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).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. 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.
