CIRCUTOR CVM-B Series - Manual (Page 9)

- 2 digital inputs, to select the tariff, detect the logic state of external signals or as act
as an impulse input.
- 2 transistor digital outputs, fully programmable.
- 2 relay digital outputs, fully programmable.
- RS-485 communications, with two serial protocols: MODBUS RTU ® and BACnet.
The CVM-B can be expanded with the following expansion modules:
 M-CVM-AB-8I-8OTR, expansion module with 8 transistor digital inputs and 8 tran-
sistor digital outputs.
 M-CVM-AB-8I-8OR, expansion module with 8 relay digital inputs and 8 relay digital
outputs.
 M-CVM-AB-4AI-8AO, expansion module with 4 analogue inputs and 8 analogue out
puts.
 M-CVM-AB-Modbus/TCP( Bridge), expansion module for connecting the unit to a
Modbus/TCP network and as an Ethernet to RS-485 gateway.
 M-CVM-AB-LON, expansion module for connecting the unit to a LonWorks network.
 M-CVM-AB-Profibus, expansion module for connecting the unit to a Profibus network.
 M-CVM-AB-MBus, expansion module for connecting the unit to a M-Bus network.
 M-CVM-AB-Datalogger, expansion module that can be used to store data in the em-
bedded PowerStudio platform integrated in the module.
