ROC800-Series Power Input Modules

The Power Input Modules for the ROC800-Series Remote

Operations Controller (ROC800) provide the ROC800 with

the ability to convert external input power to the voltage

levels required by its electronics. Three types of Power Input

Modules are available for the ROC800: 12 Vdc (PM-12), 24

Vdc (PM-24), and 30 Vdc (PM-30).

12 Volt dc Module

With the 12 Vdc module, the ROC800 can accept 12 Vdc

(nominal) input power from an AC/DC converter or other

12 Vdc 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 you to monitor a

voltage, such as an external charging source.

The AUX+ and AUX– terminals can be used to supply reverse

polarity protected voltage (12 V) to external devices, such as

a radio or solenoid.

The AUX

+ and AUX

– terminals can be used to provide

switched power for external devices.

24 Volt dc Module

With the 24 Vdc module, the ROC800 can accept 24 Vdc

(nominal) input power from an AC/DC converter or other

24 Vdc supply fused and connected to the + and – terminals.

The AUX+ and AUX– terminals can be used to supply reverse

polarity protected voltage (12 V) to external devices, such as

a radio or solenoid.

30 Volt dc Module

With the 30 Vdc module, the ROC800 can accept 11 to

30 Vdc (nominal) input power from an AC/DC converter or

other 11 to 30 Vdc supply. The input source should be fused

and connected to the + and – terminals.

The AUX+ and AUX– can be used to supply reverse polarity

protected voltage (Voltage output follows input) to external

devices, such as a radio or solenoid.

The AUX

+ and AUX

– terminals can be used to provide

switched power for external devices.

Compatibility and Installation

You can install and remove a Power Input Module from the

module slot, when not under power, by removing the two

captive screws accessible from the front of the unit.

Note: The design of the PM-30 and PM-24 power modules

does not include the low voltage cutoff feature

present in the PM-12 module: should power fall

below the set LoLo alarm (a default of 10.1 V), the

PM-12 module ceases to provide power to the

backplane. Thus, the module shuts down CPU

operations. For the PM-24 and PM-30 modules, when

power falls below the LoLo alarm point, the CPU goes

into sleep mode. In sleep mode, the backplane still

receives power, the DO modules continue to hold

their logic, but nothing controls I/O at this point. If

you need both the increased power capacity offered

by the PM-30 and low voltage cutoff, refer to the

options provided in the description of the PM-30

module in Chapter 3 of the ROC800-Series Remote

Operations Controller Instruction Manual (part

D301217X012).
