Rosslare R-805 Relay Output Expansion Board for AC-825IP Access Control Panel, 16 Form-C 5A Relays, RS-485 OSDP/RSDP-Bus

The Rosslare R-805 is a 16-output expansion board for the AC-825IP access control panel. It is designed for general-purpose and security applications where additional relay outputs are needed for door control, automation, signaling, or auxiliary device operation. Rosslare identifies the R-805 as the 16-output model in the R/S/D/P-805 expansion board family. This expansion board can be installed directly on top of the AC-825IP, mounted on a wall, or fitted on a DIN rail. It communicates with the AC-825IP through RS-485 using the OSDP/RSDP-Bus serial bus, helping expand output capacity while keeping the main controller architecture in place. The R-805 supports 16 Form-C relays with N.O., N.C., and COM contacts. Rosslare lists the relay output rating as 5A at 30 VDC or 5A at 30 VAC with 0.6 power factor, making it suitable for multiple access control and automation output functions. Electrical specifications include 12-16 VDC input power, 65 mA standby current at 12 VDC, 700 mA maximum input current excluding attached devices, and a 4-pin tamper connector from the enclosure. Rosslare lists the R-805 as indoor equipment with a 32°F to 122°F operating range and dimensions of 7.0 x 3.4 x 1.5 inches.
