Security Engineering SE 1110 OSDP I/O module

Eight relay outputs and eight digital inputs expand an OSDP controller, with a legacy Wiegand or Clock/Data reader interface.

Model / SKU: SE 1110
Category: Relays & Contactors
Product type: OSDP relay / I/O module
Role: Control interface

Control & power

Control type: OSDP over RS-485
Power supply: 12–30 V DC; 70 mA at 24 V with all relays on and no external load

OSDP over RS-485 from an access controller that supports this module and its input/output commands. Relay contacts switch an external circuit; they are not the module control input.

A suitable smart controller can expose supported functions to Matter. The control type alone does not confirm electrical compatibility or actual position feedback.
