Note 1.
This configuration reverses the logic so when
the PLC digital output is off, the 2100-A
16
is on.
Note 2.
With 1k resistor, up to four 2100-A
16
can be
connected in this configuration, provided the
open collector outputs can handle the load.
Note 3.
Each digital input draws 10mA at 24Vdc.
Note 4.
All cables must be screened, and the screens
earthed at one end only.
Note 5.
For Clock/Reset Channel Selection DO NOT
connect PLC outputs 3 and 4 to DI 3 and DI 4
of the 2100-A
16
.
Important:
Do not use the 2100-A
16
power supply to
power up any transmitter or other equipment. An external
power supply must be used for this purpose. The 20V
supply is for the 2100A
16
Digital Inputs/Outputs only.
* For PLC RTX, CLOCK & RESET Channel Selection
refer to Section D, Mode 3.
* For PLC RTX, Bin Channel Selection refer to Section
D, Mode 4.

Note 2.
For Clock/Reset Channel Selection the
resistors = 1k . Up to four 2100-A
16
can be
connected in this configuration provided the
open collectors can handle the load. For
Binary Channel Selection the resistor =
2.2k . Up to two 2100-A

can be connected
in this configuration provided the open
collectors can handle the load.
