Toshiba AD268 Manuale Utente

User’s Manual   

(1) Use shielded twisted-pair cables for analog output signal lines and wire them in shortest

distance. Connect the cable shield to ground in shortest distance for EMC conformity.
Normally the grounding method (a) is recommended. However, depending on the condition,
method (b) or (c) may be useful for stable operation.

(2) Separate the analog signal cable from other cables to prevent noise interference. (200mm

or more)

(3) This module requires 24Vdc power. Apply the 24Vdc power before (or at the same time)

applying T2’s main power. Otherwise, this module detects the external 24Vdc error.

(4) If the external 24Vdc power for this module is not stable, the converted data will not be

stable. In this case, use a dedicated 24Vdc power supply for this module.

(5) When the external 24Vdc power is applied, about 0.7V voltage will output for few ms

(milliseconds). Therefore the power-up sequence should be as follows.
