14.02-18
Note 1.
Using this configuration, up to four 2100-A
16
s
can be connected using Clock/Reset mode,
or 2 using Binary Channel Selection mode,
provided the open collector outputs can
handle the load.
Note 2.
Each Digital input draws 8mA at 20Vdc.
Note 3.
All cables must be screened, and the screens
earthed at one end only.
Note 4.
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 1.
In this configuration the 2100-A
16
DI COM and
Digital inputs are isolated from the 2100-A
16
inputs and outputs. The 24V external power
supply can therefore be used to power
transmitters connected to the 2100-A
16
inputs.
Note 2.
There is no limit to the number of 2100-A
16
s
that can be connected, except the power supply
and open collector outputs must be able to
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

Important:
Do not use the 2100-A
