Product Description
 DC-TDOD51 HONEYWELL Digital Output Module


Product Description


 The Honeywell DC‑TDOD51 is a 24 V DC digital output I/O Termination Assembly (IOTA) module in Honeywell’s Series C Mark II family, used

in Experion PKS / C300 control systems.Mounted via an IOTA board, which handles field wiring and power distribution.

Provides 32 digital output channels.Outputs are current sourcing (“Source” type) 24 V DC.

Frequently Asked Questions


Q1: What is the difference between DC‑TDOD51 and DC‑TDOD61?

  • The DC‑TDOD51 is the non‑redundant (single) IOTA module.

  • The DC‑TDOD61 is the redundant version that allows two I/O modules to be used for fault tolerance. 

Q2: What happens if a field short circuit occurs on one of the channels?

  • The module’s protection circuitry detects over-current on that channel, shuts it down, and flags a “Soft Failure.” Only that channel is affected; the others remain operational. 

Q3: Can I power the outputs from an external 24 V supply?

  • Yes. The Series C I/O spec allows for “field power excitation” via external 24 V, in which case the outputs can be galvanically isolated from the I/O system power. 

Q4: What is the “FAILOPT” behavior?

  • FAILOPT (fail‑option) lets you configure what each channel does in a failure: you can make an output hold its last value or shed to a safe value (user-defined). 

  • Note: this is more commonly documented for the IOM modules, not strictly the IOTA, but behavior is governed by system I/O configuration.
