INSTALLATION INSTRUCTIONS INTERLOCK LOGIC BOARD (ILB)

PLEASE READ BEFORE INSTALLATION

MOUNTING THE INTERLOCK LOGIC BOARD

The Interlock Logic Board (ILB) can be mounted in any DynaLock Power Supply, using 6-#6-32 screws or the double-stick tape supplied.

WIRING THE INTERLOCK LOGIC BOARD

The ILB has 4 double-pole, double-throw relays that are field selectable for 12 or 24 volt DC operation. The relays are factory set for 12 VDC. To select 24 VDC operation cut the blue jumper located to the right of the relay. The relay contacts are rated 2 Amp @ 30 VDC. The current draw of each relay is 35 mA @ 12 or 24 volts.

The relay coils have a common negative input terminal. To energize individual relays apply a positive input voltage to the terminals marked +1, +2, +3 or +4.
