2.2 Options
The O2iM can be factory configured for specific applications. Some variations are:
• 5-Relay Terminal board. Each relay may be set up to close on high O2, low O2, or both.
Two additional relays indicate system OK status and sample flow/pressure status. The four
relays may also be assigned as individual channel alarms when the multipoint scan option is
installed.

any of our remote indicators) for one hour if the external power is interrupted
