The Rosslare PS-C25TB-U is a power management enclosure with a built-in secure relay I/O module for Rosslare AYC convertible reader systems. Rosslare describes the PS-C25TB as a factory-preassembled combination of the ME-0515M power management enclosure and the MD-25TB secure relay I/O module. This unit is designed to help convert Rosslare AYC convertible readers into secure standalone controller units. The MD-25TB secure module isolates the lock from the outside controller unit, helping protect lock functionality if the outdoor reader/controller is tampered with. For power management, the PS-C25TB supports 110-240 VAC, 50/60 Hz input and provides 15 VDC, 4A output to the PM-05 power management module. The PM-05 provides two independent 14.5 VDC, 2A power channels with isolated self-resetting fuse protection. The secure relay module includes lock and auxiliary Form-C SPDT relay outputs rated up to 5A, plus built-in speaker support for bell, chime, and siren functions. Rosslare lists the operating environment as indoor and the enclosure dimensions as 9.0 x 8.8 x 3.3 inches.
