Relay Option Card Installation
The Relay Option Card provides four normally open relays for an 880 indicator when installed. The Relay Option Card attaches
to the 880 CPU board. Depending on the desired output of the Relay Option Card, SLOT 1 must be configured in the Setpoints
Menu (SETPTS) and BIT 1-4 in the Digital I/O Menu (DIGIO) within the Setup Menu of the 880 indicator. Refer to the 880
Technical Manual (158387) for additional information on the configuration of relays.
The indicator automatically recognizes all installed option cards when the unit is powered on. No hardware-specific
configuration is required to identify an installed option card to the system.
Manuals and additional resources are available from the Rice Lake Weighing Systems website at
Warranty information can be found on the website at
Always disconnect power before opening an enclosure or controller assembly. Option card is not hot swappable.
Procedures requiring work inside the indicator must be performed by qualified service personnel only.
A grounding wrist strap must be worn to protect components from electrostatic discharge (ESD) when working
inside an enclosure or controller assembly.
