SPECIFICATIONS
1. POWER: Power will be supplied by the Graphite host device. Some
modules, depending on usage may consume high levels of power. This may
limit the total number of modules that can be installed on a single Graphite
host. Check the Graphite module and Graphite host data sheets for specific
usage and power requirements.
GMSG1 Max Power: 5.6 W
2. LEDs*:
STS - Status LED shows module condition.
OP1, OP2, OP3 - Indicate status of outputs 1, 2, and 3
ALM - Alarm LED is lit during any internal alarm condition.
* Default configuration.
3. MEMORY: Non-volatile memory retains all programmable parameters.
