Control cabinet of batching tank SA-259
Control cabinet of doubled batching tank SA-259-02

 
 

Control cabinets SA-259 and SA-259-02 are designed to monitor volume of the foam former and control during the process of its operation in automatic firefighting system.

Functions

  • reception and processing of impulse signals from flow rate sensor (for SA-259-02 from two flow rate sensors), analog signal (4-20mA) from pressure sensor (for SA-259-02 from two pressure sensors), reception of input digital signals
  • delivery of digital control signals according to specified algorithms
  • automatic control, indication and signaling of ultimate values, level of foam former
  • measurement, computation, indication and delivery in the telecontrol system of actual , cumulative and increasing value parameter
  • adjustment of system time
  • diagnostics and indication of equipment operability
  • system information protection from illegal access using passwords and lock words
  • information transfer in the telecontrol system via interface RS-485 as per protocol MODBUS RTU
  • memorization of accounting parameters values in controller at electrical power failure
