They provide isolation but have slower switching speeds than transistors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I use this module with both NPN and PNP sensors?\u003c\/strong\u003e\u003cbr\u003eYes, the inputs are bipolar and accept both sourcing (PNP) and sinking (NPN) sensors. This makes the \u003cstrong\u003eF5-MD1616R\u003c\/strong\u003e very flexible.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is the maximum switching frequency for relays?\u003c\/strong\u003e\u003cbr\u003eFor mechanical relays, we recommend less than 1Hz for full electrical life. For higher frequencies, consider transistor output modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes this module work with the Flexem FC5 CPU?\u003c\/strong\u003e\u003cbr\u003eYes, it connects directly to any Flexem FC5 CPU via the expansion bus. The system automatically detects the module.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDo I need external fuses for outputs?\u003c\/strong\u003e\u003cbr\u003eWe recommend external fuses or circuit breakers for each common group to protect against short circuits, as relays do not have built-in protection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e© 2026 \u003ca href=\"https:\/\/www.ubestplc.com\/\" target=\"_blank\"\u003eUbest Automation Limited\u003c\/a\u003e.
