Series 8 24V 51454471-175 8C-PDILA1 Digital Input Module

8C-PDILA1 Digital Input Module Series 8 Digital Input 24 V Module P/N 51454471-175

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 • Latched, pulsed or pulse-width modulated output (per channel) • Galvanic Isolation (System to Field only with external user supplied power) 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. A wiring option on the IOTA determines if outputs are referenced to the Series 8 system power or an external field power source. 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.

Function 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. Notable Features • Galvanic isolation • Isolated Dry Contact • Counter EMF Snubbing Circuit • LED indication for each channel ON condition

C300 Controller execution environments The C300 Controller supports three Execution Environment (EE) function blocks. One is the Control EE block, (CEEC300). The other two are I/O Link blocks, (IOLINK). The IOLINK blocks in the C300 support connection and communication with all Series 8 I/O modules. CEE function block The CEEC300 block provides an execution and scheduling environment in which Control Modules (CMs) and Sequential Control Modules (SCMs) execute userconfigured control strategies. Existing control strategies can be ported to a C300 controller, although manual editing of these strategies is required to support the C300 controller configuration. The CEEC300 block contains a peer-to-peer communications layer which is used to communicate between other controllers.

IOLink function blocks Two IOLINK function blocks, which represent the 2 physical IO links on the C300 Controller IOTA, provide the user-configured I/O Link interface to support communications with Series 8 I/O modules. Each IOLINK is configured to support Series 8 I/O modules or 'No Link' if no I/O control is required. Each IOLINK supports redundant and non-redundant communications. I/O modules supported by the C300 Controller The C300 Controller supports Series 8 I/O modules. Series 8 I/O modules are connected to the C300 by a pair of I/O Link Interfaces. Two IO Link interfaces, which are redundant, provide connection between the C300 controller and associated I/O modules. Each IO links can be configured to support Series 8 I/O modules.
