Terminals type B or U, as thermistor inputs:
Min. cross-sectional area................................0.75 mm² (19 AWG)
Max. cable length,
up to 75 °C (167 °F), cross-sectional area 0.75 mm² (19 AWG)
............................................................................75 m (250 ft.)
up to 75 °C (167 °F), cross-sectional area 1.5 mm² (16 AWG)
..........................................................................150 m (500 ft.)
up to 150 °C (302 °F), cross-sectional area 1.5 mm² (16 AWG)
............................................................................75 m (250 ft.)
Terminals type K (relay outputs):
Cross-sectional area.......................0.75 – 1.5 mm² (19 – 16 AWG)
Max. cable length ....................................................200 m (660 ft.)
Terminals type Y (for actuators powered via
the same transformer as the I/O module):
Min. cross-sectional area................................0.75 mm² (16 AWG)
Max. cable length
1
.....................................................20 m (66 ft.)
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 (22 AWG)
Max. cable length ....................................................200 m (660 ft.)

Some actuators allow greater cable lengths, for example:
EM52 0.5 mm² (20 AWG) 80 m (260 ft.)..three wires
EM15LBB 0.75 mm² (19 AWG) 80 m (260 ft.)..three wires
EM42 0.75 mm² (19 AWG) 80 m (260 ft.)..four wires
TAC Forta 0.75 mm² (19 AWG) 80 m (260 ft.)..four wires
TAC Forta 1.5 mm² (16 AWG) 100 m (330 ft.)..three wires(part nos. xxxx-010)
4.3 Commissioning
Commissioning of the I/O modules is normally carried out together with
the TAC Xenta controller units that they belong to.
The procedure is therefore described in the TAC Xenta 280 - 300 - 401
manual.
However, TAC Xenta 421A/422A and 451A/452A can also be used as
certified L
ONMARK® devices. When the open LonTalk® (SNVT) pro-
tocol is used, some additional configuration is required. This is
explained in the Configuration instructions
• 0FL-4181 for TAC Xenta 421A/422A and
• 0FL-4182 for TAC Xenta 451A/452A.
