INSTALLATION INSTRUCTIONS

GENERAL INFORMATION

In addition to the four fast digital inputs and four relays (two normally open, two changeover) present in every Excel Smart I/O, specific models are equipped as follows:

Removable Terminals (XFC1Dxx), 110 Vac (long housing)

•XFC1D06001: four universal inputs (NTC20k), two 0...10 V analog outputs, built-in transformer, six manual overrides, ten status LEDs

Removable Terminals (XFC2Dxx), 230 Vac (long housing)

•XFC2D05001: two universal inputs (PT1000, Ni1000, or Ni1000TK5000), two 0...10 V analog outputs, built-in transformer, six manual overrides, ten status LEDs

•XFC2D06001: four NTC20k universal inputs, two 0...10 V analog outputs, built-in transformer, six manual overrides, ten status LEDs

Removable Terminals (XFC3Dxx), 24 Vac (short housing)

•XFC3D04001: two universal inputs for three-wire PT100 sensors, two 0...20 mA analog outputs, six manual overrides, ten status LEDs

•XFC3D05001: two universal inputs (PT1000, Ni1000, or Ni1000TK5000), two 0...10 V analog outputs, six manual overrides, ten status LEDs

•XFC3D06001: four NTC20k universal inputs, two 0...10 V analog outputs, six manual overrides, ten status LEDs

Fixed Terminals (XFC1Axx), 110 Vac (long housing)

•XFC1A06001: four universal inputs (NTC20k), two 0...10 V analog outputs, built-in transformer

Fixed Terminals (XFC2Axx), 230 Vac (long housing)

•XFC2A05001: two universal inputs (PT1000, Ni1000, or Ni1000TK5000), two 0...10 V analog outputs, built-in transformer

•XFC2A06001: four NTC20k universal inputs, two 0...10 V analog outputs, built-in transformer

Fixed Terminals (XFC3Axx), 24 Vac (short housing)

•XFC3A04001: two universal inputs for three-wire PT100 sensors, two 0...20 mA analog outputs, short housing

•XFC3A05001: two universal inputs (PT1000, Ni1000, or Ni1000TK5000), two 0...10 V analog outputs

•XFC3A06001: four NTC20k universal inputs, two 0...10 V analog outputs

The term "universal inputs" refers to analog inputs for tem- perature-sensor signals which can be configured as voltagevariable or slow digital inputs (e.g. for dry-contact / opencollector signals). In the case of the XFC3A04001 and XFC3D04001, reconfiguration of the two 3-wire PT100 universal inputs yields four voltage-variable or slow digital inputs.

Further, the universal inputs and the analog outputs each feature an extra 24 Vac power output terminal capable of powering field devices.

BEFORE INSTALLATION

IMPORTANT

It is recommended that the Excel Smart I/O be kept at room temperature for at least 24 h before applying power to allow the evaporation of any condensation resulting from low shipping / storage temperatures.

CAUTION

To avoid electrical shock or equipment damage, you must turn OFF the power supply before attaching / removing connections to/from any terminals.

INSTALLATION

Mounting

The Excel Smart I/O is available with either

•short (W x L x H = 126 x 76 x 110 mm) or

•long (W x L x H = 180 x 76 x 110 mm)

housings (see Fig. 1) conforming to IP20/30. The mounting procedures are similar for both sizes.

The Excel Smart I/O is suitable for mounting on both a standard rail (DIN EN 50022-35 x 7,5) for installation in wiring cabinets or fuse boxes, and on walls/ceilings.

DIN Rail Mounting/Dismounting

The unit can be mounted onto the DIN rail simply by snapping it into place. It is dismounted by gently pulling the stirrup located in the base of the housing (see Fig. 2).

When mounted on a DIN rail, the unit must be secured in place with a stopper to prevent sliding.

Wall/Ceiling Mounting/Dismounting

The unit can be mounted on walls or ceilings in any orientation desired. In the case of ceiling mounting, however, it should not be operated at ambient temperatures exceeding 45 °C. The unit is mounted by inserting 3.5-mm dowel screws through the corresponding screwing noses.

After mounting the Excel Smart I/O, provide for cable access by snipping out the terminal protection covers' cut-out tabs and snap (by hand) the covers (available in packs of 8) into place onto the housing. To remove a cover, place a screwdriver in the leverage slot (see Fig. 10) and pry it loose.

Power Supply

General Information

All module inputs and outputs are protected against overvoltages of max. 40 Vdc and 24 Vac.

NOTE: Local wiring guidelines (e.g. VDE 0100) may take precedence over recommendations provided in these installation instructions.

NOTE: To comply with CE requirements, devices with a voltage in the range of 50 to 1000 Vac or 75 to 1500 Vdc lacking a supply cord, a plug, or other means for disconnection from the power supply having a contact separation of at least 3 mm at all poles must have the means for disconnection incorporated in the fixed wiring.

Models equipped with a built-in transformer are powered with either:

•230 Vac (-15%/+10%), 50 or 60 Hz (XFC2xx) or

•110 Vac (-15%/+10%), 50 or 60 Hz (XFC1xx)

When not supplying external devices with 24 Vac, these models have a power consumption of under 17.5 VA.

Models with a short housing are powered with 24 Vac (±20%), 50 or 60 Hz from an external transformer (which can power more than a single Excel Smart I/O; in this case, it is essential that the different Excel Smart I/O's not be connected with each other in any additional fashion, e.g. by being grounded, or by being connected to the same field devices). The 24 V models have a power consumption of under 6.5 VA.

Each universal input and each analog output features a

24 Vac power output terminal capable of supplying power to field devices. If the module is supplied with direct current, these power output terminals will deliver only direct current.

NOTE: The max. combined current draw of all of the field devices supplied by the power output terminals of a single Excel Smart I/O equipped with a built-in transformer must not exceed 300 mA (cos φ = 1) for prolonged periods of time. In the case of an Excel Smart I/O powered by an external transformer, the max. combined current draw is 500 mA (cos φ = 1). Disregarding these limits can result in the destruction of the built-in / external transformer.

Connecting to the Power Supply

The Excel Smart I/O is connected to the power supply as shown in Fig. 4 or Fig. 5, as the case may be.

All wiring must comply with applicable electrical codes and ordinances. Refer to job or manufacturers’ drawings for details. Use a min. of 18 AWG (1.0 mm2) and a max. of 14 AWG (2.5 mm2) for all power wiring.

Do not reverse the polarity of the power connection cables. Also, avoid ground loops (i.e. do not connect one field device to several Excel Smart I/O modules): Failure to observe these instructions may result in short circuits, damaging your devices.

In the case of models with removable terminals, an orangecolored T terminal plug may be used. In this case, the T terminal plug is plugged into pins 1 and 2 (24 Vac models) or pins 43 and 44 (110 Vac and 230 Vac models).

If power is supplied via T terminal plugs, it is possible to disconnect individual Excel Smart I/O modules from the power supply without disturbing the operation of other devices powered by the same source.
