Semaphore DI-5-I Remote Terminal Unit Control Module

Semaphore DI-5-I is a 16-channel digital input module designed for the Kingfisher RTU family, bridging external DC signals to the remote terminal unit. Each channel accepts DC digital inputs and feeds the RTU processor, enabling reliable monitoring of binary field devices such as switches, sensors, and contact closures, with the RTU storing the input points in its configuration data. The DI-5-I is integrated with the Kingfisher backplane architecture and is typically used in SCADA installations to provide discrete input status for alarms, events, and automation logic, with status LEDs on the module indicating active inputs. This module is part of Semaphore's Kingfisher Plus+ remote terminal unit ecosystem and supports standard digital input behavior within the DI-5 family, offering a compact, 16-channel solution for expanding I/O without altering the central processor performance.
