1.2 Options

The PULSAmatic actuator is configured at the factory for a variety of options, both singly and in

various combinations. The appropriate wiring diagrams external to the circuit board are included

with each pump shipment.

1.3 Input Signals

Standard signals are:

1-5 mA DC @ 2000 ohm Impedance

4-20 mA DC @ 470 ohm Impedance

10-50 mA DC @ 180 ohm Impedance

0-10 V DC @ Greater than 270,000 ohm Impedance

Slide wire (Remote, 1000-ohm manual control potentiometer, user-supplied).

Actions

Direct Acting- minimum and maximum input signal levels correspond directly to minimum and

maximum stroke settings respectively. For example, a 4-20 mA signal ranges stroke from zero at

4mA to full at 20 mA. This is the standard mode of action.

Reverse Acting- Signal response is inverted relative to direct acting. For example, a 4-20 mA

signal ranges stroke from full at 4 mA to zero at 20 mA. This is an optional mode of action.
