Features:
- Eight binary output channels connect the controller to plant-side relay circuits.
- Relay contacts provide electrical isolation between controller signals and field outputs.
- LED indicators support local checks of module and supply conditions.
The SB70 is the eight-output relay interface configuration for SIMATIC TDC and FM 458-1DP systems.
It adapts controller-side output signals to plant circuits through relay contacts, supporting discrete actuator and interlock commands.
Confirm load voltage, contact assignment, cable selection and system wiring before installation or replacement.

- Switch discrete plant loads from SIMATIC TDC or FM 458-1DP output logic.
- Use relay output circuits where controller-side electrical separation from the field is required.
- Apply the module in discrete control paths such as actuator commands and interlocks.
- The documented host systems are SIMATIC TDC and FM 458-1DP.
- Siemens identifies the SC62 cable for connecting this interface-module family to system components.
- Confirm the signal-module connector and the assigned output channel before selecting a replacement.
- The snap-on housing mounts to a standard mounting rail.
- Controller-side signals enter through flat-cable connector X1, with the supply pair assigned to X3.
- Field wiring uses X2 relay terminals for normally open, normally closed and common contacts.
- LED indicators provide local diagnostic visibility for module operation.
- Relays electrically isolate the controller-side inputs from plant-side output circuits.
- A PTC thermistor protects the cable path after the system-side supply connection.
