I/O Density Scaling and Backplane Communication
The 1734-TOP3 terminal base allows I/O density scaling by providing multiple field termination points within a compact footprint. Its screw-clamp design ensures stable electrical contact under vibration. The unit interfaces directly with PointBus backplane networks, preserving deterministic communication and supporting modular expansion across Point I/O 1734 modules.
Frequently Asked Questions (FAQ)
Q: What is the maximum current each terminal can handle?
A: Each screw-clamp terminal supports up to 8 A under rated voltage conditions.
Q: Can the 1734-TOP3 be used with both DC and AC field power?
A: Yes, it supports up to 28.8 V DC or 120–240 V AC on the field power bus.
Q: How should wire sizes be selected for connection?
A: Conductors from 22 to 14 AWG (0.25 to 2.5 mm²) are compatible with the screw-clamp terminals.
Q: What environmental conditions are acceptable for installation?
A: The unit is designed for industrial environments without corrosive gases and operates between -20 and 55 deg C.
Field Installation Guidelines
-
Secure the 1734-TOP3 on a standard DIN rail compatible with Point I/O modules.
-
Route field wiring separately from high-current power lines to minimize interference.
-
Use only copper conductors within specified wire sizes for screw-clamp terminations.
-
Ensure the DIN rail lock is fully engaged to prevent mechanical displacement.
-
Verify proper mechanical keying between terminal base and I/O modules.
-
Maintain clearance around the unit for safe installation and removal of connected modules.
-
Inspect terminals periodically to confirm torque and connection integrity in vibration-prone environments.
