Relay contact output 5 SPST relay contact outputs
Relay contact capacity: 220 V AC/2A (resistive load)
Isolated with relay between contacts, and between contacts and internal circuit.
Max. 5 functions can be selected among those listed below.
① Zero-side solenoid valve drive output for automatic calibration
② Span-side solenoid valve drive output for automatic calibration
③ Suction pump OFF output in automatic calibration
④ Upper limit (1 point) concentration alarm output
⑤ Lower limit (1 point) concentration alarm output
⑥ Upper/lower limit (1point) concentration alarm output
⑦ Upper limit (1 point) and lower limit (1 point) concentration alarm output (Total 2 points)
⑧ 2-step upper limit (1 point at each step) concentration alarm output (Total 2 points)
⑨ 2-step lower limit (1 point at each step) concentration alarm output (Total 2 points)
⑩ Analyzer error or automatic calibration error alarm output
⑪ Calibrating status output
⑫ Range identification output (for 2 range type only) 
Contact input 3 non-voltage contact inputs ON: 0 V, OFF: 5V DC, current at ON: 5mA Isolated with photo coupler between inputs and internal circuit. Not isolated between contact inputs. The following actions are available: 
① Remote holding of measured value output ② Remote range changeover (only with 2-range analyzer) ③ Remote start of automatic calibration 
Interference gas measured value input 1–5 V DC analog input for H2 analyzer interference correction
Either CO2 or CH4 value measured by an external gas analyzer 
Adjustment at Fuji Electric factory is required. We will check the details of the gas to be measured when receiving an order.
Auto calibration Zero and span calibrations are automatically carried out at the predetermined intervals. Externally installed solenoid valves are driven to flow calibration gas sequentially.
Communication RS-232C (9-pin D-sub output)
Half duplex, asynchronous
MODBUS protocol, communication speed 9600 bps
Contents of communication: Reading/writing of measured concentration values and various set values, and output of device status
