2. Compatibility & Expandability

Same-brand Compatibility

ABB DAI01 fits the ABB Freelance DCS system rack structure. Field automation technicians fix multiple ABB DAI01 on rack backboard to raise analog signal collection capacity during workshop transformation. ABB DAI01 locks into standard card slots and connects ABB main controller and base terminal modules without extra transition accessories. Manual dial setting on module surface lets ABB DAI01 match original ABB field transmitters deployed in industrial sites.

Cross-brand Compatibility

Proprietary rack bus design forbids direct wiring connection of ABB DAI01 with non-ABB control hardware. External protocol conversion equipment becomes necessary to link ABB DAI01 to PLC products manufactured by Siemens or Schneider. Common industrial analog signal specifications support ABB DAI01 to access various third-party two-wire sensors with no internal circuit refitting.
