The ICMK-CS31 is a configurable remote unit for the ABB AC 31 CS31 bus. The 1SBP260057R1001 variant accepts 120 or 230 VAC mains power and provides eight isolated 24 VDC inputs used to set the operating format for the connected extension arrangement.
Replacement roleThe configuration inputs allow the unit to reproduce operating formats used by earlier CS31 Series 30 remote units.

Which supply does 1SBP260057R1001 require?It is the 120/230 VAC version. The 24 VDC version uses order number 1SBP260056R1001.
2
Are the eight inputs normal process inputs?No. They configure the remote unit format for the attached extension type and replacement behavior.
3
Can ICMK-CS31-A1.0 operate without an extension?The unit alone provides the CS31 interface and configuration circuitry; field I/O capacity depends on the connected extension arrangement.
4
What must be supplied with an inquiry?Send the full order number, installed extension types, CS31 station arrangement, supply voltage and clear terminal-label photos.
5
What should be verified after replacement?Confirm mains selection, protective earth, bus polarity, address, input strap pattern and correct I/O behavior for every extension.
