1 Analog I/O Option MCB109
NB!
Please note the values available within the different standard groups of resistors:
1
E12: Closest standard value is 470Ω, creating an input of 449.9Ω and 8.997V.
E24: Closest standard value is 510Ω, creating an input of 486.4Ω and 9.728V.
E48: Closest standard value is 511Ω, creating an input of 487.3Ω and 9.746V.
E96: Closest standard value is 523Ω, creating an input of 498.2Ω and 9.964V.

Analog inputs - terminal X42/1-6

Parameter group for read out: 18-3*. See also
Parameter groups for set-up: 26-0*, 26-1*, 26-2* and 26-3*. See also

3 x Analog inputs

Used as
temperature
sensor input
Used as
voltage input
When used for voltage, analog inputs are scalable by parameters for each input.
When used for temperature sensor, analog inputs scaling is preset to necessary signal level for specified temperature span.
When analog inputs are used for temperature sensors, it is possible to read out feedback value in both °C and °F.
When operating with temperature sensors, maximum cable length to connect sensors is 80 m non-screened / non-twisted wires.

Analog outputs - terminal X42/7-12

Parameter group for read out and write: 18-3*. See also
Parameter groups for set-up: 26-4*, 26-5* and 26-6*. See also

3 x Analog outputs

Volt
Analog outputs are scalable by parameters for each output.
The function assigned is selectable via a parameter and have same options as for analog outputs on control card.

Real-time clock (RTC) with back-up

The data format of RTC includes year, month, date, hour, minutes and weekday.
Accuracy of clock is better than ± 20 ppm at 25 °C.
The built-in lithium back-up battery lasts on average for minimum 10 years, when frequency converter is operating at 40 °C ambient temperature. If
battery pack back-up fails, analog I/O option must be exchanged.
