Functional Features
Output Capability: Each channel can provide a maximum output current of 500mA, capable of driving resistive or inductive loads up to 12W, and can also connect lamps with a power not exceeding 4W.

Safety Features
Safe Shutdown Function: Equipped with an integrated safe shutdown function, which can ensure the safe shutdown of the system in case of faults, and achieve safe isolation to prevent the spread of faults.
Line Monitoring: Continuously monitors the output lines, and can detect faults such as line open circuits in a timely manner to ensure the reliability of the system.
Undervoltage Tripping: When the input voltage is lower than 16V, the module will trigger undervoltage tripping protection to avoid abnormal operation of the module due to excessively low voltage.
Power Failure Protection: If the L + power supply is interrupted, the module will not output signals to avoid damage to the system caused by misoperation.
Automatic Testing Function: During operation, it can automatically perform tests, including the readback of output signals, the switching capability of test signals, and cross-interference tests (walking bit tests), etc., to ensure the performance and signal integrity of the module.
