Here is a cheat sheet we use to identify where and what each connection on the DNS80 spin boards are connected to.   This specific unit has connections for SC2, SCN5, SCN3, SN4, SCN6, SCN8, SCN10, SCN12 and SCN13 on the EESC-0012 spin board.

 

 

 

 

 

 

 

 

 

 

 

 

 

Connector	Board	Description	Where does it go ?
SCN2	EESC-0012 Spin Board A	Board A Input 1-30, Output 1-8, 24V, 12V, GND	External Alarm IFC
SCN3	EESC-0012 Spin Board A	Inputs 1-38. Outputs 1-7, but there are really 32 serparate outputs	Mech I/O to Spin mechanical section IFC Board
SCN4	EESC-0012 Spin Board A	Inputs 1-8. 4 Inputs for M3 control. 4 outputs for M3.	SCN4A Cup Section
SCN5	EESC-0012 Spin Board B	Inputs 1-32, Outputs 1-24, 24V, 12V, GND	Spin Chemical IFC
SCN6	EESC-0012 Spin Board B	Only has one input and output	AC power supply interface
SCN8	EESC-0012 Spin Board B	Inputs 1-12, Outputs 1-8	Not Connected
SCN10	EESC-0012 Spin Board C	TXA, RXA, RS232	AC power supply interface
SCN11	No Connector
SCN12	EESC-0012 Spin Board C	BUS1+ , BUS1-	RS485 to Chemical Temperature Controller, AKA “Thermostatic Control Unit”
SCN13	EESC-0012 Spin Board C	BUS2+ , BUS2- TXB2, RXB2	Not Connected
