1A15, 1A16, 1A17, 1A21 Dual Analog
Input/output Module;
Analog Output:
The Analog Output is
a voltage only signal. 2-10 Vdc at
22mA
J2: 14 - 26 AWG with a maximum of
two 14 AWG
J2-1 Output #1 to J2-3 (Ground), J2-4
Output #2 to J2-6 (Ground).
UCP provides a 2-10 Vdc analog
signals as Outputs. The Output’s
maximum source capability is 22mA.
The maximum recommended length
to run this signal is included in the
table below.

Note: the above table is for copper conductors only.
Analog Input:
The analog input can be software
switched between a voltage input or
a current input. When used as a
current input a 200 Ohm load resistor
is switched in.
2-10 Vdc or 4-24 mA Analog Inputs
UCP accepts either a 2-10 Vdc or 4-20
analog input suitable for customer
external control. The type is
determined at unit commissioning
during feature installation.
J2: 14 - 26 AWG with a maximum of
two 14 AWG
J2-2 Input #1 to
J2-3 (Ground).
J2-5 Input #2 to
J2-6 (Ground).
Power, 24 +/- 10 percent VDC, 60 mA
maximum, Trane IPC3 protocol.
