The signal Isolator Distributor Module model IS400P is an
auxiliary device projected to isolate galvanically a transmitted
signal (current or voltage) of a receiver device, typically a
register or controller. Besides, the power supply of the
module is isolated of the input and output.

The signal Isolator Distributor Module - IS400P - solves the
problem of the distortion in the signal transfer due to
potentials of different ground.

It can also be used in the power supply of transmitters to two
wires.

HOW TO CONFIGURE THE INPUTS AND
OUTPUTS OF THE CIRCUIT BOARD.

For inputs of 4-20 mA
Use the jumpers W2, W4 and W11.

For inputs of 1-5 Vdc
Use the jumpers W2, W4 and W10.

For transmitters to two wires
Use the jumpers W1, W3 and W11.

For outputs A 4-20 mA/output B 4-20mA
Use the jumpers W5 and W8

For outputs A 4-20 mA/output B 1-5 Vdc
Use the jumpers W6, W8 and W9

For outputs A 1-5 Vdc/output B 1-5 Vdc
Use the jumpers W6, W7e W9.

TECHNICAL SPECIFICATIONS:

n

  Power Supply: 24 Vdc ±10%

n

  Input:

 4-20 mA using the integral power supply for two-wire

transmitters.

 4-20 mA (for signal isolation)

 1-5 Vdc (for signal isolation)

Inputs for 0 to 20 mA and 0 to 5 Vdc can also be used, with
the outputs being respectively 0 to 20 mA and/or 0 to 5 Vdc.

n

  Integral Power Supply (when used).

  Maximum External Load: 300 (when used with 

LD250,

LD300, LD301, TT300

 and 

TT301

 Transmitters

Series).

  Short-Circuit Current: approximately 40 mA.

n

  Outputs A/B:

 4-20 mA/4-20 mA

 1-5 Vdc/4-20 mA

     

 1-5 Vdc/1-5 Vdc

     

 The output negative terminals are interconnected.

     

 Maximum load (current output): 750 

 with power supply

of 24 Vdc.

Observation:

In case of the outputs A or B is not used, it should be jumped,
or the other, the positive is to be conected to the negative.

     

 Minimum load (voltage output): 5 k 

.

n

  Accuracy: 0.15% of SPAN

n
