More Information

Overview Manuals Relay Contacts Power Paths Module Links Installation

Features:

  • Ten Form C relay contacts provide separate normally open, common and normally closed field terminals.
  • Two module connectors allow the assembly to accept a single or redundant F-DO10 arrangement.
  • A/B power inputs are combined before module and channel fuses distribute supply.
Between ET 200M F-DO10 module connectors and removable field terminals, the 6ES7650-1AM31-6XX0 keeps the control-module and load-wiring sides distinct.

Each relay channel has its own fuse, while each module connection has a separate power fuse and indicator.

The mounting orientation affects the permissible temperature range; the vertical limit changes if only the upper five channels are used.

The Siemens 6ES7650-1AM31-6XX0 Failsafe Relay Output MTA may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How one output reaches the field

  • Relay path: Each F-DO10 output drives a relay coil through its channel fuse.
  • Normally open: NO and COM close together when the associated relay energizes.
  • Normally closed: NC and COM form the closed path while that relay is not energized.
  • Field removal: The removable field connector separates load wiring from the MTA during wiring work.

A/B supply and fuse chain

  • Input A: The L+A and MA connector brings one DC supply into the assembly.
  • Input B: L+B and MB provide a second supply path for the redundant arrangement.
  • Distribution: The two inputs are diode-combined before module and channel fuses feed their respective paths.
  • LEDs: Separate input and module-fuse indicators show which portion of the path lacks power.

Single and redundant module connection

  • Module 1: One F-DO10 module can connect to the first MTA connector.
  • Module 2: A second connector accepts another module in the redundant arrangement.
  • Single-module option: A non-redundant configuration uses either module connector.
  • Cable boundary: The documented interconnecting cable carries ten output channels between ET 200M module and MTA.

Termination and mounting conditions

  • Rail: The housing installs on a 35 mm deep top-hat DIN rail.
  • Power connectors: A and B input terminals are removable and screw-retained.
  • Shield ground: The shield stud connects the cable shield to earth ground.
  • Thermal orientation: Horizontal and vertical mounting have different operating limits, with a separate vertical allowance for CH5–CH9 only.
Description
For SIMATIC PCS 7 ET 200M, Siemens 6ES7650-1AM31-6XX0 acts as a redundant ten-channel failsafe relay-output marshalled termination assembly. It carries output commands from the F-DO10 module connection to individually fused relay contacts for field wiring.

At 6ES7650-1AM31-6XX0, two I/O-module connectors accept the single-module arrangement or one module on each connector for redundant operation. The relay coil path is associated with the module connections through each channel fuse, while the field side offers normally open, common and normally closed contacts.

Power enters 6ES7650-1AM31-6XX0 through separate A and B removable connectors. The input paths are diode-combined inside the MTA, then distributed through module and channel fuses; LEDs distinguish input-power presence from module-fuse condition.

The 6ES7650-1AM31-6XX0 mounts on a DIN rail and brings field wiring to removable terminations. Its permitted ambient temperature changes with mounting orientation and, in the vertical arrangement, with whether only channels CH5–CH9 are active.

Technical notes
Two I/O-module connectors on Siemens 6ES7650-1AM31-6XX0 accept single or redundant F-DO10 operation; A/B power feeds enter the MTA separately before feeding its fused circuits.

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.
Which ET 200M output module connects to 6ES7650-1AM31-6XX0?
The Siemens 6ES7650-1AM31-6XX0 MTA is specified for the ten-channel failsafe output module 6ES7326-2BF10-0AB0 at E-Stand 3 or higher; verify that revision before wiring.
Can 6ES7650-1AM31-6XX0 run with only one F-DO10 module?
Yes. A non-redundant 6ES7650-1AM31-6XX0 arrangement connects one module to either Module 1 or Module 2; redundant operation uses one module on each connector.
Which field contacts on 6ES7650-1AM31-6XX0 are closed before a relay energizes?
For each 6ES7650-1AM31-6XX0 channel, NC and COM form the closed path when the relay is not energized; NO and COM serve the energized path.
What should be separated when the A POWER LED is off on 6ES7650-1AM31-6XX0?
An unlit A POWER LED on 6ES7650-1AM31-6XX0 points to the A input supply path; check that input rather than assuming the module-fuse or field-contact path is at fault.
Does vertical mounting change the permitted temperature for 6ES7650-1AM31-6XX0?
Yes. Siemens rates 6ES7650-1AM31-6XX0 from −25 to +40 °C vertically with all channels; the upper limit reaches +60 °C only when CH5–CH9 alone are used.
How can a module-fuse problem be distinguished from missing input supply on 6ES7650-1AM31-6XX0?
The 6ES7650-1AM31-6XX0 has separate A/B input-power LEDs and Module 1/2 fuse LEDs, allowing the two supply stages to be checked independently.
