24. Appendix
24.1 Connection of the external analog box
The analog box is connected to the RS232C interface of the
Phoenix circulator with the enclosed interface cable.
You activate the analog input in the „Settings“/„ Interfaces“
menu.
The power supply of the analog box is done via the marked
connection clips.
For this a direct voltage between 9V and 36V is required.
Attention: The power supply (mains transformer or
similar) is not included in the delivery.
24.2 Pin assignment
Attention: The pin 087--1336 for the I/O port is not
included in the delivery.
24.2.1 Signal input
For signal input the socket has the following pin assignment:
4 = reference input + (set value),
6 = reference input -- (set value).
Working resistance for current input: < 150
Ω
,
Input impedance for voltage input: > 50 k
Ω
.
24.2.2 Signal output
For signal output the socket has the following pin assign-
ment:
2 = measuring value + (actual value),
3 = measuring value -- (actual value).
Working resistance for current input: < 500
Ω
,
Output impedance for voltage input: > 10 k
Ω
.
For the operation of the circulator with an analog low voltage
normal signal via the I/O port you can choose between
1)
voltage input,
2)
voltage output,
3)
current input and
4)
current output.
I.e. with this interface you can
•
define set values (voltage and current input) and simul-
taneously
