B1 LEFT SIDE EXPANSION MODULES
Modules connected to the B1 series on the left include communication modules and analog I/O modules:
- Communication modules
The main unit of B1-PLC has one built-in communication port (port 0, RS232 interface).Expansion of communication ports can be achieved by employing Communication Module (CM). The available models of CM for B1 are listed in the table below.
- Analog I/O modules
Expandable analog modules from the left in the B1 series include analog input, analog output and temperature modules. Their measurement accuracy is 12 bits. The available analog models of B1 are listed in the table below.
