Ethernet Remote I/O Modules
Semaphore offers a new range of affordable Ethernet Remote Modules of compact size and monoblock construction that can be fixed easily on DIN rail.
The modules connect a wide variety of electrical, electronic,
and mechanical devices and sensors -- such as pumps, temperature
and pressure transmitters, motors, and more — to computers
and applications over standard Ethernet networks (Modbus/TCP),
RS485 (Modbus RTU), or other controllers and PLCs.
Each remote I/O module has its own Ethernet Modbus TCP/IP port making it easy to connect the modules to each other with up to 100 meters of CAT5 cable, or even longer distances using fiber optic switches.
There are several types of Ethernet remote I/O modules available with different I/O formats.
| Reference | COM1 | COM2 | COM3 | Digital Inputs | DO Relays | Dig In or Out | Analog Inputs | Temp Inputs | Analog Outputs | Counters |
| RM-200 | Ethernet | RS232 | RS485 | - | 4 | 8 | 6 | 2 | 0 | 2 |
| RM-201 | Ethernet | RS232 | RS485 | - | 4 | 8 | 2 | 6 | 0 | 2 |
| RM-300 | Ethernet | RS232 | RS485 | 4 | 0 | 16 | 8 | 0 | 2 | 2 |
Compact Ethernet Remote I/O Modules are easily mounted on a standard DIN rail.
