More Information

Overview Manuals Compatibility Connectivity Monitoring & Control Diagnostics & Protection

Features:

  • HART communication carried on each 4-20 mA output loop
  • Output settles within 1% of its final value in 80 ms
  • Independent FAILOPT action for every channel
8C-PAOHA1 51454469-275 combines the analog command and HART data on the same field pair, allowing compatible smart instruments to exchange device information without interrupting the control current.

The directly settable span extends from 2.9 to 21.1 mA. With a 22-28 VDC supply, the output can work across a 50-800 ohm loop resistance while maintaining its specified response.

Each channel can hold its last command or move to a configured safe value through FAILOPT. An electronics failure forces the affected output to zero current, and an open loop is reported as a Channel Soft Failure.
The Honeywell 8C-PAOHA1 51454469-275 Analog Output Module is listed as Active / Available from OEM. Apter Power can assist with purchasing inquiries and access to available Honeywell product documentation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Termination choices:

  • Standard base: 8C-TAOXA1 is the coated 6-inch non-redundant IOTA for 8C-PAOHA1 51454469-275.
  • Redundant base: 8C-TAOXB1 is the coated 12-inch IOTA for a redundant output arrangement.
  • Transfer interval: The zero-current gap during redundant switchover is 10 ms maximum.
  • Service method: Removal and insertion of the output module under power is supported.

Smart-device interaction:

  • Overlay communication: HART data shares the same current loop used by 8C-PAOHA1 51454469-275.
  • Device scope: The interface supports compatible HART-capable and multivariable instruments.
  • Loop monitoring: An open field wire is annunciated as a Channel Soft Failure.
  • Channel handling: Diagnostics identify the affected loop without changing the other output channels.

Current-loop performance:

  • Channel format: 8C-PAOHA1 51454469-275 provides sixteen 4-20 mA analog outputs.
  • Command range: Output current can be set directly from 2.9 mA to 21.1 mA.
  • Load range: A 22-28 VDC supply supports 50-800 Ω loop resistance.
  • Settling: The output reaches within one percent of its final value in 80 ms.

Fault-response controls:

  • Self-checking: 8C-PAOHA1 51454469-275 performs internal diagnostics for output integrity.
  • Hold option: FAILOPT can retain the last commanded value on an individual channel.
  • Shed option: FAILOPT can instead drive the channel to its configured safe value.
  • Electronics failure: Loss of IOM electronics forces the affected output to zero current.
Description
8C-PAOHA1 51454469-275 mounts on the coated 8C-TAOXA1 six-inch IOTA for a single output path or the 8C-TAOXB1 twelve-inch IOTA when redundancy is required. The IOTA choice determines the termination layout while the removable IOM retains the same HART analog-output function.

In a redundant arrangement, transfer between modules produces a maximum zero-current gap of 10 ms. Removal and insertion under power are supported, allowing an IOM to be serviced without dismantling the field termination assembly.

Output quality is specified at +/-0.2% of full scale calibrated accuracy at 25 degrees C, with nominal linearity of +/-0.05% of full scale and ripple below 100 mV peak-to-peak across a 250-ohm load. These limits define how closely the current command is reproduced at the field loop.
