Omega Engineering CCT-55-I manual Overview, Types of Pulses

SIGNAL OUTPUT module MS-55

OVERVIEW

This module contains all the components for the frequency generator, and the trimmer for the Span coarse frequency, The jumpers and solder pads to select the output range frequency and solder pad to select the pulse width.

Both models are delivered as a standard version, with the frequency output adjusted from 0 to 4 KHz., unless specified otherwise.

The frequency range can be set in pulses per second (12 different ranges, see table 2) or in pulses per hour (13 different ranges, see table 3), using the jumpers and solder pads located on the MS-55 module, see figure 5.

TYPES OF PULSES

The signal conditioner provides two different types of output pulses.

Pulses in Current: 100 mA. (24 Vdc external power supply), terminals 9 - 10

Pulses in Voltage: 24 Vdc. @ 20 mA maximum, terminals 11 - 12

Do not use both outputs simultaneously. Only one selection can be made.

The side label shows which one is selected.
