Automatic control unit JA

remoteTCP/IPconductivity

JA CONTROL INSTRUMENT JA control instruments are a series of rack mounting (96x96) single reading systems with temperature reading, mA module and native modbus (JA PRO). On/Off, impulsive proportional and PID are the main working modes. It can set and monitor: pH, ORP, chlorine, total chlorine, free chlorine, chlorine dioxide, hydrogen peroxide, ozone, bromine or paracetic acid (depending on the probe) and conductivity with automatic range and select probe / product (Ohm - H3PO4 - H2SO4 - HNO3 - HCl - NaOH - NaCl - TDS / PPM) for best results. Probes are not included. JA models have: 2 setpoints (on/off, proportional), flow alarm, flow sensor stand-by input, 0-20 mA or 4-20 mA output proportional to read value and programmable in the reading range, alarm output. Avalilable low voltage 9-18VDC or 18-36VDC power supply and IP54 protection cover. JA PRO version is equipped with mA module and MODBUS serial communication to be connected to other devices on RS485 networks and TCP/IP MODBUS. FEATURES 2 On-Off/proportional setpoints Flow alarm Remote control for flow sensor Remote control for flow sensor 0-20 mA or 4-20 mA output proportional to read measured value and programmable in the reading range Temperature compensation with NTC sensor
