Fig. 18 references, page 20
1. Power supply terminal 24V~50-60 Hz 15VA or 24V
10W (see note on page 25)
2. Telephone-type terminal for connective to the user terminal unit (MMI-Man Machine Interface)
3. Real-time clock board (optional)
4. RS422/RS485 optoinsulated board (optional) for connection to a serial line of supervision/telemaintenance
5. Pin strip for analog-input adopter board (eventually available upon request only)
6. EPROM with application program
7. Jumpers to select the local network communication mode
J8 in position 1-2 allows the connection of the board to a terminal unit or, possibly, to the supervisory; in position
2-3 only the connection to the local network is enabled
J9 in position 1-2 enables the supervisor to reset the pCO board, in position 2-3 makes the pCO board
independent of the reset action of the supervisor
The interface pCO boards by Carel have both jumpers in position 1-2
Caution: in this EPROM not exists the local network” management
