Key issues

Question 1: What is the core difference between TSX P57-10 and P57-20?

Answer: The core difference lies in the expansion capability: P57-10 supports a maximum of 512 discrete I/O points and 2 racks; P57-20 supports 1024 point I/O, 8 racks, and has larger memory, faster execution speed, and expandable 128K memory cards.

Question 2: What are the exclusive functions of DEY16FK high-speed input module compared to ordinary DI module?

Answer: Equipped with 0.1-7.5ms programmable filtering, pulse state latch (capturing short pulses), 16 input interrupt event processing, faster response, suitable for high-speed counting and fast signal acquisition.

Question 3: What is the fault protection and recovery mechanism of the DSY series output module?

Answer: The transistor output has short-circuit/overload automatic disconnection; Relays/thyristors are protected by replaceable fuses. After a fault, it supports automatic retry every 10 seconds or manual program restart, and can be configured to output hold/set 0/set 1 in case of a fault.
