Honeywell DC-TAOX61 Analog Output Input/Output Termination Assembly

Configured for high-integrity control signal distribution and 1:1 redundant analog output management in Experion PKS Series C architectures, the Honeywell DC-TAOX61 (DC-TAOX61 Analog Output IOTA) provides direct physical/electrical execution.

Hardware Specifications

1:1 Redundancy Switching & 4-20 mA HART Loop Protocols

The DC-TAOX61 IOTA provides a robust 1:1 redundant termination platform engineered to mount dual Series C analog output modules (such as CC-TAOX61). Integrated current-limiting circuitry and transient surge suppression on every channel terminal safeguard internal control electronics from field short-circuits and inductive voltage spikes. The assembly supports standard 4-20 mA outputs with transparent HART pass-through capabilities, ensuring uninterrupted control execution and continuous diagnostic data access for field actuators and positioners during active module failovers.

Frequently Asked Questions

Q: What redundancy configuration is supported by the DC-TAOX61 Termination Assembly?

A: The IOTA features a 1:1 redundant footprint that accepts dual Series C analog output modules to guarantee zero-process-interruption loop execution during failover events.

Q: Does the DC-TAOX61 IOTA support HART-enabled field instrumentation?

A: Yes, the unit fully supports HART communication pass-through, allowing bi-directional digital diagnostic data transmission over standard 4-20 mA analog control loops.

Q: What is the maximum load resistance supported on the analog output channels?

A: Each channel supports a maximum load resistance of up to 750 ohms when operating at nominal 24 VDC loop voltage.

Field Installation Guidelines

• Mount the DC-TAOX61 IOTA securely onto a standard Series C channel rail inside the control cabinet, verifying that the mechanical mounting latches lock firmly in place.

• Terminate field actuator and control valve wiring to the plug-in screw or clamp terminals, ensuring correct polarity for 4-20 mA current loops.

• Route analog output signal cables through dedicated, grounded wire trays separated physically from high-voltage AC power and motor drive feeds.

• Connect the main cabinet earth ground bar directly to the IOTA grounding lug using a low-impedance copper conductor to maintain transient surge suppression and Zone 2 safety compliance.
