DRY CONTACT OUTPUT MODULES
G4 Family Data Book 47
Dry Contact Output Modules
Description
Opto 22’s G4 family of modules includes two dry-contact,
low-contact-resistance DC output modules, the G4ODC5R and the
G4ODC5R5.
The G4ODC5R is a single-pole, single-throw, normally open mechanical
relay (Form A, SPST-NO). The G4ODC5R5 is a single-pole, single-throw,
normally closed mechanical relay (Form B, SPST-NC).
Typical applications for these dry-contact modules include analog signal
and communication line multiplexing.

NOTE: The power rating of the dry
contact mofule must not exceed 10
VA under steady-state or
momentary in-rush conditions.
For voltages at or below 20 volts,
the current limit is 0.5 amps. For
voltages above 20 volts, the
maximum allowable current
isdetermined by the following
equation:
See next page for additional
information.
