Honeywell FC-SDO-0424 Safe digital output module

Honeywell FC-SDO-0424 Safe digital output module 

Description

The safe digital output module SDO-0424 has four 24 V DC, 2 A output channels to drive loads up to 50 W. The maximum module load is 6 A.

These loads may be resistive (such as lamps) or inductive (such as solenoids). For inductive loads, a suppression diode is included on each output. The outputs, including the suppression diodes, are fully tested and may therefore be used for safe applications.

Within the configured Diagnostic Test Interval, the outputs are tested for:

Ability to de-energize the output,

Ability to de-energize the group (via secondary means),

Crosstalk between outputs, and Functioning of the suppression diodes.

The external 24 V DC supply is split into two groups of two outputs each. Each group has its own secondary means of de-energizing.

A secondary means of de-energizing (SMOD) enables the watchdog and the processor to de-energize the outputs, irrespective of the result of the application function.
