The IOBD board for the 211 is the previous gen one with the external solid state relays soldered on the board. Looks to have all inputs outputs and parameters pretty close just labeled differently on the board. Do you know if there are any differences between the 2 boards other than labeling. Pretty remote site figure i will be out there again in a week or 2. The iobd board on the unit is ABA26800TS and the units i have on route that pin out exactly as prints showing soft starter addition is ACA26800YA.
