Analog Inputs
e 1353 has four or six 0 – 15 V analog inputs, depending on the model. ese inputs are scaled
down by 5.76, clamped to 3.3 V, and read by a 12-bit ADC internal to the MCU.

* Can be used as serial port on 1353-4101 and -6101.
e maximum resistive input on each analog input is 7.5 kΩ. e resistive or voltage type of analog
input can be selected by a Curtis programmer (1313/1314) or CAN SDO message.
ese six analog inputs can also be used as digital inputs. A unique feature of these digital inputs is
that the active high/low thresholds are completely programmable. us, these inputs can be used
with analog sensors to detect conditions like over/under pressure, high/low level points, etc.
Encoder Inputs
Analog Inputs 1 – 4 can be congured as two encoder inputs (Encoder 1A&1B and Encoder 2A&2B).
ese standard quadrature encoder inputs accept open collector encoders with pull-up resistors. e
encoders can be powered from the +5V supply (Pin 3) or the +12V supply (Pin 10) while using the
I/O GND as a common.
