The JMC1616 is an IO expansion module designed for industrial automation, featuring a balanced architecture of 16-channel NPN digital inputs and 16-channel sink digital outputs with a single-channel drive capacity of 1A, suitable for resistive, inductive and lamp loads. Compatible with JMC-101 controllers and JMC.ECT couplers, it realizes signal interaction via a high-speed 100M parallel bus and supports optocoupler isolation with a withstand voltage of 500V for anti-interference and stable signal transmission in industrial environments. Compact in size and powered by 24VDC, it can be seamlessly integrated into existing automation systems, providing an efficient signal expansion solution for production line monitoring and equipment control.
