Core Technical Characteristics
This module is equipped with 16 fully independent SPDT relay output channels, each supporting configurable normally open (NO) and normally closed (NC) contact modes to adapt to diverse on-site control logic. Each relay contact features stable load capacity, with a rating of 10A at 250VAC and 1A at 48VDC, meeting mainstream industrial alarm and interlock load requirements. It supports flexible parameter configuration, including an adjustable 0–30 seconds output delay to filter transient signal disturbances and prevent false equipment trips. Up to 30 sets of customizable Boolean logic expressions are available, enabling flexible combination of alarm and interlock triggers for different rotating equipment working conditions. The module adopts hot-swap design, allowing online replacement and maintenance without powering down or interrupting the entire monitoring system, effectively reducing equipment downtime. It has a low maximum power consumption of 6W, supporting long-term continuous operation. All configuration parameters are protected by password to avoid unauthorized modification and ensure system operation safety. In addition, the standardized compact rack-mounted structure saves cabinet installation space and delivers excellent stability and anti-interference performance for harsh industrial scenarios.
