4.2.4 AC-2000 Plus Terminals
1.
Communications
: Three terminal blocks for PC communication using the optional
multiplexor,
MUX-2
.
o
RX (20)
: Receive into
AC-2000 PLUS
. With multiple controls, connect all the RX pins
together. Connect to TX at Multiplexor only.
o
TX (19)
: Transmit from
AC-2000 PLUS
With multiple controls, connect all the TX pins
together. Connect to RX only at Multiplexor only.
o
COM (18)
:
Ground reference for communications. Do not connect shields to this pin.
Connect to COM at multiplexor also.
2.
Relay Extension
:
Com (1)
- The relay extension box such as the
REB-8
may be located up
to 10 feet from the
AC-2000 PLUS
. Do not connect the shield to this terminal. Connect the
shield to earth ground only at one end of the cable to avoid ground loops.
o
Data (2)
: This line carries data to the relay extension.
o
Clk (3)
: This line carries a clocking signal for use by the relay extension.
3. Not used.
4.
6 Temperature Sensors (8, 9, 10, 25, 26, 27)
: The temperature sensor is a 2 wired black
shielded cable thermistor (RTS-2). Connect one wire to the temperature sensor terminal and
the other to common
(11, 28)
*Polarity does not matter.
5. Analog Inputs:
o
Humidity Sensor (30, 31, 32)
: Connect according to wire colors (White, Red, Black).
o
An.2
(13)
: Humidity Outside Humidity input. Connect the white wire of the Humidity sensor
to An.2 and the red and black together with the Humidity input red and black.
o
An.3
(14)
: Pressure sensor (C red wire to An.3 and Black – wire to Common).
6. Analog Outputs:
o
An.1 (33)
: 0 to 10V- Light Intensity control signal
o
An.2 (34)
: 0 to 10V- Variable speed control signal
o
COM (29)
:
Connect the common wire of An.1 & 2 to terminal 29
7. Digital Inputs:
o
Dig 1 (15)
: Feed overtime alarm input or wind direction selection
o
Dig 2 (16)
:
Feed counter
o
Dig 3 (17)
: Water meter
