Power Input Modules (for ROC800-Series)
 |
The ROC809 uses one Power Input Module to convert external input power to the voltage levels required by the ROC809 unit’s electronics and to monitor voltage levels to ensure proper operation.
Two types of power input modules are available for the ROC809: 12 Volt DC and 24 Volt DC.
Power Input Modules can easily be installed or removed from the module slot, when not under power, by removing the two captive screws accessible from the front of the unit. The modules are self-identifying via ROCLINK™ 800 Configuration Software.
With the 12 VDC module, the ROC809 can accept 12 Volts DC (nominal) input power from an AC/DC converter or other 12 Volt DC supply. The input source should be fused and connected to the BAT+ and BAT– terminals. The CHG+ and CHG–
terminals provide functionality similar to an Analog
Input channel and allow the user to monitor a voltage, such as an external charging source. The AUX+ and AUX- terminals can be used to supply reverse polarity protected source voltage to external devices, such as a radio or solenoid. The AUXSW+ and AUXSW- terminals can be used to provide switched power for external devices.
With the 24 VDC module, the ROC809 can accept 24 Volts DC (nominal) input power from an AC/DC converter or other 24 Volt DC supply fused and connected to the + and – terminals. The AUX+ and AUX- terminals can be used to supply reverse
polarity protected source voltage (12 Volts) to external devices, such as a radio or solenoid.
