Description:
The DO821 is an 8 channel 230 V a.c./d.c. relay (NC) output module for the S800 I/O. The maximum output voltage is 250 V a.c. and the maximum continuous output current is 3 A. All outputs are individually isolated. Each output channel consists of optical isolation barrier, output state indication LED, relay driver, relay and EMC protection components. The relay supply voltage supervision, derived from the 24 V distributed on the ModuleBus, gives an error signal if the voltage disappears, and the Warning LED turns on. The error signal can be read via the ModuleBus. This supervision can be enabled/disabled with a parameter.
S800 I/O is a comprehensive, distributed and modular process I/O system. The system can communicate with host controllers and PLCs via industrial standard fieldbuses. Due to its wide connectivity, it is suitable for a wide range of process controllers and PLCs from ABB and other companies. Allowing installation in the field, close to sensors and actuators, S800 I/O reduces installation costs by reducing wiring costs. With features such as "hot swapping" of modules, online reconfiguration and redundancy options, it helps to maintain production, thereby increasing profits.
