2 Usage The AI controller measures temperature and humidity; it also has an alarm capability if the measurement data exceeds defined setpoints. Historical measurement data can be displayed via only the G(B)-50A Web browser and TG-2000A. Temperature and humidity cannot be displayed on the G-50A LCD. Furthermore, an alarm can be output if measurement data exceeds a preset upper or lower limit. The AI controller also features a function that interlocks M-NET devices for indoor units, etc. set in

7-3. Connecting the Sensors • For channel 1, select one of the following four types: Pt100 detection, 4 to 20 mADC, 1 to 5 VDC, or 0 to 10 VDC analog input. • For channel 2, select one of the following three types: 4 to 20 mADC, 1 to 5 VDC, or 0 to 10 VDC analog input. • The wire length depends on the specifications of the sensor. However, since the use of long wires makes the device susceptible to noise, using wires shorter than 12 m (39.4 ft) is recommended. Use a shielded line for the senso

7-4. Connecting Alarm Setpoint Outputs (Non-valtage Contacts) The maximum wire length is 100 m. However, since the use of long wires makes the device susceptible to noise, using wires no more than 10 m long is recommended. To use these, various settings need to be configured. Refer to "8. Initial Settings". Load Caution: Power supply • To use X1 relay, obtain one that satisfies the following V1 (DC) specifications. Operating coil Power supply X1 Field [Applied load] V2 (DC) Connections MAX:
