Modbus RS485 I/O System
BM-1000-PM1K
The Modbus RS485 I/O System provides an easy and cost-effective way to connect local digital and analog devices to any Modbus master, such as SCADA systems or PLCs. This system requires no configuration or network mapping, as each I/O module appears as a slave device on the Modbus network with a pre-configured data map. I/O modules are conveniently powered from the RS485 I/O Expansion module via the DIN rail mounted DataRail backplane. Up to 16 I/O modules can be added to one Modbus network, making it easy to add the devices you need. The system can also be used in conjunction with ProSoft Frequency Hopping radios for remote applications.
