ABB XO08R2 1SBP260109R1001 Relay Output Extension Module

ABB XO08R2 with part number 1SBP260109R1001 belongs to ABB Advant Controller 31 series. It is a relay output expansion module equipped with 8 SPDT changeover contacts, used to expand the digital output capacity of the Advant OCS PLC controller.

Each channel has galvanic isolation to block external surge interference and avoid fault spread to the main controller. It connects to the main controller via the local expansion bus, widely used as spare parts for maintenance and renovation of legacy ABB Advant automation systems.

FAQ

1. Q: Can ABB XO08R2 1SBP260109R1001 run independently without Advant main controller?
   A: It is an expansion module, must be matched with Advant 31 series controller and cannot work alone.
2. Q: What are typical module failure symptoms?
   A: Relay no action, bus communication error, single channel contact damage, module fault alarm light on.
3. Q: How to complete commissioning and diagnosis?
   A: Install on DIN rail, connect expansion bus and field load wiring, test relay switching and bus communication status.
