FQA
Q：What types of sensors and input signals is the DT-122F module compatible with?
A：The DT-122F features 16 digital input channels designed for NPN sensors, where a low-level signal (0V) is active. It supports dry contacts, active outputs, and both 2-wire and 3-wire digital sensors—making it ideal for industrial field signal acquisition.
Q：How does the DT-122F ensure reliable capture of input signals?
A：It features a configurable input signal holding function that reliably latches even short-duration pulses. Each channel also has an independent LED indicator for real-time status visibility, simplifying commissioning and troubleshooting.
Q：Is the DT-122F easy to install and integrate into a control system?
A：Yes. Built on a high-speed redundant backplane bus, the module uses pluggable spring-clamp terminals (supporting wire sizes from 0.2 to 1.5 mm² / AWG 24–16), enabling rapid wiring and tool-free replacement for efficient installation and maintenance.
