2. Compatibility & Expandability

Same-brand Compatibility

ABB DO810 is designed for ABB AC800M DCS rack system. On-site automation technicians stack multiple ABB DO810 onto cabinet backplane to increase digital output resources during plant renovation. ABB DO810 fits standard rack slots and links ABB main CPU and base terminal modules without transitional adapters. Manual address setting on module surface lets ABB DO810 match original ABB field solenoid valves and contactors.

Cross-brand Compatibility

Proprietary backplane bus blocks direct hardware access of ABB DO810 to third-party control equipment. Additional protocol converter is essential to connect ABB DO810 with Siemens and Schneider PLC hosts. Common 24V digital signal norms make ABB DO810 compatible with most aftermarket external relays with no internal circuit alteration.
