Features:
- Honeywell lists MC-GHAO11 as a coated 16-output GI/IS analog FTA with a HART connector and no standby-manual connectors.
- The FTA is specified for use only with MU-PAOY22; the family table identifies 4-20 mA outputs and GHAO11-specific load/compliance limits.
- Honeywell's redundancy-option table gives a 20 ms maximum output gap on failover; verify the actual redundant IOP/FTA design before application.
Honeywell's TPS Process Manager I/O specification (IO03-684, December 2012, Revision 2) lists MC-GHAO11 as the coated GI/IS analog-output FTA for 16 outputs, without standby-manual connectors and with a HART connector. The model table states that it is used only with MU-PAOY22 and that the MC models are conformally coated. The associated GHAO11 family specification is 4-20 mA with 16 channels. The document does not separately associate listing suffix 51309540-175 with this model, so that numeric mapping must be confirmed from the supplied item label.
Before installation, verify the complete FTA and IOP labels, approved I/O drawings, field-device and intrinsic-safety loop design, HART connector arrangement, redundancy use, and terminal/wiring details. Compare the loop burden with the GHAO11 family values under the stated supply condition; do not generalize ratings from the other 16-point FTA models in the same table. Follow the applicable Honeywell installation and safety instructions, and test each affected channel and alarm or failover behavior under the site's approved commissioning procedure before process release.
The MC-GHAO11 51309540-175 Honeywell GI/IS Analog Output FTA may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell MC-GHAO11 51309540-175 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
Honeywell lists MC-GHAO11 as the coated GI/IS analog-output FTA with a HART connector, without standby-manual connectors, for use only with MU-PAOY22. Confirm the exact FTA and IOP labels, connector style, coating and approved configuration. The model row does not independently map numeric order suffix 51309540-175 to MC-GHAO11.
The GHAO11 family table states 16 channels of 4-20 mA, an 870-ohm maximum resistive load at 20 mA and 17.4 V maximum compliant output under the stated 24 V supply = 20 V condition. It lists +/-0.45% calibrated accuracy at 25 C including linearity for MU-GHAO11. Apply these family figures only after confirming the exact matched IOP, supply and loop conditions; do not borrow limits from the other FTA models.
Honeywell's redundancy-option table lists a 20 ms maximum output gap on failover and switching-hardware diagnostics once per minute. The catalog marks the FTA for single or redundant applications, but the installed IOP, wiring and logic determine the actual arrangement. Confirm the intrinsic-safety design and approved process state, and test channels and failover under site procedures before return to service.
