SensorLex® 8BIsolated IsolatedAnalog AnalogSignal SignalConditioning ConditioningProducts Products 8B45 Frequency Input Modules Description 8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 8B45 module isolates and conditions a frequency input signal and provides an analog voltage output (Figure 1). The fre uency input signal can be either a TTL level or ero crossing with as little as ± 100mV amplitude. Input circuitry for each signal type has built in hysteresis to prevent spurious noise from corrupting the module output. TTL signals are applied to the + and – terminals while zero crossing signals are applied to the +EXC and – terminals. Reference the bloc diagram below. A excitation is available for use with magnetic pic up or contact closure type sensors. The excitation is available on the terminal with return on the – terminal. A special input circuit on the 8B45 module provides protection against accidental connection of power-line voltages up to 240VAC. Clamp circuits on the I/O and power terminals protect against harmful transients.
