P2266 30 Relay / RS232 Communication BMS Interface
The P2266 BMS Interface is designed to monitor up to 200 networked inputs. Networked input information is obtained from other panels connected to the network
Output is via relay contacts or RS232 serial communications. RS422 serial communications is yet to be implemented.
Each networked input can be programmed to have any number of relay outputs or serial codes assigned to it which will be activated when the input is in the alarm condition.
The relay outputs operate in such a way so that if power is lost to the unit, the relays become active, indicating that there is a problem.
The serial communications work by a simple handshaking routine, with the main BMS system sending a “Get” code to the P2266, which responds by sending the alarm details of each input that has been programmed into it.
The P2266 then finalises the transaction with an “End” code. Each input can have an ON code (for when the input is in alarm) and an OFF code (for when the input is normal).
Network connection is made directly to the main electronics via an eight-way telephone style plug.
Relay output is made by a set of terminal blocks. Each relay has a designated number from 1 to 30 and has a normally open contact, a normally closed contact, and a common. RS232 serial communications is made via a four-way telephone style plug.
If networking is not required, it can be disabled by removing a plug in link on the main PCB, the unit then relies on input gathering from the RS232 serial communications or RS422 serial communications.
All P2266 programming is done via a four way RS232 plug and socket that couples it to a computer. This feature permits full custom set up of the IO Sets. The connector for this function is marked as “PANEL/SETUP”
