Category : RS-485 I/O Expansion Racks

RU-87Pn I/O expansion units are used to expand I-87K series I/O modules via the RS-485 interface. They are equipped with one power module, one RS-485 interface, one CPU module and several I/O slots. High profile I-87K series I/O modules can be plugged into the unit. RU-87Pn series I/O Expansion Racks have auto configuration. Each slot configuration can be pre-configured and stored in the CPU module. Once a module is plugged in, the CPU module will write the pre-configured data to the module. They are also hot swappable.
