Channel-to-Channel Isolation and Bus Signal Integrity
To secure communication integrity along the high-speed local backplane, this module matches the characteristic impedance of the differential transmission line. By absorbing residual energy at the terminal node, the device suppresses signal reflections and high-frequency noise. This passive design minimizes wave distortion and differential signal degradation without introducing active thermal drift or requiring independent channel-to-channel isolation circuits.
Frequently Asked Questions
Q: Where exactly must the 1B30023H01 be installed on the Ovation bus?
A: Install this module exclusively into the physical terminal slot at the final end of an I/O bus segment. Placing the terminator at any other node will cause impedance mismatches and communication faults.
Q: Does this terminator module require a separate external power connection?
A: No. The module acts as a passive network, consisting of high-tolerance matching resistors. It draws no operating current from the backplane and does not require an external power supply.
Q: How does this module handle backplane voltage tolerances?
A: The design safely accommodates standard Ovation backplane signaling ranges, including 5 VDC logic networks and 24 VDC industrial control signals.
Field Installation Guidelines
- Insert the terminator module into the dedicated end slot of the I/O backplane, verifying that all physical pins mate evenly prior to locking.
- Confirm that only one terminator is installed per physical end-of-line segment to avoid over-terminating the transmission path.
- Keep communication cables separated from primary AC power distribution lines to prevent inductive noise injection into the terminated bus.
- Ground the rack housing and the backplane assembly to a central instrument ground bar to maintain an effective noise shield.
