PCO100FD10 - Carel RS485 MODBUS FIELD SERIAL CARD FOR pCO Sistema

Field bus RS485 serial boards create a serial interface that allows the pCO1 to communicate with other devices via various standards. In fact, the tLAN, MP bus and RS485 options connect the pCO1/ pCO3 / pCO5 to a network of devices, including actuators, probes, expansions or terminals.

Electrically insulated RS485 serial option

The PCO100FD10 option is used to connect the pCO1/ pCO3 / pCO5, via an electrically insulated interface, to an RS485 network, using the connector with removable terminals on the card. The controller consequently acts as the MASTER (i.e. supervisor), and therefore other pCO controllers or SLAVE devices can also be connected. The PCO100FD10 optional card acts as the SLAVE. The meaning of the pins on the connector are denoted by the silk-screening on the card. A maximum of 207 devices can be connected using this type of connection. If the PCO100FD10 optional card occupies the last position on the supervisor serial line and the line is longer than 100m, the line must be terminated by connecting a 120 Ω - 1/4W resistor to the terminal pins.
