No. of outputs: 4
4 to 20 mA DC or 0 to 20 mA DC: I/O insulation type
Maximum load resistance: 900Ω
Transmission output range: Custom setting possible within measurement range
(Negative terminals of each transmission output channels are connected internally thus have the same electric potential.)

No. of outputs: 5
Alarm contact outputs: R1, R2, R3 and R4
Contact type: Relay contact, SPST
Contact rating: 240 V AC, 1A and 30 V DC, 1A (resistance load)
Contact function: Selectable from upper/lower limit operation (ON/OFF control), and delay operation
Contact action:

• Closed during control action (during error setting)
• Opened during normal status (including power supply off) 
  (R1 and R2, and R3 are for common use, respectively)

Error alarm output (RF)
Contact type: Relay contact, SPDT
Contact rating: 240 V AC, 1A and 30 V DC, 1A (resistance load)
Contact function: Selectable from error, trouble warning and maintenance
Contact action:

• When connected between C and NO, the contact is closed when status is normal and opened when error is detected (including power supply off)
  (Contact status is reversed for connection between C and NC.)

(R4 and RF are for common use)

No. of inputs: 1
Contact status: Open collector no-voltage contact a
Contact function: Transmission output hold

RS-485 input/output

Conductivity: Based on the specified compensation coefficient for the cell constant (parameter input)
Temperature: Calibrated by comparing with the reference thermometer

Selectable from the previous value hold and optional value hold (However, only the previous value hold is available during the maintenance mode.)

• Sensor diagnosis (Short-circuit and disconnection of the temperature sensor)
• Converter error

• Optional temperature compensation coefficient (reference temperature: 25ºC;
  temperature coefficient: 0 to 3%/ºC)

0 to 100ºC (For below 0ºC and above 100ºC, calculate accordingly)

Temperature: -5 to 45ºC, Relative humidity: 20 to 85% (without condensation)
