3.4.13 Slow Pulse Input Isolated Module

A schematic representation of the field wiring connections to the input circuit of the Slow Pulse Input
Isolated module is shown in Figure 3-19.

NOTE:

The Slow Pulse Input isolated module is designed to operate only with devices having

their own power source, such as “wet” relay contacts or two-state devices providing an output
voltage. The module is inoperative with non-powered devices.

The Slow Pulse Input Isolated (SPI) module operates when a field device provides a voltage across
terminals B and C of the module. The voltage sets up a flow of current sensed by the module, which
signals the ROC electronics that the field device is active. When the field device no longer provides a
voltage, current stops flowing and the SPI module signals the ROC electronics that the device is
inactive. The ROC counts the number of times the current starts flowing, and stores the count. The ROC
checks for the input transition every 50 milliseconds.

A 10-ohms scaling resistor (R1) is supplied by the factory, which accommodates an external voltage
(V

o

) of 11 to 30 volts dc. However, it is desirable to optimize the value of R1 to reduce the current drain

from the source or reduce the heat generated in the module due to high source voltage. The formula for
determining the value of R1 displays in Figure 3-19. For optimum efficiency, R1 should be scaled for a
loop current (I) of 3 milliamps.
