Technical FAQs

Is the IS200SRLYH2AAA designed specifically for Mark VI systems?
Yes. This module is engineered exclusively for GE Mark VI control platforms.
What kind of outputs does this module provide?
It delivers discrete relay-based outputs for on/off control and signaling.
Is this a redundant or simplex module?
It is a simplex relay output module intended for single-channel applications.
Can it be used for safety-related switching?
It is commonly used for interlocks and permissive logic when applied within approved system designs.
Does it require field-side isolation hardware?
The relay design already provides electrical isolation between control and field circuits.
Is the module suitable for continuous operation?
Yes. It is designed for continuous duty in industrial control environments.
How is configuration handled?
All configuration is managed through the Mark VI control system rather than on the module itself.
Can it control inductive loads like solenoids?
Yes, provided standard industrial suppression practices are followed.
Is this module commonly used for replacements?
Very much so. It is a frequent choice for direct replacements in existing Mark VI racks.
Why choose a relay module over solid-state outputs?
Relay outputs offer physical contact separation, making them ideal for certain legacy and safety-driven applications.
