ABB AC500-eCo DO573 Digital Output Module — 16-Channel Relay Output for Saudi Industrial Control
The ABB DO573 digital output module provides 16 relay outputs for the AC500-eCo PLC platform — rated for industrial control applications in Saudi Arabia where reliable relay switching is essential for valve actuation, contactor control, and alarm signaling in water treatment and petrochemical facilities.
AC500-eCo digital output modules are specified for Saudi municipal and industrial automation projects where relay-contact isolation protects PLC inputs from field voltage transients common in Saudi industrial environments with variable power quality and lightning exposure.
Key Features
16 Relay Outputs: Form C (changeover) contacts rated 2A/250V AC for general-purpose industrial switching.
Galvanic Isolation: Each relay contact isolated from the PLC bus — prevents ground loops and voltage interference.
LED Status Indication: Individual LED per channel for troubleshooting in the field without PC connectivity.
Plug-in Terminal: Removable terminal block for easy field wiring and maintenance.
Applications
Municipal Water Valve Control: DO573 actuates pneumatic valve actuators in Jeddah water distribution networks.
Alarm Annunciation: DO573 drives visual and audible alarm stacks in Dammam industrial facility alarm systems.
