Description

IS420YDIAS1B Discrete Input Module

The Discrete Input (IS420YDIAS1B) I/O pack provides the electrical interface between one or two I/O Ethernet networks and a discrete input terminal board. The YDIA contains a common processor board and an acquisition board specific to the discrete input function. The YDIA I/O pack accepts up to 24 contact inputs and terminal board specific feedback signals, and supports three different voltage levels.

System input to the pack is through dual RJ-45 Ethernet connectors and a three-pin power input. Discrete signal input is through a DC-37 pin connector that connects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs.

Contact Input Module:

The Mark* VIeS Functional Safety Contact Input module provides an interface between discrete contact process sensors (24 discrete inputs) and Mark VIeS Safety control logic.

The Contact Input module consists of two orderable parts: the contact input I/Opack and the contact input terminal board. All safety contact input modules use the same I/Opack, IS420YDIAS1B. Multiple DIN-rail mounted terminal boards are available to provide the necessary contact voltages, redundancy, and terminal block styles.

The Contact Input module is available in both Simplex and Triple Modular Redundant (TMR) configurations. Users can select the configuration that best addresses their needs for availability and SIL level. This document discusses the Simplex Contact Input (STCI) terminal board and the Contact Input (TBCI) terminal board. The TBCI terminal board offers TMR capability but it can also be used in a Simplex configuration with a single YDIA I/Opack. In a TMR I/Oconfiguration, the controller performs 2-out-of-3 voting on the discrete inputs. In a Dual I/Oconfiguration, the controllers listen to the first reporting YDIA I/Opack.
