TB1 - Digital Output Connections
The TB1 connector (labeled
DIGITAL
OUTPUTS
) provides eight digital (common ground) output
connections designed to drive externally-mounted relays or other indicating circuits. Each output can
sink up to 100 mA of the current. External circuitry (relays, indicators, etc.) must be powered from an
external power supply of the same voltage used to power the AMI (12 to 24 V dc). The ground (or dc
common) terminals of the external power supply must be tied to TB1-1 and/or TB1-10. Refer to the TB1
terminal block assignment chart and Figure 2 below.
If the application includes the Model 12584-001 I/O Control Module, please refer to Pub. 42004-359 for
installation, connection and specification details.
N
OTE
: All outputs are programmed using AMI Configuration software. Each output must be
programmed before it can activate.
