Outline of product

The temperature control block FX
or "FX -2LC") equipped with two temperature input points and two transistor (open collector)
2N
output points is a special block to read temperature signals from thermocouples and platinum
resistance thermometer bulbs, and perform PID output control.
Connect the FX
1) As input sensors, two thermocouples, two platinum resistance thermometer bulbs or one
thermocouple and one platinum resistance thermometer bulb are available.
2) Data can be written and read using FROM/TO instructions when the FX

have to create sequence programs for PID operation.)
3) Disconnection of heaters can be detected by current detection (CT).
4) The proportional band, the integral time and the derivative time can be easily set by auto
tuning.
5) Channels are isolated against each other.
