FEATURE

• Latest Technology, Microcontroller based.
• Masterless 4-channel Plugin cards.
• LED windows with computer composed legends on photofilm.
• Works on any volts AC or DC. Plug-in type SMPS module.
• Jumper selectable alarm sequences, separately for every card.
• NO/NC input selectable by DIP switches on every card
• First - out group expansion
• Auxillary tripping contact
• Automatic sound cancellationBy adopting modular design combined with latest Microcontroller technology, 'Digilarm Series 1800' provides more features than any other system available. High noise immunity is provided at very low logic/LED power, hence ideally suited for all industrial environments. 4-Annunciation channels are mounted on one sequence card module for compactness and cost reduction.

  Input derived from 'dry' field contacts, the system is supplied either in Integral on Split architecture. The visual displays are available in any Rows x Column configuration of 6 or more windows. The integral unit and the windows cabinet in case of Split system are flush panel mounting type. Audible alarm device (Hooter/buzzer etc.) and Push Buttons are generally supplied 'loose' for separate mounting but can be provided on front of the Annunciation unit itself, if so required by the customer.

  Unsurpassed versatility of the 'Series - 1800' system permits field alteration of virtually every major aspect of Annunciators operation - Working voltage, NO/NC input Alarm Sequence, First-out groups, etc.

  Use of micro controller has greatly reduced the number of components, thereby enhancing reliability. No maintenance required. Not even lamps, Long life, super bright LED's have been used. No parts that could call for replacements.

• based on cmos ic technology
• high repeat accuracy
• exceptionally reliable & rugged
• low power consumption
• available in 4 - timing modes
• timing range available from sec. To hrs & days.
• rugged terminals & screws with high quality plating and grip washerapplication :'digidelay' series 2400/2000d timers are suitable in applications involving reliable and accurate timing such as in batch process, process control instrumentation, motor controls, sequence & interlock schemes, moulding & welding machines, machinetools, photographic and x-ray equipment etc.

  description :circuit scheme adopts technique of cmos ic based clock generation and counter. Two led indicators are provided on front face. One, to show 'power on' and the other, to show status of timer output relay. A knob is provided to preset the time with continuous setting.
