Product Highlights
DI-8B modules are an optimal solution for monitoring real-world
process signals and providing high level signals to a
data acquisition system. 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 ±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.
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
terminals protect against harmful transients.
Isolation is provided by optical coupling to suppress
transmission of common mode spikes or surges. The module
is powered from +5VDC, ±5%.
The modules are designed for installation in Class I,
Division 2 hazardous locations and have a high level of
immunity to environmental noise.
