RP20 Digital Expansion Modules provide additional I/O functionality for the AK8x0 CPU, a powerful EtherCAT Bus CoDeSys Motion Controller, as well as the RP20C Remote I/O EtherCAT Bus Coupler. The RP20s are designed to offer customers versatile and flexible solution possibilities. With their robust industrial design and manufacturing quality, outstanding performance, and comprehensive feature integration, the AK8xM + RP20 are not only widely applicable in the field of general industrial automation, but are also highly suitable for various specialized smart sectors, such as building automation, agricultural intelligence, energy monitoring, and energy management. This series has various modules with 16-channel digital transistor outputs with either PNP (RP20-0016DTP) or NPN (RP20-0016DTN) outputs, a 16-channel digital input module that supports sourcing and sinking types (RP20-1600DT) or a module that has both 8 digital transistor PNP outputs and 8 digital sourcing inputs (RP20-0016DTP).
