Analog Output Signal Characteristics
The CC-TAOX01 provides 16 analog output channels for current-loop signal handling. The specified output range includes the standard 4-20 mA operating span, with a directly settable range of 2.9 mA to 21.1 mA and a separate 0 mA setting.
The maximum resistive load is 800 ohms. The maximum output compliance voltage is 16 V, while the maximum open-circuit voltage is 22 V. These limits should be considered when selecting field devices and evaluating loop resistance.
The specified calibrated accuracy is +/- 0.35% of full scale at 25 deg C, including linearity. Output readback accuracy is specified separately at +/- 4% of full scale; these values describe different performance characteristics and should not be treated as interchangeable.
Frequently Asked Questions (FAQ)
Q: How many analog output channels does the CC-TAOX01 support?
A: The board is specified for 16 analog output channels. Each channel uses a current output signal, with 4-20 mA as the stated signal type.
Q: What is the maximum field-loop resistive load?
A: The specified maximum resistive load is 800 ohms. Confirm that the total loop resistance and connected device requirements remain within the applicable output compliance limits.
Q: Is the CC-TAOX01 a redundant output board?
A: No. The supplied product information identifies this IOTA board as non-redundant. A redundant system configuration should not be assumed from the board specification alone.
Field Installation Guidelines
- Verify the board model and part number before installation: CC-TAOX01, 51308351-175.
- Confirm the applicable Honeywell system configuration and compatible analog output module before connecting field wiring.
- Check field-device polarity, loop resistance, and power requirements against the system documentation.
- Keep analog signal wiring separated from high-current and high-voltage conductors to reduce electrical interference.
- Apply cable shielding and grounding according to the system installation manual and site grounding standards. Avoid creating unintended ground loops.
- Confirm that the installation environment does not exceed the specified maximum operating temperature of 60 deg C.
- Inspect the board and connectors for physical damage before installation. Follow the manufacturer’s procedures for isolation, insertion, removal, and commissioning.
- Do not assume hot-swap capability, channel-to-channel isolation, or redundant operation unless the applicable Honeywell documentation explicitly confirms these functions.
