ROC364 Specifications
PROCESSOR MEMORY
NEC V25+ running at 8 MHz.
On-Board: 128 KB battery-backed SRAM for data.
32 KB EEPROM for configuration.
FlashPAC: Plug-in module with 512 KB Flash read-
only memory (ROM) and 512 KB of battery-backed
static RAM (SRAM).
Memory Reset: Optional LDP permits a cold start
initialization when used during power-up.
I/O CAPACITY
Up to 16 I/O channels per Module Rack. Up to 4
Module Racks (64 I/O channels) per MCU.
OPERATOR INTERFACE PORT
EIA-232D (RS-232D) serial format for use with
portable operator interface. Baud is selectable from
300 to 19,200 bps. Asynchronous format, 7 or 8-bit
(software selectable). Parity can be odd, even, or
none (software selectable). 9-pin, female D-shell
connector provided.
TIME FUNCTIONS
Clock Type: 32 kHz crystal oscillator with regulated
supply, battery-backed. Year/Month/Day and
Hour/Minute/Second.
Clock Accuracy: 0.01%.
Watchdog Timer: Hardware monitor expires after
1.2 seconds and resets the processor. Processor
restart is automatic.
DIAGNOSTICS
These values are monitored: real-time clock/system
clock compare, AI module mid-scale voltage, DI
module default status, AO module D/A voltage, DO
module latch value, I/O transmitter voltage, power
input voltage, MCU board temperature.
POWER REQUIREMENTS
11 to 16 V dc (12.5 V to start up) or 22 to 30 V dc
(25 V to start up), jumper selectable. 1 Watt typical,
excluding I/O power.
AUXILIARY OUTPUT POWER
Input power is software switched to two sets of
auxiliary output power terminals. Each output fused
for 5 A maximum. Output voltage is 0 to 2 V dc less
than input voltage, depending on load.
I/O POWER CONVERTER (OPTIONAL)
Input: 11 to 16 V dc, 15 mA with no load or shorted
output.
Output: 22 to 24 V dc, up to 0.6 A for transmitter
power.
