Continuum I/O System Reference
43
The DI-8, Continuum’s digital input module, is used for cost-effective sensing of multiple
dry digital inputs in applications such as equipment status monitoring or alarm point
monitoring. The DI-8 has eight digital inputs
each can be software configured to accept
a digital (contact closure or 0-5 volt input) or counter signal. Counter frequency is 10Hz
on all eight inputs. In addition, high speed counting up to 10KHz max. is available (via a
DIP switch) on Channels 1 and 2 for high-speed metering and industrial applications.
40V transient suppressors on all eight inputs protect against high voltage short duration
transients events. The DI-8 is designed to accept dry contact inputs or 0-5 volts and can
withstand up to 24 VAC/DC continuous voltage on four channels.
FEATURES
•
Allows interface to relay contact closures or 0-5v
digital signals.
•
Allows high speed counting on channels 1 and 2.
•
Input protection allows accidental wiring of
24VAC to inputs.
