TM-1400

MINI CONVERTER UNITOUTLINE
TM-1400 MINI CONVERTER UNIT is power supply and indication unit
which is used in combination with Tokyo Keiso’s TC-1000, TC-2000,
TC-3000, and EP-TC-1000/2000V series mass flow controllers.
All necessary functions of power supply to the mass flow controllers
and scaling indication of flow signal, and flow rate setting function
with the change of external/manual setting are provided in DIN 72mm
compact housing. Furthermore, it can be combined with IR4600
UNIVERSAL TOTALIZER with totalizing pulse output.
As described above, it is now easy to configure the flow-rate regulating sysytem for various gases.
Conventionally, each independent function is integrated, and spacesaving and simple installation work are attained.

Detector accuracy❏ Flow rate setting(1) External setting input signal
A mass flow controller is controlled by inputting voltage orcurrent signal into TM-1400 from external device.
(2) Manual setting
Switching and setting ratio of the input of setting from outside
are possible with the model with minimum memory 1% manual
setting function and 10 rotations analog dial vernier.
And it is also with a compulsive control selection capability
such as flow stop or full open.
❏ External setting input signal

CONBINATION WITH MASS FLOW CONTROLLER

When a model change is made from TM-7000 series toTM-1400 series using an existing mass ﬂow controller,a panel adapter case and an adapter cable are needed.
