07EA90-SI ABB modules are used to convert analog signals to digital signals and transmit them to 

the control system for monitoring and controlling industrial processes.

These accuracy settings are only used when negotiating for time mastership with 

other nodes in the underlying Harmony control network.

Features and benefits

Termination for up to eight (8) analog I/O process signals within a horizontal row.

All SD I/O modules & bases of all types (Singular or Redundant) AND (Compact or Full-size), are

100% fully compatible with each other. Thus, Singular & Redundant, Compact or Full-size I/O

modules can be mounted within a single, common HN800 I/O bus.

Optional mechanical keying can be implemented to prevent insertion of the wrong I/O module type.

Latching device on the base locks the base into position on DIN-Rail.

Industry standard 35-mm DIN rail, Horizontal row mounting.

Comprehensive self-diagnostics

Comprehensive self-diagnostics continuously monitor the modules and report any errors through LEDs on

the module fronts and through alarm messages and indications to process operator stations.

Malfunctioning inputs can be disabled and simulated by manual entry while failing outputs are deactivated

or driven to a predetermined safe state automatically.

All I/O modules can be replaced while the system is in service. 

Some modules can even be arranged, trans parently into dually redundant configurations forenhanced availability.

Master Update Period

Master update period is the frequency that Harmony Server synchronizes time with 

the underlying Harmony control network. This property is used only when Time 

Synchronization is enabled. The permissible values are 120 to 3540 seconds.

On-board processing capabilities

The process I/O modules are “intelligent” in the sense that module-related signal and data processing is

performed on board as opposed to centrally, by the CPU of the host controller. Time tagging of events,

filtering and gain control are some examples of board-level tasks. 

This functional distribution improves real-time performance and reliability of the 

system as a whole and maintains processing capacity when the system is expanded.
