Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The IS200WETBJ1ABA functions as a termination interface within the Mark VIe I/O architecture. While primarily a passive signal distribution board, it maintains compatibility with deterministic network communication by providing the physical contact interface for shielded I/O cabling. The board layout ensures minimal signal attenuation, supporting the integration of field sensors into Profinet or EtherNet/IP enabled I/O packs. Firmware flash compatibility is managed at the associated I/O pack level, ensuring that signals routed through the terminal board are processed according to the system's defined timing and logic requirements.

Frequently Asked Questions

Q: Is the IS200WETBJ1ABA a field-replaceable unit (FRU)?

A: Yes. The board is designed for field replacement; however, all connected field wiring must be labeled and disconnected according to the system wiring diagram before the PCB is detached from the mounting rail.

Q: Does this terminal board require external power for operation?

A: The board serves as a distribution point for 28 VDC. While it consumes minimal power for onboard diagnostic LEDs, the primary load is associated with the field devices and the connected I/O packs.

Field Installation Guidelines

• Mount the board on a standard DIN rail using the integrated mechanical clips, ensuring the PCB is level and tension-free.
• Ensure all field wiring is terminated with proper lugging to maintain contact pressure within the screw terminals, limiting resistance in analog signal paths.
• Verify that the cable shields are grounded at the designated terminal points to prevent noise coupling into the analog/digital signal circuits.
• Maintain a minimum clearance of 5 cm from high-voltage AC conduits to prevent inductive interference.
• Conduct a point-to-point continuity test from the field device to the I/O pack interface after installation to confirm correct signal routing.
