Binary Input - Dry Contact Maintained Mode
0.01 second minimum pulse width
Internal 18 V. 3k ohm pull up

BINARY
(Inputs)
Binary Input - Pulse Counter/Accumulator Mode
0.01 second minimum pulse width
(50 Hz at 50% duty cycle)
Internal 18 V. 3k ohm pull up
Binary Input Common
for all Binary Input (IN) terminals
Note:
All Binary ICOM
n
terminals share a common, which
is isolated from all other commons, except the
Configurable Output (CO) common (OCOM
n
) when
the CO is defined as an Analog Output.
ICOMn
See Guideline
C
in
Analog Output - Voltage Mode (0–10 VDC)
10 VDC maximum output voltage
10 mA maximum output current
Required an external load of 1,000 ohm or more.
Note:
The Analog Output (AO) operates in the Voltage
Mode when connected to devices with impedances
greater than 1,000 ohm. Devices that drop below
1,000 ohm may not operate as intended for Voltage
Mode applications.
OUTn
ANALOG
(Outputs)
Analog Output - Current Mode (4–20 mA)
Requires and external load between 0 and 300 ohm.
Note:
The Analog Output (AO) operates in the Current
Mode when connected to devices with impedances
less than 300 ohm. Devices with impedances
greater than 300 may not operate as intended for
Current Mode applications.
Analog Output Signal Common
for all Analog OUT
terminals.
Note:
All Analog Output Common terminals (OCOM
n
)
share a common, which is isolated from all other
commons.
