• Twelve inputs (DI1 – DI12)
• R
i
= 10K ohm
• Max. 20 Hz input frequency
• Switching conditions: OFF: U

i
≥ 5 V
• Protected switching up to 40 Vdc / 24 Vac
• LED per channel, color selectable in two groups (SW1: DI
1 – 6; SW2 DI: 7 – 12); color combinations: see Table 7
• 18 Vdc auxiliary voltage supply (unregulated)
• 1 sec polling time with CPU

ONWORKS status LED
(L2)
• Dimensions (WxLxH): 47x97x70 mm
The digital input module has twelve input channels which can
be used for connecting sensors or any device providing a
digital output. The input values are read by the CPU and can
then be used for monitoring or as parameters for controlling
other devices
The unit plugs into the XSL513 Terminal Block and can be
inserted and removed without disturbing other units on the
bus. Terminals DI1 through DI12 are the digital inputs and
terminals 13 through 17 are wired together and provide an
auxiliary voltage of 18 Vdc. The module address is set using
the rotary HEX switch.
Beginning with V2.04.00 Excel 500 controller firmware, the
online point attribute Normally Open / Normally Closed
(NO/NC) defines the relation between the physical state
(contact position) and its logical status. See Table 7.

Figure 6. LONMARK Object for each digital input.
For each Sensor Object, the XFL523 Digital Input Module
provides an additional output NV, SNVT_switch. For an open
L
ONMARK integration, this offers a more convenient way of
accessing the sensor value compared to using the NV
SNVT_count. If the Sensor Object is configured as
“Totalizer”, this NV is invalid (switch.state = 0xFF,
switch.value = 0).
