Why choose SLI230CRP
Built for a defined industrial duty
Use SLI230CRP to bring a 240 VAC field signal safely to a 24 VDC PLC input or similar low-current control load. It is especially useful where long cables, capacitive coupling and induced voltages could otherwise cause uncertain input behaviour.
80 nF cable capacitance
A published capability for long-field-cable applications.
Only 1 µA leakage
A clearly specified low off-state current on the PLC-input side.
Pulse-transformer isolation
4,600 VAC RMS / 1 s test voltage between field and controller sides.
Application guidance
Use it where its strengths matter
Suitable applications
- 240 VAC field signals to PLC inputs
- Long field cables with known capacitance
- Low-current DC control inputs
- Industrial panels requiring galvanic field/controller isolation
Check before selection
- Use the relay for PLC inputs and similar low-current loads; maximum load current is 50 mA.
- If switching an inductive load, install a clamp diode across the load as required by the datasheet.
- Check cable capacitance against the 80 nF specification and verify the actual field voltage.
- Apply thermal derating and horizontal mounting guidance for dense installations.
Delcon design advantage: the control command crosses a pulse-transformer isolation barrier. The model-specific solid-state output stage is then selected for the actual AC, DC or PLC-input duty. See how the technology works →

Frequently asked questions
SLI230CRP selection basics
What does SLI230CRP connect?
It accepts a nominal 240 VAC field signal and provides a solid-state DC output intended for PLC inputs and similar loads.
How does it help with long cables?
The datasheet specifies 80 nF cable capacitance together with 160 VAC turn-on and 140 VAC turn-off thresholds, giving the designer published limits for the field circuit.
What is the off-state leakage current?
The specified output leakage current is 1 µA. Always confirm that value against the PLC input requirements.
Can it drive an inductive load?
It is intended for PLC inputs and similar loads. If an inductive load is used, the datasheet requires a clamp diode across the load.
