Transducers
Filters
A ripple (AC component) of approximately 5% P-P is contained in the output of K Series
models. Use this filter if the ripple is to be reduced to 1% P-P or less.

Input and output
*1 The H Series and S Series transducers do not require the use of T-51FA because the output ripple is 1% P-P or less.
*2 T-51FA is not necessary when a transducer and an indicator (Mitsubishi Electric L or Y models) are used in combination.

Warning
The internal resistance of T-51FA is approximately 160Ω. Please note that problems such as the examples listed below may
occur.
Example 1: Combination with a K Series transducer (current output)
Example 2: Combination with an H Series or S Series transducer (current output)
Example 3: Combination with a voltage output transducer
In the case shown to the left, the total load resistance
connected to the output of the K Series transducer is
5.16kΩ (5kΩ+160Ω) and the output thus becomes
smaller than the normal value.
In the case shown to the left, the total load resistance
connected to the output is 660Ω (500Ω+160Ω) and
exceeds the allowable limit. For an output of 4~20mA,
a load in the range of 0 to 440Ω can be connected to
an H Series or S Series transducer.
In the case shown to the left, the output of the H
Series or S Series transducer is divided between the
160Ω and 10kΩ resistances, and thus the output
becomes less than the normal value. The same
phenomenon may also occur with a K Series
transducer.
