PRODUCT DESCRIPTION
KFD2-STC4-EX1 SMART Transmitter Power Supply
Pepperl+Fuchs KFD2-STC4-EX1 is a single-channel SMART transmitter power supply and isolated barrier in the K-System. It powers a compatible field transmitter and transfers its analog current signal to the control side while supporting documented bidirectional SMART communication.
The unit uses a 20–35 V DC supply and supports 0/4–20 mA output with the specified load limits. Screw terminals, DIN-rail mounting and the documented intrinsically safe field circuits support process instrumentation; electrical entity parameters and hazardous-location markings must be matched to the connected device.

SYSTEM INTEGRATION
Integrate KFD2-STC4-EX1 smart transmitter power supply
Match the exact KFD2-STC4-EX1 variant and transmitter arrangement. Compare the intrinsically safe circuit parameters with the connected device and cable.
Allocate a 20–35 V DC supply and the documented 0/4–20 mA control-side load. Use the applicable terminal allocation for the transmitter or current-source configuration.
Validate the configured analog signal and SMART communication path. Retain the final circuit assessment, wiring and hazardous-location documentation.
Features:
- Single-channel transmitter power and signal isolation
- 20–35 V DC supply and 0/4–20 mA output
- Matched intrinsic-safety circuit parameters
The KFD2-STC4-EX1 smart transmitter power supply requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify KFD2-STC4-EX1 smart transmitter power supply
Compare plain Ex1 with any proposed .H, .2O or other suffix variant. Different wiring and output arrangements require an explicit compatibility check.
Record supply, field terminals, control-side load and hazardous-location marking. Follow the manufacturer isolation and qualified-personnel instructions.
After replacement, verify transmitter power, signal transfer and communication under the documented circuit limits. Archive the accepted wiring and model identity.
Features:
- Plain Ex1 suffix and terminal configuration
- Preserved field circuit and control-side load
- Analog transfer and SMART communication checks
The KFD2-STC4-EX1 smart transmitter power supply requires replacement verification against the complete installed configuration and current manufacturer documentation.

-
How many transmitter channels does the plain Ex1 version support?
KFD2-STC4-Ex1 is a single-channel unit. Do not replace its data with the Ex1.2O or .H version without checking the exact variant. -
What DC supply range applies to KFD2-STC4-EX1?
The documented rated range is 20–35 V DC. -
What analog output and load limits are specified?
The product data lists 0/4–20 mA with a 0–800 Ω load at 20 mA. -
What voltage is available to the transmitter at 20 mA?
The exact product data specifies at least 16 V at terminals 1 and 3. -
Does the barrier specification replace an intrinsic-safety circuit calculation?
No. The applicable field-circuit entity parameters and connected-device/cable limits must be checked together. -
What is the stated settling time for this barrier?
The product data specifies 200 µs, with 20 µs rise/fall time. -
What transmitter and entity details should accompany an Ex1 barrier request?
Specify the plain KFD2-STC4-EX1 variant, transmitter circuit, hazardous-location marking, field entity parameters and required output load. -
Which barrier markings and circuit connectors should be checked upon receipt?
Compare the plain Ex1 suffix and approval markings, inspect field/control/supply terminals and verify the permitted transmitter wiring. Retain the circuit assessment before connection.
