Overall accuracy
Non-linear accuracy: ±1% of full scale within the range of PLC operation
temperature
Maximum deviation: ±1% of full scale at 20mA and +10V
Digital data format
2’s complement of 16-bit, 12 significant bits
Isolation method No Isolation between digital circuit and analog circuit
Protection
Voltage output has short circuit protection, but a long period of short
circuit may cause internal wire damage and open circuit of current
output.
#1: Detailed explanation of D1115: (Default is HFFFF, disable all channels)
Bit15~12(D/A) Bit11~8(A/D-Ch2) Bit7~4(A/D-Ch1) Bit3~0(A/D-Ch0)
D/A output mode A/D input mode A/D input mode A/D input mode
A/D input mode:
Value 0 1 2 3 4 5
Mode PT100(2wire) NI100(2wire) PT1000(2wire) NI1000(2wire) PT100(3wire) NI100(3wire)
Value 6 7 8 9 A B
Mode PT1000(3wire) NI1000(3wire) -10V ~ +10V -5V ~ +5V +1V ~ +5V -20mA~+20mA
Value C D E F
Mode 4mA ~ 20mA Reserved Disabled
D/A output mode:
Value 0 1 2 3~E F
Mode -10V ~ +10V 0mA ~ 20mA 4mA ~ 20mA Reserved Disabled
For example: Assume A/D-Ch0 is PT100(3wire), A/D-Ch1 is PT100(2wire), A/D-Ch2 is 4mA~20mA
and D/A is 4~20mA, then the D1115 will be set to H2C04.

Installation
Please install the PLC in an enclosure with
sufficient space around it to allow heat dissipation,
as shown in the figure.
y Direct Mounting: Please use M4 screw
according to the dimension of the product.
y DIN Rail Mounting: When mounting the PLC to
35mm DIN rail, be sure to use the retaining clip to stop any side-to-side movement o
the PLC and reduce the chance of wires being loose. The retaining clip is at the
