically drive up to six loads. 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
