Transmission output | Number of output points: 4 4 mA to 20 mA DC: input/output isolated type Maximum load resistance: 900 Ω Transmission output range: Freely selectable within the measurement range (Negative terminals of each transmission output channel are connected inside and thus have the same electric potential.) For Cur4, the transmission output can be changed by external input. | |||
Contact output | Number of outputs points: 5 Alarm contact output (R1 to R4) Contact type: Relay contact, SPST (1a) Contact capacity: 240 V AC, 1 A and 30 V DC, 1 A (resistance load) Contact function: Selectable from the upper/lower limit action (ON/OFF control), delay, and hysteresis Contact action: closed during control operation (error setting), opened normally and while the power is down (However, R1 and R2, R3 share the COMMON contacts respectively.) Anomaly alarm output (RF) Contact type: Relay contact, SPDT (1c) Capacity: 240 V AC, 1 A and 30 V DC, 1 A (resistance load) Contact function: Selectable from error, anomaly alarm, and maintenance. Contact action: When the C-NO contact is used, it is closed during the normal operation or opened when an error occurs (including the case where the power is turned OFF). (The C-NC contact acts inversely to the C-NO contact.) (However, R4 and RF share the COMMON contacts respectively.) | |||
Contact input | Number of input points: 2 Contact status: Type-A contact with open collector being of no-voltage Contact functions: Transmission output range selection and external input for Hold (Select either “Transmission 4 range selected” or “Transmission 2 range selected + Hold”) | |||
Communication output | The RS-485 input/output | |||
Calibration function | Conductivity: Based on the specified compensation coefficient for the cell constant (parameter input) Temperature: Calibrated by comparing with the reference thermometer | |||
Transmission output hold feature | Selectable from the Previous value hold and the Optional value hold (however, only the previous value hold is available in the maintenance mode.) | |||
Self-diagnosis function |
