I/O Module Functions • High Level Analog Input /HART Input Module (16pt) – The High Level Analog Input Module supports both highlevel analog and HART inputs. Analog inputs are typically 4-20mA DC for both traditional and HART devices. HARTdata can be used for status and configuration. HART data, such as the secondary and tertiary variables, can also beused as process control variables. • High Level Analog Input (16pt) - The High Level Analog Input Modulesupports high level analog inputs Analog inputs are typically 4-20mA DC fortraditional devices. • Analog Output/HART Output Module (16pt) – The Analog Output Modulesupports both standard 4-20mA DC outputs and HART transmitter outputs. • Analog Output (16pt) – The Analog Output Module supports standard 4-20mA DC outputs. • Digital Input 24 VDC (32pt) – Digital input sensing for 24V signals • Digital Output 24 VDC (32 pt) – Current sinking digital outputs. Outputs are electronically short-circuit protected. • Temperature Multiplexer (64pt). – Provides thermocouple (TC) and resistance temperature device (RTD) inputs.The Multiplexer supports up to four, field proven termination assemblies FTAs. • Digital Input Sequence of Events - Accepts 24VDC discrete signals as discrete inputs. The inputs can be timetagged to support 1ms resolution Sequence of Events

Features All Series C components feature an innovative design that supports enhanced heat management. This unique lookprovides a significant reduction in overall size for the equivalent function. The unique features of Series C I/O include: • I/O Module and field terminations are combined in the same area. The I/O Module is pluggedinto the IOTA to eliminate the need for a separate chassis to hold the electronics assemblies. • Two level “detachable” terminals for landing the field wiring in the enclosure, providing easierplant installation and maintenance. • Field power is supplied through the IOTA, with no need for extra power supplies and theassociated craft wired marshalling. • Redundancy is available directly on the IOTA without any external cabling or redundancy controldevices, by simply adding a second IOM to an IOTA. • The Series C innovative styling is one of its unique features. This styling includes features tofacilitate the effective use of control hardware in a systems environment. These features include: • Vertical mounting for more effective wiring since most field wiring applications require entry from the top or bottom ofthe systems cabinet. • An “information circle” for a quick visual cue to draw the Maintenance Technician’s eye to important statusinformation. • “Tilted” design for effective heat management within the cabinet enclosure. Since Series C allows for a significantincrease in cabinet density, an effective heat management system is critical for high systems availability. • Input and output circuits are protected from shorts to alleviate the need for in-line fusing, reducing installation andmaintenance costs.
