Before and after the power supply and power entry module View 1) Power OK LED 2) low-voltage DC power input module 3) high voltage DC power input module 4) low-voltage AC power input module 5) high-voltage AC power input module relay module provides four relay 13500/32 extend a DPDT relay extension cable, configuration can be triggered after alarm state 3500 according to the monitor module. Configuration software allows for various combinations of alarm Bentley extension cable programming, ranging from a warning or danger state single channel to two or more channels will combine to provide a particular state AND (and) or OR (or) voting complex Boolean logic. By increasing the number of relay modules can provide contacts for each channel independently, global alarm notification alarm type and channel group. 3500/34 TMR Relay Module with a special TMR Rack Interface Module and three monitor module work together to provide the input signal 2 out of 3 vote. Relays are epoxy sealed and has interrupters installed as a standard form. Relays can be programmed as normally open or normally closed operation. In addition to any alarm frame relay, also provides a common system OK Relay 2. The relay is located in Bentley RIM front, coupled to the frame for all modules OK circuit. These circuits monitor the operational status of each module. When the module and its associated sensors or sensor field wiring any fault, OK relay will notice that it is a single-pole double-throw (SPDT) type, usually charged to provide additional notification when the main power fails.
