ABB 3BSE020838R1 DO840 Digital Output Redundant or singleS800 I/OModule
The ABB DO840 Module is a 16 channel 24 V digital output module for single or redundant application. This module has 16 digital outputs. The maximum continuous output current per channel is 0.5 A. The outputs are current limited and protected against over temperature. The outputs are divided into two groups with eight output channels and one voltage supervision input in each group.In addition to the four module LEDs, DO840 has one LED (Yellow/Red) per channel (16) that indicate output state and channel error (Yellow = output is energized, Off = output is de-energized, Red = channel error).DO840 is installed with TU830/TU833 Extended MTU Process Connections and is installed on a TU830/TU833 Extended MTU

How to replace the ABB DO840 module?
| Module Type | Comments |
|
DO840,DO810, DO814,DO815, DO880, DO890 Digital Output |
Replacement with power applied is possible. It may be necessary to set the process device manually to a safe state before the module is extracted. Turning locking mechanism deactivates the module. If DO880 is removed from the MTU, the connected output is automatically turned to safe state (de-energized) |
|
DI810, DI811, DI814, DI820, DI821, DI890 Digital Input |
Replacement with power applied is possible. Turning locking mechanism deactivates the module. |
|
DI825, DI830, DI831, DI840, DI880, DI885 Digital Input with SOE |
Replacement with power applied is possible. Turning locking mechanism deactivates the module. |
