The economical, multi-function RLP logic circuit can be used as a DPDT latching alarm relay, or provide a relay for two-door interlocks (mantrap), or can initiate a brief signal delay to eliminate timing problems among multiple monitoring points on a door under access control. Provides additional relay to access control systems requiring N/O or N/C dry status signals. Provides a brief delay to harmonize door state reporting from multiple detection points. Can create a relay interlock circuit. Use with locks to create an interlocked trap entry. Provides DPDT relay with 1A contacts.
Provides time delay of door operator when electric lock is used.
