Bus Driver
Module
The bus driver module contains the circuitry that interfaces with the CPU module
and the system modules. The bus driver module is equipped with two Style Y or
Z, limited energy signaling circuits and a city tie circuit.
The bus driver module provides the system with the following :
•
Controls default alarm bus if the CPU fails
•
Monitors system modules for placement
•
Monitors system for ground faults
•
Watchdog circuit
•
Programmable Signal Circuits (1 & 2)
•
Auxiliary Power Outputs (A+/A-, S+/S-, +/- 12VDC)
The internal circuitry draws about 18mA from the +24V power supply with both
signal circuits terminated with a 3.9K ohm resistor (with no current draw on the
city tie circuit). Each relay on the bus driver module draws 22mA when activated.
In normal operation only the trouble relay is energized.
City Tie
Programming The bus driver module contains three jumpers for city tie programming (J1, J2, &
J3) located in the center of the board. These three jumpers are used to select the
reverse polarity or the master box option for the city tie connection.
