LOCAL I/O EXPANSION FOR GATEWAYS AND MODBUS MASTERS
OleumTech® provides a fast and economical solution for expanding local input/output (I/O) counts to any OleumTech Wireless Gateways or Modbus Master devices with the RS485 I/O Expansion System. The RS485 I/O Expansion System does not require any software or programming, making it one the of the easiest local I/O expansion solutions available.
The RS485 I/O Expansion System accepts 9-30 VDC and RS485 Interface Module controls data traffic and distributes the power to connected I/O Modules over the DataRail®, which minimizes wiring. Modbus slave IDs are assigned using the rotary ID switch dial available on each I/O Module.
EXPANSION KIT – JUST ADD I/O
To build a RS485 I/O Expansion System, a RS485 Expansion Kit is required. It includes a RS485 Interface Module and all the mounting hardware for installing onto 35 mm DIN rails. Users simply add desired I/O Modules to the system. The supplied DataRails supports up to five pairs of I/O Modules to a system in any I/O combination. One system can support up to sixteen pairs of I/O Modules using optional longer length DataRails.
