General Description |
|
|
CoolEx is a Modbus I/O extender with analog, digital and PWM inputs
and outputs. CoolEx can be used in conjunction with Programmable
Logic Controller (PLC) or any other Modbus master that requires some
extra I/O or special I/O functionality. CoolEx is controlled by
master by means of standard Modbus requests defined in "Modbus
Application Protocol Specification".
CoolEx physical connection to MODBUS is Two-Wire EIA/TIA-485
standard interface recommended by "Modbus over Serial Line
Specification and Implementation Guide". A number of CoolEx devices
can be connected to single 2W-bus. To utilize CoolEx with TCP/IP
Modbus master over Ethernet network MODBUS 485RTU/TCP Gateway can be
used. |

Features |
|
|
 |
Six independent variable
analog outputs with 0-10V output range
Output Voltage is
determined by corresponding holding register. Output current
is up to 40mA. Analog output can be directly connected to
voltage controlled device like Fan Drive, Pump Drive, Torque
Drive, FRG, Voltage to Frequency converter and so on.

|
|
Six PWM Outputs with
variable frequency and duty cycle
Frequency and duty cycle
controlled independently for each PWM Output via
corresponding holding registers.
