9900 Transmitter
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.
Terminals 7-10: Digital (S
3
L)/Frequency Input
7: V+: +5 VDC out to sensor (black wire)
8: DATA: Input signal from sensor (red wire)
9: GND: Sensor ground (white wire)
10: SHLD: Cable shield
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
When connecting a non-Signet sensor to the 9900, the sensor’s 4 to 20 mA signal must be
converted to Digital (S
3
L). The 8058 i-Go Signal Converter accepts any 4 to 20 mA signal
and converts it into Digital (S
3
L).
1. Wire the 8058 between the 4 to 20 mA loop source and the 9900 Digital (S
3
L) input
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.
