Dual Trip Alarm or Alarm Monitor

The Dual Trip Alarm or Alarm Monitor allows you to monitor 0-20mA and 4-20mA analog signals or 0-5V analog signals. Alarm 1 has 10 different modes of operation. Alarm 2 has 9 different modes of operation.

The Dual Alarm monitor is easily configured by a PC program via its serial port. All alarm parameters are stored into the non volatile EEPROM memory.
Configurations can be saved to your hard drive on your PC.

• High Level Alarm. A relay is switched on when the analog input level remains above a specified High Level. Relay is switched off on returning to Low Level
• High Level Alarm Latched. A relay is latched on when the analog input level remains above a specified High Level. Relay is switched off on returning to Low Level and closing Reset input
• High Level Alarm Timer. A relay is switched on for a time when the analog input level remains above a specified High Level.
• Low Level Alarm. A relay is switched on when the analog input level remains below a specified Low Level. Relay is switched off on returning to High Level
• Low Level Alarm Latched. A relay is latched on when the analog input level remains below a specified High Level. Relay is switched off on returning to High Level and closing Reset input
• Low Level Alarm Timer. A relay is switched on for a time when the analog input level remains below a specified Low Level.
• High Low Level Alarm. A relay is switched on when the analog input level remains above a specified High Level or below a specified Low Level.
• High Level Alarm Latched. A relay is latched on when the analog input level remains above a specified High Level or below a specified Low Level.
• High Level Alarm Timer. A relay is switched on for a time when the analog input level remains above a specified High Level or below a specified Low Level.
• Analog Input Compare. A relay is switched on for a time when the level at analog input 1 is greater than analog input 2.
  

Other Features include

• All external connections are via screw terminals.
• Analog inputs are 10 bit (0.5% accuracy)
• Relays can switch 3A @240VAC

USES
Apart from generating an alarm when a high or low level is exceeded, the uses of the Dual Analog Alarm Monitor are countless. Some examples are
Switch on and off a pump based on the level in a tank or well
Control pressure using ON-OFF control of a compressor
Switch on and off an air conditioner, based on output of a temperature transducer
Switch on and off an oven, based on output of a temperatre transducer
Control Chemical Dosing using ON-OFF control

For configuration all you need is our free software and a standard D9 Male to D9 Female RS232 cable. The Dual Analog Alarm Monitor can be purchased in a DIN rail mount for easy mounting on DIN rail
