Overview

DI-24 is Suprema's multi-door RS-485 interface module, enabling direct connection of up to four Wiegand or RS-485 OSDP readers to CoreStation over a single RS-485 bus. With three RS-485 channels, four relay outputs and six supervised inputs, DI-24 expands CoreStation's door coverage while maintaining encrypted OSDP V2 communication throughout the access control system. Rated IP65 with a 1.2 GHz processor, 4 GB Flash and 256 MB RAM, DI-24 is designed for demanding enterprise and industrial deployments where reliable, large-scale multi-door control is required.

Key Features

3-channel RS-485 interface

Three independent RS-485 OSDP V2 channels connect readers, input modules and output modules — all managed through CoreStation.

4 relay outputs

Four independently controlled relay outputs for electric strikes, mag-locks and auxiliary devices — one per door.

6 supervised inputs

6 supervised input channels plus 3 AUX inputs (AC power fail, tamper, fire) — complete door-state and alarm monitoring.

IP65 rated

Dust-tight and water-resistant housing with Wiegand 2-channel input — integrates legacy readers alongside OSDP readers.
