The input and output are not insulated.
Limiters with bidirectional input and positive/negative bidirectional output can also be manufactured.
The manufacturable ranges for bidirectional output are ±50mV~±10V and ±0.1~±5mA.

Setting procedure
(Please carefully read the accompanying instruction manual.)
Lower limit
Upper limit
While measuring the lower-limit setting output voltage (between the LOW CAL. OUT and COM
terminals), vary the lower-limit setter (LO) to set the lower limit value.
While measuring the upper-limit setting output voltage (between the HIGH CAL. OUT and COM
terminals), vary the upper-limit setter (HI) to set the upper limit value.

Ordering method
Limiters restrict the variation range of an output signal and restrict the output to values
outside the preset limit range when a signal outside the limit range is input.
CAL signals proportional to setting values are output, allowing accurate settings and set
values to be checked.
Applications
Maximum and minimum value retention during abnormal operation of a control device
Prevent full opening/closing of devices such as control valves
Prevent of off-scale input to computers
