FQA

Q：What input voltages does the DT-1314 module support, and what field devices can it interface with?

A：The DT-1314 supports 4 digital input channels compatible with either 110VAC or 220VAC. It can directly acquire signals from field devices—such as relay contacts, contactors, or push buttons—via dry contacts or active outputs, and works with both 2-wire and 3-wire digital sensors.

Q：What electrical safety and noise immunity features does the DT-1314 offer?

A：All four channels are fully isolated from each other to prevent crosstalk. Combined with a high-speed redundant backplane bus, pluggable terminal blocks, and configurable input signal holding time, the module ensures safe and stable operation in high-voltage industrial environments.

Q：How can I monitor the input status of the DT-1314, and is it easy to install and maintain?

A：Each channel has a dedicated LED indicator for real-time status visibility. With pluggable spring-clamp terminals, the module enables rapid wiring and tool-free replacement—greatly simplifying on-site installation, commissioning, and maintenance.
