More Information

Overview Manuals Redundant Outputs Power Routing Field Terminals HART Access

Features:

  • Eight current-output channels terminate paired ET 200M module signals at removable field connectors.
  • Dual power inputs and two fused module connectors support the documented redundant arrangement.
  • Each channel provides shield terminals and a HART handheld access point.
Current outputs from the two module connectors are diode-ORed before reaching the assigned field loop.

Power LEDs distinguish the two incoming feeds, while module-fuse LEDs identify the powered I/O path.

Current-mode configuration and the load-resistance limit belong to the complete output loop.

The Siemens 6ES7650-1AB51-2XX0 Redundant Analog Output MTA may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Following two module signals to one field loop

  • Module J1: The first analog output module connects through the J1 interface and its dedicated fuse.
  • Module J2: The second module connects through J2 when redundant operation is required.
  • Diode combining: Paired module outputs are diode-ORed before the current reaches CHx+.
  • Single-module use: A non-redundant installation connects one module to either J1 or J2.

Distributing two incoming DC feeds

  • Feed A: The L+A and MA connector supplies the A input and its presence LED.
  • Feed B: The L+B and MB connector supplies the independent B input and indicator.
  • Internal OR path: Diode ORing lets either valid feed energize the MTA and connected modules.
  • Fuse separation: A separate 1 A fuse protects the power path to each module connector.

Organizing current-loop and shield conductors

  • Current source: CHx+ carries the analog current toward the field load.
  • Current return: CHx- completes the assigned loop back to the termination assembly.
  • Shield point: SHx accepts the cable shield for each channel.
  • Earth path: The ground stud and shield jumpers control the screen connection to earth.

Connecting a handheld terminal without changing channel identity

  • Per-channel point: Each of the eight outputs has a dedicated HART access connection.
  • Loop association: The handheld terminal remains tied to the selected current-output channel.
  • Current mode: The connected analog module is configured for current-mode operation.
  • Load boundary: Series diodes require the complete loop load to remain below 600 ohms.
Description
Siemens 6ES7650-1AB51-2XX0 is the eight-channel analog output marshalled termination assembly for SIMATIC PCS 7 ET 200M, linking redundant 6ES7332-5HF00-0AB0 output modules to field current loops.

Two removable power feeds enter 6ES7650-1AB51-2XX0 and are diode-ORed so either source can power the assembly and the connected I/O modules. Separate fuses and LEDs then identify the supply available to each module connector.

Outputs from J1 and J2 on 6ES7650-1AB51-2XX0 pass through paired diodes before reaching CHx+ and CHx- field terminals. A redundant installation uses both module connectors, while a non-redundant installation uses either J1 or J2.

Each channel of 6ES7650-1AB51-2XX0 includes shield termination and a HART handheld connection. The removable field connector carries the current-loop conductors, while the ground stud and shield jumpers define the cable-screen path.

For 6ES7650-1AB51-2XX0, the analog module must be configured for current mode and the output load remains below 600 ohms. The MTA does not provide channel-to-channel isolation, and its series diodes reduce the available compliance voltage.

Technical notes
Dual module connectors and diode-OR current paths let Siemens 6ES7650-1AB51-2XX0 combine redundant analog outputs before they reach the field terminals.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can one side of Siemens 6ES7650-1AB51-2XX0 remain powered after the other DC feed is removed?
The A and B inputs of Siemens 6ES7650-1AB51-2XX0 are diode-ORed, so either valid source can feed the MTA and module power paths. Compare both power LEDs to identify which supply remains present.
Which module must be paired with 6ES7650-1AB51-2XX0?
The 6ES7650-1AB51-2XX0 is documented for the eight-channel 6ES7332-5HF00-0AB0 analog output module at E-Stand 3 or higher. Check that exact module identity before connecting the interconnecting cable.
A field loop connected to 6ES7650-1AB51-2XX0 will not reach its expected current; what limit matters?
Keep the total loop load for 6ES7650-1AB51-2XX0 below 600 ohms because its series combining diodes reduce the remaining compliance voltage. Also confirm current-mode configuration and the assigned CHx polarity.
How are two redundant analog modules combined by 6ES7650-1AB51-2XX0?
Outputs from J1 and J2 on 6ES7650-1AB51-2XX0 pass through paired diodes before joining the matching CHx+ field terminal. Each module retains a separate fused power path.
What does a dark Module 1 or Module 2 fuse LED mean on 6ES7650-1AB51-2XX0?
On 6ES7650-1AB51-2XX0, compare the A/B supply LEDs first, then inspect the 1 A fuse assigned to the dark module connector. This separates a missing input supply from an open module-power fuse.
Can channel wiring on 6ES7650-1AB51-2XX0 be treated as isolated from every other output?
No. The 6ES7650-1AB51-2XX0 does not provide channel-to-channel isolation, even though each loop has its own CHx+, CHx- and shield terminals. Preserve the documented common and shielding arrangement.
