FAQ

• Q: Can TDBSH2A supply 48 VDC or 125 VDC?
  A: No, the H2A variant is limited to 24 VDC. Use H4A for 48 VDC or H6A for 125 VDC applications.
• Q: What I/O pack mates with this board?
  A: It is designed for use with IS220PDIOH1A/B discrete I/O packs via DC-37 pin connection.
• Q: Is it suitable for TMR?
  A: No, the IS200TDBSH2A is simplex only. For TMR discrete I/O, use TDBT or TDBU terminal boards.

Selection Tips

• Specify IS200TDBSH2A for simplex Mark VIe discrete input applications requiring 24 VDC wetting voltage.
• Order compatible option boards (WROB/WROF/WROG) for enhanced protection and power distribution.
