We hold expertise in designing and developing Auto Manual Station (Model A881). These microprocessor based auto manual station are designed to control and display control parameters. The instrument work as an A/M Controller along with an indicator with retransmission output. Being an A/M controller, these instrument accept 4-20 mA input from sources like DCS and give output in normal auto mode. The control shifts from the AUTO mode to the MANUAL mode, during breakdown. User can now control the output 4-20 mA from the control keys provided on the front panel. This transfer is bump-less.
The controller continuous its control in auto mode, even in case of failure of A/M station. Furthermore, optional auto bias feature of these products allow even manual to auto transfer bump-less. To allow this bump-less transfer, the bias is set automatically in manual mode and then it can be converted by pushing buttons in auto mode. Along with this, external feedback signal o/p from the A/M station facilitate controller to track A/M output in manual mode. 1% and 10% per sec are the rates of change of output (in manual mode) and bias (in auto mode). The instrument is provided with 4 digit display which displays the output parameters as configured by the user.

Pantech's Alarm Annunciator, series 885, is an ideal instrument for indicating field fault conditions in the control room. It is designed to sense NO/NC potential free contacts for all the channels in a simultaneous mode. The high end microprocessor chips assures the response time in microseconds while sensing all the channels in round robin fashion. The audio and visual output is provided in the unit for alerting plant personnel when fault condition occurs. Controlling keys ACKNOWLEDGE, RESET and TEST are provided on the front of the instrument. For remote controlling of the unit, same keys can be provided on the back plate. Pattern of rows and columns change with change in total channels.

Features of Model 885:
  • Response time is very fast
  • Pertaining to high end microprocessor chip sets on board
  • First fault feature availed
  • Features like manual/auto reset, ring back, first up are provided as optional
  • Any no. of channels/windows possible (for more then 36 nos. Check with factory ends)
  • Enclosure/mountings/dimensions etc can be customized as per the user requirements
  • Weatherproof, flame proof, ip65 grade-all type of enclosures available

Prerequisite from the user:
  • Exact no. of windows and if possible window size
  • No. of rows and columns required by user
  • Dimensions of the instrument required
  • Input type – NO or NC
  • The modules incorporate low drift operational amplifiers and industrial grade components. Burn in of each module ensures a long trouble free operation
