Professional FAQ & Selection Guide

• Q: How are inputs and relays connected on this terminal board?
• A: Input circuits utilize TB2 (lower terminals), while the relay section connects via TB1 (upper terminals) for clear signal separation.
• Q: Can I use this board without a PDIO I/O pack?
• A: No, a single PDIO I/O pack is necessary for proper operation; the board relies on the pack for controller-level communication.
• Q: Does the IS200TDBTH6A require hardware jumper configuration?
• A: No, the main terminal board has no hardware jumpers; only the optional relay boards require jumper settings for dry contact activation.
• Q: What is the benefit of the conformal coating on this model?
• A: It provides a protective barrier against moisture, dust, and corrosive gases common in harsh industrial turbine environments.
• Q: Selection Advice: What if my field voltage changes?
• A: Ensure the input wetting voltage (24/48/125V) is set to match your field sensors; the board is designed to handle these ranges natively through signal conditioning.
