Signal Type: 4 to 20 mA
When connecting a non-Signet sensor to the 9900, the sensor's 4 to 20 mA signal must be
converted to Digital (S
L). The 8058 i-Go Signal Converter accepts any 4 to 20 mA signal
3
and converts it into Digital (S
1.
Wire the 8058 between the 4 to 20 mA loop source and the 9900 Digital (S
terminals (see page 14).
2.
In the 9900 INPUT TYPE menu (see System Setup Menu discussion, page 25),
specify 4 to 20 mA INPUT.
3.
Set additional labels and abbreviations as described on pgs. 42-43.
Terminal Identifi cation
The 9900 requires regulated 10.8 to 35.2 VDC (24 VDC nominal)
from an external power supply (not supplied).
Maximum current draw is:
200 mA = 9900 without Relay module
300 mA = 9900 with Relay module
Terminals 1-2: DC Power
Required by the instrument
● 10.8 to 35.2 VDC input power to sensors, relays and the LCD backlight
Terminals 3-4: Loop Power (may also be used for system power)
● 10.8 to 35.2 VDC
NOTE: Backlight, LEDs and optional Relay Module do not operate on
loop power. Any connected sensors or sensor electronics that cannot
operate on loop power will also be inoperative.
Terminals 5-6: Open Collector
● Software selectable for Normally Open or Normally Closed.
● May be disabled (Off) if not used.
