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

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 that exceed below 300 ohm 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.

Binary Output - 24 VAC Triac
(External Power Source)
Connects OUT
n
to OCOM
n
when activated.
External Power Source Requirements:
30 VAC maximum output voltage
0.5 A maximum output current
1.3 A at 25% duty cycle
40 mA minimum load current

Binary Output Common
(for OUT

terminal)
Note:
Each Binary Output Common terminal (OCOM
n
) is
isolated from
all
other commons, including other Binary
Output Common terminals.
