Each DI-8B45 module isolates and conditions a frequency input signal and provides an analog voltage output. The frequency input signal can be either a TTL level or zero crossing with as little as ±100m V 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 block diagram (p 2). A 5V excitation is available for use with magnetic pick-up or contact closure type sensors. The excitation is available on the EXC terminal with return on the - terminal. A special input circuit on the DI-8B45 modules provides protection against accidental connection of power-line voltages up to 240VAC. Clamp circuits on the I/O and power...
