The JA PRO controllers are a series of single-display systems for rack mounting (96x96) with temperature measurement. The main operating modes are on/off, pulse proportional and PID. They can set and monitor: pH, ORP, chlorine (depending on the sensor: total chlorine, free chlorine, chlorine dioxide, hydrogen peroxide, ozone, bromine or paraacetic acid) and conductivity (uS/S - Ohm - TDS / PPM) with automatic range and sensor / product selection (H3PO4 - H2SO4 - HNO3 - HCl - NaOH - NaCl). Sensors are not included. The JA PRO has: 2 setpoints (on/off, proportional), flow alarm, backup flow sensor input, 0-20 mA or 4-20 mA output, proportional to the read value and programmable within the reading range, alarm output. Available with low voltage power supply 12 V or 24 V. Available with IP54 protection cover. JA PRO is equipped with mA module and MODBUS serial interface for connection to other devices on RS485 and TCP/IP MODBUS networks.
