The maximum number of modules that a ROC809 can support is nine. The need for fuses has been eliminated on the Input/Output (I/O) modules through the extensive use of current-limiting short-circuit protection and surge protection techniques. This results in less maintenance for remote locations. The I/O modules are self-resetting after the fault clears. These modules can be installed in any module slot. Modules can easily be installed or removed from the module slots at any time by removing the two captive screws accessible from the front of the unit. Modules are hot-swappable, meaning the module can be removed and another module of the same type can be installed under power. The modules are hot-pluggable, meaning they may be installed directly into unused module slots under power. The modules are also self-identifying via ROCLINK™ 800 Configuration Software. All modules have removable terminal bocks for convenient wiring and servicing. The terminal blocks can accommodate a wide range of wire gauges up to 12 American Wire Gauge (AWG). Each module provides 2500 Volts DC of isolation from other modules and the backplane including power and signal isolation. The DI and PI modules each have their own integrated short-circuit protected isolated power supply. This power supply allows the field circuitry to be completely isolated from backplane and the Central Processor Unit (CPU). This protection limits current during a short-circuit and is auto-recoverable after the fault clears. Light-emitting diodes (LEDs) indicate the current status for each channel of the module. Discrete Inputs The Discrete Input (DI) modules module provides eight channels for measuring discrete inputs. The DI modules monitor the status of relays, open collector/ open drain type solid-state switches, and other two- state devices. Each DI channel can also be software configured to function as a latched DI. A latched DI remains in the active state until reset. Other parameters can invert the field signal and gather statistical information on the number of transitions and the time accumulated in the on or off state. The fastest time that each channel within the module can be read is 250 times per second.

DI and PI Modules (ROC800-Series)Discrete Input (DI) and Pulse Input (PI) modules forthe ROC800-Series Remote Operations Controllerprovide the ROC with the ability to monitor variousdiscrete and pulse input field values. The maximumnumber of modules that a ROC809 can support isnine.
The need for fuses has been eliminated on theInput/Output (I/O) modules through the extensiveuse of current-limiting short-circuit protection andsurge protection techniques. This results in lessmaintenance for remote locations. The I/O modulesare self-resetting after the fault clears.
These modules can be installed in any module slot.Modules can easily be installed or removed from themodule slots at any time by removing the twocaptive screws accessible from the front of the unit.Modules are hot-swappable, meaning the modulecan be removed and another module of the sametype can be installed under power. The modules arehot-pluggable, meaning they may be installeddirectly into unused module slots under power. Themodules are also self-identifying via ROCLINK™800 Configuration Software.
All modules have removable terminal bocks forconvenient wiring and servicing. The terminalblocks can accommodate a wide range of wiregauges up to 12 American Wire Gauge (AWG).
Each module provides 2500 Volts DC of isolationfrom other modules and the backplane includingpower and signal isolation.
The DI and PI modules each have their ownintegrated short-circuit protected isolated powersupply. This power supply allows the field circuitryto be completely isolated from backplane and theCentral Processor Unit (CPU). This protection limitscurrent during a short-circuit and is auto-recoverableafter the fault clears.
Light-emitting diodes (LEDs) indicate the currentstatus for each channel of the module.
Discrete Inputs
The Discrete Input (DI) modules module provideseight channels for measuring discrete inputs. The DImodules monitor the status of relays, open collector/open drain type solid-state switches, and other two-state devices. Each DI channel can also besoftware configured to function as a latched DI. Alatched DI remains in the active state until reset.Other parameters can invert the field signal andgather statistical information on the number oftransitions and the time accumulated in the on or offstate. The fastest time that each channel within themodule can be read is 250 times per second.

Pulse Inputs
The Pulse Input (PI) modules module provides twochannels for measuring either a low speed or highspeed pulse signal. The PI module processessignals from pulse-generating devices and providesa calculated rate or an accumulated total. The PI ismost commonly used to interface to relays or opencollector / open drain type solid-state devices. ThePulse Input can be used to interface to either self-powered or ROC800-Series powered devices. Thehigh speed input supports signals up to 12 KHzwhile the low speed input is used on signals lessthan 125 Hz.
