MNET Series
MNET Series is a family of communication slave products whose digital I/O, analog I/O, temperature sensor inputs, and high-speed pulse I/O can be controlled from a master device such as a PC, HMI, or PLC using Modbus or LS Industrial Systems Cnet.
The CPU module includes DIP switches for setting the baud rate and slave address.
Supports 1 RS-232 channel, 1 RS-485 channel, and 1 UART channel.
This product does not accept downloaded user programs. Select Modbus RTU Slave or LS Industrial Systems Cnet Slave when ordering.
How to read model names
- The leading number in
8A,16A,32A, etc. is the number of digital inputs. - The number before
Ris the number of relay outputs. - The number before
Tis the number of transistor outputs. 8A8Ris a model with 8 digital inputs and 8 relay outputs.8A8Tis a model with 8 digital inputs and 8 transistor outputs.

Optional modules
The following optional modules can be added to the product configuration. The product is assembled and shipped in the selected configuration.
Users cannot add or remove I/O modules or optional modules.
| Code | Function | Points per module | Maximum configuration |
|---|---|---|---|
| X | Analog inputs | 4 points | Up to 5 units, 20 points |
| F | PT100Ω temperature sensor input | 4 points | Up to 5 units, 20 points |
| Y | Analog outputs | 3 points | Up to 4 units, 12 points |
| K | High-speed pulse outputs | 6 points | Up to 2 units, 12 points |
The combined total of analog inputs and PT100Ω temperature sensor inputs cannot exceed 20 points.
The combined total of analog outputs and high-speed pulse outputs cannot exceed 12 points.
Products with optional modules are custom-built, so exchanges or refunds may be difficult.
