More Information

Overview Manuals Output Circuits Ex Wiring Isolation Installation

Features:

  • Four fail-safe output circuits switch approved Ex i field loads through the assigned terminal module.
  • Electrical isolation separates the output group from both the backplane bus and the load-voltage bus.
  • Mechanical coding and hazardous-area enclosure rules control installation and module exchange.
Siemens 6ES7138-7FD00-0AB0 provides four intrinsically safe fail-safe outputs in an ET 200iSP station.

The output circuits of 6ES7138-7FD00-0AB0 connect through a coded TM-IM/EM or TM-EM/EM terminal module.

Safety data and conductor separation determine which field actuators may be connected to 6ES7138-7FD00-0AB0.

The Siemens 6ES7138-7FD00-0AB0 SIMATIC ET 200iSP 4-Channel Fail-Safe Digital Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Fail-Safe Switching Path

  • Field loads: The four circuits switch solenoid valves, DC relays, indicator lamps, or actuators.
  • Output data: Each circuit is governed by the documented 17.4 V/40 mA Ex i boundary.
  • Parallel use: No more than two output current circuits may be combined when the specified certification data are observed.
  • Power path: Load-bus current supplies the output stage while the backplane carries module control and diagnostics.

Intrinsic-Safety Boundaries

  • Line separation: Intrinsically safe and non-intrinsically safe conductors use separate cable ducts.
  • Field zones: The connected actuator zone and device category must agree with the permitted hazardous-area arrangement.
  • Entity values: Uo, Io, Po, Co, and Lo must remain compatible with the complete field circuit and cable.
  • Enclosure: Zone 1 uses an Ex e enclosure, while Zone 2 requires at least the specified IP54 enclosure protection.

Electrical Separation

  • Backplane: The output channels are isolated from the ET 200iSP backplane bus.
  • Load bus: The output group is isolated from the load-voltage power bus.
  • Channels: The four output channels are not isolated from one another.
  • Circuit check: Fault analysis must therefore distinguish shared channel potential from the two isolated system boundaries.

Terminal Base and Exchange

  • Terminal base: The electronic module plugs into a TM-IM/EM or TM-EM/EM terminal module.
  • Mechanical code: First insertion creates a coding element that blocks an incorrect module type.
  • Damage check: Only an undamaged electronic module may be connected to the terminal base.
  • Live exchange: Insertion or removal in Zone 1 or Zone 2 follows the enclosure-opening limits for the installed ET 200iSP station.
Description
Siemens 6ES7138-7FD00-0AB0 is a fail-safe SIMATIC ET 200iSP electronic module with four 17.4 V/40 mA Ex i digital outputs. It switches solenoid valves, DC relays, indicator lamps, and actuators while the ET 200iSP backplane carries control and diagnostic data.

Installed in a TM-IM/EM or TM-EM/EM terminal module, 6ES7138-7FD00-0AB0 separates each output circuit from the backplane bus and the load-voltage bus. The four channels share a common potential relationship because the channels are not isolated from one another.

For hazardous-area wiring, 6ES7138-7FD00-0AB0 keeps intrinsically safe conductors separate from non-intrinsically safe conductors. Actuators in Zones 0, 1, 2, 20, 21, and 22 can connect through the terminal module when their voltage, current, power, capacitance, and inductance values remain within the module safety data.

The mechanical coding created when 6ES7138-7FD00-0AB0 is first inserted prevents a different module type from being fitted to the terminal base. In Zone 1 or Zone 2, insertion and removal during operation are limited by the specified enclosure and hazardous-area installation conditions.

Technical notes
Isolation on Siemens 6ES7138-7FD00-0AB0 separates the channels from the backplane and load bus, but not from one another.

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 does 6ES7138-7FD00-0AB0 reject an actuator even when the nominal voltage appears correct?
Compare the 6ES7138-7FD00-0AB0 Uo, Io, Po, Co, and Lo limits with the actuator certificate and the complete cable contribution.
Why can all four outputs on 6ES7138-7FD00-0AB0 be affected by one wiring error?
The 6ES7138-7FD00-0AB0 channels are not isolated from one another, so check shared potential paths, terminal assignments, and load-bus wiring.
What should be checked when 6ES7138-7FD00-0AB0 will not seat in the terminal module?
Verify the 6ES7138-7FD00-0AB0 terminal-module type, mechanical coding element, connector condition, module orientation, and absence of physical damage.
Why does 6ES7138-7FD00-0AB0 require separate cable ducts?
The 6ES7138-7FD00-0AB0 hazardous-area wiring rules require strict separation of intrinsically safe and non-intrinsically safe conductors.
Can 6ES7138-7FD00-0AB0 be exchanged while the ET 200iSP station is operating?
The 6ES7138-7FD00-0AB0 may be exchanged in Zone 1 or Zone 2 only under the specified enclosure and operating conditions.
What causes excessive load-bus consumption on 6ES7138-7FD00-0AB0?
Check the 6ES7138-7FD00-0AB0 connected loads, parallel circuits, wiring faults, output states, and the 510 mA maximum load-bus current.
