Which points does the 549-214 add to an APOGEE Power MEC?

It adds four configurable analog inputs and four analog outputs, providing an HOA-ready 4AI/4AO expansion position.

For 549-214, what supply must be verified before connecting the module?

Use 24 VAC within the documented 20 to 30 VAC, 47 to 63 Hz range and allow for 14 VA consumption at 24 VAC.

For 549-214, which signal types can be assigned to the four analog inputs?

The documented selections are 0-10 V, 4-20 mA, 1 kOhm RTD or the optional 100 kOhm thermistor; preserve each point's configured type and scaling.

For 549-214, which output modes are available on the four analog outputs?

Each documented output can be configured for 0-10 V or 0-20 mA; record the selected mode, range and controlled actuator before rewiring.

For 549-214, how can the expansion module communicate with the controller?

The product data identifies the MEC expansion bus or APOGEE P1 FLN, so the installed connection method and addressing must be preserved.

For 549-214, which expansion-bus limits affect cable replacement?

The documented expansion-bus speed is 38.4 kbit/s and the maximum run is 61 m; retain the approved topology and cable route.

For 549-214, how many expansion modules can the Power MEC support?

The specification allows up to eight supported modules in combination. Confirm the complete installed chain rather than commissioning this module in isolation.

What should be verified after restoring a 549-214?

Check every input type and calibration, command each 0-10 V or 0-20 mA output, verify HOA preparation and confirm the MEC or P1 FLN database reports the correct values.

Information

Overview Manuals Common Applications Product Precautions

Siemens 549-214 is Analog Expansion Module. It adds four configurable analog inputs and four analog outputs to a Power MEC through the expansion bus or P1 FLN.

Adds four analog inputs
Adds four analog outputs
Supports configurable voltage, current and sensor inputs
Operates on the MEC expansion bus or P1 FLN

549-214 operates with APOGEE Power MEC or P1 FLN controller, 24 VAC module supply, documented analog sensors and actuators, approved point database and expansion-bus wiring.

Engineered applications include HVAC analog point expansion, Remote sensor acquisition, Modulating actuator control, Power MEC expansion-module replacement.

Important Notice: Record all point types, ranges, calibration, expansion-bus or FLN address and HOA preparation; isolate 24 VAC and prove each input and output before releasing control.

Important Notice: The first document presents exact-model technical and engineering data. The second provides a separate installation, connection, commissioning and acceptance workflow.

HVAC analog point expansion

Adds mixed analog points to a building-control panel.

Remote sensor acquisition

Acquires remote temperature or process signals.

Modulating actuator control

Commands modulating valves and dampers.

Power MEC expansion-module replacement

Restores an HOA-ready 4AI/4AO expansion position.

Read the applicable Siemens instructions before work. Verify 549-214 and the installed Siemens APOGEE Power MEC point-expansion system configuration.

Verify the complete 549-214 marking and its assigned Siemens APOGEE Power MEC point-expansion system position before work.

Place the connected HVAC analog point expansion process in the approved maintenance state.

Isolate applicable power and four configurable analog inputs and four configurable analog outputs field energy before disconnection.

Record every connector, conductor, address, firmware and software identity before removal.

Use ESD controls and protect keyed interfaces, exposed contacts and electronic assemblies.

Confirm the installed APOGEE Power MEC or P1 FLN controller and 24 VAC module supply against the approved project.

Restore power in a controlled sequence and review device, network and host diagnostics.

Prove the intended remote sensor acquisition function and retain the final test result.
