PD141 AFO
VIGILANTE^® ANNUNCIATOR

From urgent alarms to routine messages, the PD141AFO VIGILANTE® handles all types of operational messages with simplicity and economy. The VIGILANTE® delivers clear, eye catching (and ear catching) information to the plant operators. Alarm outputs from Precision Digital meters, alarm relays, logic levels from 5 to 28 VDC, and switches for parameters such as temperature, pressure, flow, level and proximity can all be fed directly into the VIGILANTE®.

NUMBER OF INPUTS
4 per VIGILANTE®; 8 per system

TYPE OF INPUTS
Momentary or maintained:

1. NO or NC switches: 
Each input circuit contains a pull-up resistor, so it
is not necessary to provide external excitation to the switch.

2. Open Collector Transistor: 
Open circuit voltage is approximately 5 VDC.

3. Logic Levels: 
LO = 0 to .8 VDC, HI = 4.7 to 28 VDC;
input impedance: 100 kilohms.

OPERATION
User field select: ISA Sequence A or ISA Sequence F2A (first-out)

TYPE OF OUTPUTS
Alarm condition indicated in three ways:

1. Relay:
1 SPDT relay (2 A@ 240 VAC) per PD141AFO. For fail-safe design, the relay is energized in the non-alarm state. In the case of a power failure, the relay will go to the alarm state (NC contact is connected to Common contact).

2. Audible:
Built-in horn

3. Visual:
Red LED next to the alarm message

ALARM MESSAGES
Custom printed free of charge. Area available per message is 1.25" x .28" (32 mm x 7 mm); user may specify any size and length that will fit in this area. Two lines of 14 characters each at 9 point type will fit.
