RM10 

Remote I/O Module in RS485 ModBus

           The “RM10” is a module that combines Analog Inputs and Digital Inputs/Outputs. It is an efficient and economical solution for remote command and control of remote I/O’s. A field bus based on the industrial standard Modbus RTU allows a RS485 communication with Master unit (SCADA package, TBOX CPU,  PLC,...). The “RM10” module is based on an aluminum anodized enclosure. It is easily clipsed on a DIN rail without the need for specific tools. Various LED’s are displayed on the front side.

 

Bus 
  
The bus runs on 4 wires: 2 for the RS485 and 2 for the power supply of the module (between 9 and 28 Volts). The transmission speed can be set between 1.200 and 115.200 baud. A  maximum of 255 modules can communicate simultaneously over a distance that can exceed severa1 kilometers. 

Inputs/Outputs 
  4 Analog Inputs can be selected individually as 4 - 20 mA, 0 - 10 V or temperature sensors Pt100, Pt1000, Ni1000 on 2 or 3 wires. 

4 Digital Inputs or Outputs 12 to 24 Vdc with internal protection against short circuits. In the case of the Inputs, a power supply output (max. 1 mA) is available to avoid the necessity of using an external power supply.
