46. Control Input Terminals
[CONTROL INPUT 1 – 16]
Photo coupler inputs. A current of approximately
2 mA flows when shorted, and the voltage
becomes under 40 V DC when opened.
The input of 100 msec or greater is required to
operate. These contact inputs can be isolated
from the SX-2100AI unit by cutting the power
feed jumper (45) and the isolation jumper (44).
Each contact input when isolated is 40 V DC
for maximum applied voltage and approximately
2 mA for the loop current. Since each terminal
is equipped with a current limiter employing
constant current circuitry, there is no need to limit
current on the external equipment side. The [–]
terminals of all control inputs are common. Use
the SX-2000 Setting Software to assign functions
to these terminals. (See the separate Setting
Software Instructions, "Event Settings.")
47. Analog Link Output Terminal
[ANALOG LINK OUT]
Connect this terminal to the analog link input
terminal of the SX-2000AI, SX-2100AI, SX-
2000AO, or SX-2100AO.
48. Analog Link Input Terminal
[ANALOG LINK IN]
Connect this terminal to the analog link output
terminal of the SX-2000SM, SX-2000AI, SX-
2100AI, SX-2000AO, or SX-2100AO.
49. SX Link Terminals [SX LINK A/B]
Use switching hubs to connect between the SX
link terminals of the SX-2000SM, SX-2000AI, SX-
2100AI, SX-2000AO, and SX-2100AO. Connect
each of the SX Links A and B to the same
switching hub*, or to different switching hubs* that
have been connected in star configuration.
Notes
• Be sure to connect both terminals of A and B.
• After connection completion, press the Reset
key to reactivate the SX-2100AI.
* Contact your TOA dealer for more information
on switching hubs.
