Product Description: Honeywell SDW-550EC module
The SDW-550EC digital input module has sixteen channels for either loopmonitored loops or status signals derived from proximity switches, as set inDIN 19234 (NAMUR).
The module also supports monitoring of earth faults thatoccur within these sixteen loops.
The SDW-550EC module can be used in applications up to SIL 3, in compliancewith 1EC 61508.
The power for the connected field devices is supplied by an on-board DC/DCconverter common to all sixteen channels.LEDs on the front of the module indicate the status of the channel, loop andmodule diagnostics.
The input of proximity switch signals to the SDW-550EC module needs to beconverted to a level that is suitable for the SDW-550EC module. To enable thisconversion, you need to place the signal converter module SDW-550EC programming connector Px on the back of the IO backplane in the IO chassis.
