Product details
EPM-S202 Lenze Digital Input Module, I/O System 1000
EPM-S202 is an eight-channel digital input module from Lenze. It belongs to the I/O System 1000. The card reads binary signals from switches and proximity switches. It uses NPN logic and IEC 61131 type 1 input behavior. Mount it on the backplane bus next to an EPM-S1xx bus coupler. The coupler handles the fieldbus, so this module stays simple and reliable.

Expert Review
The EPM-S202 does one job well: it reads eight NPN sensors fast and cleanly. The 3 mA input current is gentle on small proximity switches. Isolation to the backplane bus adds safety in mixed cabinets. Its narrow 12.5 mm body saves rail space. This is a solid, low-risk part for standard machine builds.
Manager’s Insight
Most buyers pair this card with a coupler in the same order. Suggest a bundle to cut freight cost. Keep a few units on the shelf, since input cards fail more often than couplers. The 12-month warranty and 12 to 24 hour dispatch keep repeat orders flowing.
Best Fit Equipment and Applications
- Machine panels with many NPN sensors
- Conveyor and handling lines
- Packaging and filling machines
- Small cells that use the Lenze I/O System 1000
- Retrofit jobs that expand an existing backplane
FAQ
- Can this card talk to a fieldbus on its own?
- No. It needs an EPM-S1xx bus coupler on the same backplane.
- What sensor type should I use?
- NPN sensors. PNP sensors will not switch this input correctly.
- From experience, what causes false input signals?
- Long unshielded sensor cables. Keep runs short and away from motor cables.
- How many slots does one module take?
- One slot. The body is 12.5 mm wide.
- How should I plan a purchase?
- Count your NPN inputs, add 20 percent spare, then order couplers and cards together. All parts carry a 12-month warranty and leave stock in 12 to 24 hours by FedEx, UPS or DHL.
