DI and PI Modules (ROC800-Series)
 |
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.
