Binary Input - Dry Contact
Maintained Mode
0.01 second min. pulse width.
Internal 17 V, 3k Ohms pull up.
BI-#
Binary Input - Pulse Counter/
Accumulator Mode
0.01 second min. pulse width.
(50 Hz at 50% duty cycle).
Internal 17 V, 3k Ohms pull up.
BINARY
(Inputs)
BI-C#
Binary Input Common
for all
Binary Input terminals
See Guideline A in Table 7.
Analog Output - Voltage Mode
(0–10 VDC)
10 VDC maximum output
voltage.
10 mA maximum output current.
Requires an external load of
1,000 Ohms or more.
Note:
The AO operates
in Voltage Mode when
connected to devices
with impedances greater
than 1,000 Ohms. Devices
that drop below 1,000
Ohms may not operate as
intended for Voltage Mode
applications.
See Guideline C in Table 7.
AO-#
Analog Output - Current Mode
(4–20 mA)
Requires an external load
between 0–300 Ohms.
Note:
The AO operates
in Current Mode when
connected to devices with
impedances less than 300
Ohms. Devices that exceed
Ohm may not operate as
intended for Current Mode
applications.
See Guideline B in Table 7.
ANALOG
(Outputs)
AO-C#
Analog Output Signal Common
for all Analog OUT terminals
Note:
All Analog AO-C#
terminals share a common,
which is isolated from all
other commons.
Same as (Analog) AO-#.
