Circutor CVM-A1500 - Page 10

It is a modular device that can be expanded using expansion modules with different functions.
The device features:
- 3 keys that allow you to browse between the various screens and program the device.
- 3 indicator LEDs: CPU, ALARM and on the navigation keys.
- LCD Display, for displaying all parameters.
- 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.
- Built-in Datalogger module, which can be used to check data via a conventional web
browser. The PowerStudio external software is needed to download the data to a PC or
server.
The CVM-A 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 device to a
Modbus/TCP network and as an Ethernet to RS-485 gateway.
 M-CVM-AB-LON, expansion module for connecting the device to a LonWorks net-
work.
 M-CVM-AB-Probus, expansion module for connecting the device to a Probus net-
work.
 M-CVM-AB-MBus, expansion module for connecting the device to a M-Bus network.
 M-CVM-AB-Modbus/TCP(Switch), expansion module for connecting the device to a
Modbus/TCP network and as an Ethernet to Ethernet gateway.
