Heater Break Alarm (option)
This function can be added if the instrument has an alarm option and the control output is the contact type or the SSR drive voltage type. In SR71,
addition is possible unless it has an SV bias option.

: Higher limit and lower limit absolute value alarms: Within full scale of measuring range
: Higher limit: 0~2000 unit
Lower limit: –1999~0 unit
In case SV is out of the measuring range, higher and lower limit values of the measuring range become the
action points.
: On-Off action
: Fixed to 0.2% of the measuring range
: Contact 1a (common)/240V AV 1.5A (resistive load)
: Heater amperage detected by externally attached CT. Alarm output
On upon detection of heater break while control output is On.
: Off, 0.1~50.0A (Alarm action stops when Off is set.)
: 0.1A
: 0.0~55.0A
: 5% FS (when sine wave is 50Hz)
: On time:500 msec.
: Selectable between Lock (holding) and Real (not holding)
: 2 sec.
: Insulated between CT input and control output (not isolated between CT input and system and other
inputs)
: –1999~2000 unit
: Same as display resolution
: Non-voltage contact (bias in action when SB terminal is closed)
: Insulated between the SV bias input and the control output (not isolated between the SV bias and the
system and other input)
: By non-volatile memory (EEPROM)
: –10~50˚C/90% RH max. (no dew condensation)
: 100-240V AC±10% (50/60 Hz)
: Approx. 11VA
: IEC1010-1
: EN50081-1
: EN50082-2
: Between input/output terminal and power supply terminal:
500V DC 20M Ω minimum
Between input/output terminal and protective conductor terminal:
500V DC 20M
Ω minimum
: 1 min. at 2300V AC between input/output terminal and power supply terminal
1 min. at 1500V AC between power supply terminal and protective conductor terminal
: Only front panel has simple dust-proof and drip-proof structure
: PPO resin molding (equivalent to UL94V-1)
: H48
