Smart Multi-channel Temperature Controller/ Monitor with 4-20mA output MS151 - MS151

Multi-channel Temperature Controller (LED display) MS151

Performance

• Multi-channel input,single 4 to20 mA analog output
• Only 8 V voltage drop within whole loop circuit
• Galvanic isolation from input to output
• The highest temperature for output displaying
• Fault signal on sensor break circuit
• High accuracy in total ambient temperature range
• Explosion-proof-Certification
• IP66(aluminum alloy casing)
• Digital display (LED)
• Anti-RFI-Certification(especially for intercom)

Field of application

• MS151Series multi-channel temperature monitor is mainly used in the applications of
  multi-point temperature measurement or alarm warning system. By adopting SMT technology,it offers excellent accuracy, reliability and anti-disturbance .
• Input type : Pt100,Cu50(TC if specially required)
• Measuring Points : 4,6 points
• Temperature at any measuring point can be displayed by operating the keys on panel,The corresponding indicator light above the key is on at the same time.
• Hint signal for sensor fault can be sent out in the form of high alarm or low alarm.
