Digital Output - Bussed 24VDC – CC-PDOB01
Function The Digital Output bussed 24VDC (DO24V) module provides reliable 24V digital output signals to control other process equipment as well as solenoid valves and interposing relays. The DO24V can support high energy outputs to reduce the number of external components in the output loop. Notable Features ? Extensive internal diagnostics to ensure data integrity ? Optional redundancy ? Direct/Reverse output support ? Safe-state (FAILOPT) behaviors ? “Fuse-less” short circuit protection ? Latched, pulsed or pulse-width modulated output (per channel) ? Galvanic isolation 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 C power system. Fuse-less Short Circuit Protection This unique feature allows a short circuit to exist without blowing any fuses. When a particular channel is shorted, internal circuits detect this and remove power to the field connection. The channel remains de-energized until the short circuit is repaired. FAILOPT Series C 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.
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 C power system. A wiring option on the IOTA determines if outputs are referenced to the Series C system power or an external field power source. FAILOPT Series C 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. The Digital Output Relay provides a dry contact for isolated low voltage / low current or high voltage / high current discrete output applications. Each relay supports a Form-A or Form-B output based on jumper configuration. The Relay IOTA uses the Digital Output 24V (DO24V) IOM with a special IOTA to support the Relay IOTA. All characteristics of the DO24V IOM are incorporated here.? Each channel user configurable as: ? Analog Input ? Analog Output ? Digital Input ? DISOE - Sequence of Events (1ms resolution SOE, 20ms PV scan) ? Digital Output ? Pulse Input (any four channels) ? Open Wire Detection ? Electronic short circuit protection1 ? Fast Scan (Priority I/O Module Scan) ? Safe-state (FAILOPT) behaviors configurable on a per channel basis for Digital / Analog Output ? HART 7 support (Analog I/O) ? HART Modem per Channel for Fast Performance ? Extended Temperature Range -40 to +70°C module ambient
