Control System
Components
1A15, 1A16, 1A17, 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).
CH530 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.
0-12 Vdc or 0-24 mA Analog Inputs
CH530 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
