ABB S800 I/O Modules ABB DO818 Digital Output Module product description
The DO818 is a 32 channel 24 V digital output module for the S800 I/O. This module has 16 digital outputs. The output voltage range is 12 to 32 volt and the maximum continuous output current is 0.5 A.
The outputs are protected against short circuits, over voltage and over temperature. The outputs are divided into two individually isolated groups with 16 output channels and one voltage supervision input in each group.
Each output channel consists of a short circuit and over temperature protected high side driver, EMC protection components, inductive load suppression, output state indication LED and optical isolation barrier. The process voltage supervision input give channel error signals if the voltage disappears. The error signal can be read through the ModuleBus.
The channel-wise high side drivers are short circuit and over temperature protected.
The outputs are provided with a current limitation that enters a repetitive switched mode after an initial peak current has been exceeded. The initial peak short circuit current limit is set to IL(SCp) (typ 1.4A). During the repetitive mode short circuit current, the limit is set to IL(SCr) (typ1.1A). If this operation leads to an overtemperature condition, over 135°C, a second protection level (Tj > 135°C) changes the output into a low duty cycle PWM (selective thermal shutdown with restart) to prevent critical chip temperatures. If base chip temperature reaches a critical temperature, all 8 outputs are turned off. The output circuitry will shut off if the process power drops below 11V.
The I/O signals are connected to the MTU with the process connector. Three different types of MTUs can be used. The extended MTU (TU830) provides 32 outputs terminals and 16 return terminals. The compact MTU (TU818) provides 1- wire connection to the load. The compact MTU (TU819) has two D-sub 25 pin connectors for interfacing with the process.
