| Contact output |
Number of relay : 5
- ALARM or ERROR contact R1, R2 and R3
- Contact type: relay contact, SPST(1a)
- Contact rating: 240VAC,3A (resistance load)
- Contact function: Upper or lower ON/OFF alarm on each measurement items, conductivity, concentration, temperature, including delay time and hysteresis.
- Contact action: Closed when status or error is in the event. Opened when status is normal or power is down.
- ALARM or ERROR contact R4
- Contact type: relay contact, SPDT(1c)
- Contact rating: 240VAC,3A (resistance load)
- Contact function: Upper or lower ON/OFF alarm on each measurement items, conductivity, concentration, temperature, including delay time and hysteresis.
- Contact action: Closed when status or error is in the event, opened when status is normal or power is down for C-NO output. C-NC output is opposite action of C-NO.
