TAC Xenta 400 I/O modules
4 Installation
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
1
Some actuators allow greater cable lengths, for example:
EM52
0.5 mm²
80 m
three wires
EM15LBB
0.75 mm²
80 m
three wires
EM42
0.75 mm²
80 m
four wires
TAC Forta
0.75 mm²
80 m
four wires
TAC Forta
1.5 mm²
100 m
three wires
(part nos. 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.
