Sensor error detection Input Types Otder Than B: A Sensor error is detected and tde Sensor Error Flag is turned ON if tde upper or lower limit of tde set input range is exceeded by 20°C or 20°F. The process value overrange direction when a Sensor error occurs can be specified (high: set input range +20°C or +20°F, low: set input range -20°C or -20°F). B Input Type: A Sensor error is detected and tde Sensor Error Flag is turned ON if tde upper limit of 1,820°C or 3,220°F or tde lower limit of 0°C or 0°F is exceeded. The process value overrange direction when a Sensor error occurs can be specified (high: set input range 1,820°C or 3,220°F, low: set input range 0°C or 0°F).
Function Process value alarm Process value 2-point alarm (HH, H, LL, L), alarm hysteresis, and ON-delay timer (0 to 60 s) are available. External alarm outputs: One per input (H or L).
External alarm outputs NPN outputs (witd short-circuit protection) External power supply voltage: 20.4 to 26.4 V DC Max. switching capacity: 100 mA (for one output) Leakage current: 0.3 mA max. Residual voltage: 3 V max.
Isolation Between inputs and Controller signal: Transformer for power supply and photocoupler for signals Between each input: Transformer for power supply and photocoupler for signals.
