TAC Xenta 400 I/O modules

Terminals type X:
Min. cross-sectional area	0.25 mm²
Max. cable length	200 m

Terminals type U, connected as

a)digital inputs,

b)measurement devices using voltage signals that are not powered via the same transformer as the I/O module or

c)measurement devices using current signal

Min. cross-sectional area	0.25 mm²
Max. cable length	200 m

Terminals type U, connecting measurement devices, using voltage signals that are powered via the same transformer as the I/O

module:
Min. cross-sectional area	0.75 mm²
Max. cable length	20 m
Terminals type B or U, as thermistor inputs:
Min. cross-sectional area	0.75 mm²
Max. cable length,
up to 75 °C, cross-sectional area 0.75 mm²	75 m
up to 75 °C, cross-sectional area 1.5 mm²	150 m
up to 150 °C, cross-sectional area 1.5 mm²	75 m
Terminals type K (relay outputs):
Cross-sectional area	0.75 – 1.5 mm²
Max. cable length	200 m
Terminals type Y (for actuators powered via
the same transformer as the I/O module):
Min. cross-sectional area	0.75 mm²
Max. cable length 1	20 m
Terminals type Y (for actuators power supplied via
their own transformer, external or internal;
or when the outputs have isolated converters):
Min. cross-sectional area	0.25 mm²
Max. cable length	200 m

1Some actuators allow greater cable lengths, for example:

EM52	0.5 mm²	80m	threewires
EM15LBB	0.75 mm²	80m	threewires
EM42	0.75 mm²	80m	fourwires
TACForta	0.75 mm²	80m	fourwires
TACForta	1.5 mm²	100m	threewires (partnos.xxxx-010)

4.3 Commissioning

Commissioning of the I/O modules is always carried out together with the base units (TAC Xenta controllers) that they belong to.

The procedure is therefore described in the TAC Xenta 300 and 401 manuals.
