Digital Output 24Vdc - Honeywell Experion 8 Series Technical Information

Series 8 Controller and I/O Specification, S803-150-500
3.3.10.

Digital Output 24VDC

Function
The Digital Output bussed 24VDC (DO24V) module can switch reliable 24V digital output signals to control other
process equipment as well as solenoid valves and interposing relays.
Notable Features

Extensive internal diagnostics to ensure data
integrity

Optional redundancy

Safe-state (FAILOPT) behaviors
Bussed 24VDC DO
The Digital Output Bussed 24VDC has provisions for both internal and external field power excitation. As a bussed
output device, all of the outputs share a common return (ground). All outputs get their power from the same source,
which can be either the system power supply or an externally connected 24V power supply. When selection is from
an external source, outputs can be galvanically isolated from the Series 8 power system.
Safe-state Behavior (FAILOPT)
Series 8 DO module will support FAILOPT parameter on a per channel basis. The output can be directed by
configuration to either HOLD THE LAST VALUE, or SHED to a SAFE VALUE. The safe value can be configured by
the user.
