6.2 INPUT CIRCUIT FOR THE MODEL 414B

The Model 414B will accept basic squarewave, pulse or open collector output

signals, but is not able to read mV signals from coils, nor two wire proximity

switch outputs. The Model 414B has limited input filtering and signal levels must

switch between the levels specified below.

For open collector outputs, an internal 10K resistor will act as a load. However,

the user must still ensure that the resulting signal will switch about the specified

levels.

General Specification

Signal Types: Squarewave, Pulse or Open Collector.

Signal Level: The "low" signal level must be < 1.5Volts.

The "high" signal level must be > 3.0Volts and must not

exceed 30 Volts.

The input circuit for the Model 414B and installation examples are shown on the

following pages.
