New Honeywell MC-GHAO21 51305869-175 Module In Stock

Product Description

The redundant model MC-GHAO11 and MC-GHAO21 Analog Output (AO) FTAs isolate up to sixteen 4-20 mA signals that can drive current-to-pressure (I/P) transducers, position actuators, or any load of 870 ohms or less, from an associated Analog Output IOP. The following table summarizes typical FTA functions pertinent to these models for planning reference.

Function Description

- Fault-line detection

In the event of an open or short circuit in the field wiring,

the resistance sensed at the input to the Galvanic

Isolation Module will be a high value. This permits the

readback feature of the associated 4-20 mA Analog

Output IOP to detect the open or shorted field circuit and

report a soft failure to the user.

- Signal connectors

  • Two 50-pin connectors on the redundant model of the

FTA provide the interfaces to one or two IOPs.

  • A 20-pin connector that provides the interface to an

external HART multiplexer.

  • The two 2-pin power connectors that provide the

interfaces to the GI/IS Power Distribution Panel.

- Field wiring output signals

The FTA provides, nominally, 4-20 mA for control of field

devices that are Galvanically Isolated from all other

circuits. The load resistance can be no greater than 870

ohms. The signal output’s dynamic impedance is greater

than 1 megohm.

- Calibration terminals

Four screw terminals are provided on the FTA, two pairs

for calibrating the primary and secondary IOPs. A touch

pad is provided that initiates the calibration procedure in

primary or secondary IOP.

- Indicators

  • A green indicator on the FTA illuminates when the

primary IOP (A) is active.

  • A green indicator on each Galvanic Isolation Module

illuminates when power is applied to the module.

- Current consumption

  • Both models of the FTA consume 928 mA at 24 Vdc

with a 20 mA signal on all outputs.

  • The power dissipation for the FTA is 21.6 watts with all

outputs providing 20 mA of current.
