DESCRIPTION
Opto 22’s G4 family of modules includes two dry-contact, lowcontact-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).

G4 Dry Contact
Output Modules
Factory Mutual-approved versions of these modules are also available.
Typical applications for these modules include analog signal and
communication line multiplexing.
Because of their low 10 VA rating, these modules are not
recommended for inductive or capacitive loads (even very small
loads), because the inrush current is likely to exceed the 10 VA rating.
IMPORTANT: Applications using 120 VAC are typically NOT suited to
these modules. If you are considering using one of these modules for
any application other than low-voltage purely resistive loads, see the
detailed notes and rating curve on page 2, and call Pre-sales
Engineering for specific guidance.

NOTE: The application of the dry contact
module must not exceed 10 VA under steadystate 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 is determined by the following equation:
Maximum Current = 10 VA / Voltage
