Sensor
See Guideline A in Table 3.INn
Binary Input - Dry Contact Maintained Mode
1 second minimum pulse width
Internal 12 V. 15k ohm pull up
See Guideline A in Table 3.
UNIVERSAL
(Inputs)
ICOMn
Universal Input Common for all Universal Input terminals
Note: All Universal ICOMn terminals share
a common, which is isolated from all other
commons.
Same as (Universal) INn
Binary Input - Dry Contact Maintained Mode
0.01 second minimum pulse width
Internal 18 V. 3k ohm pull up
INn
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
(Inputs)
ICOMn
Binary Input Common for all Binary Input (IN) terminals
Note: All Binary ICOMn terminals share a
common, which is isolated from all other
commons, except the Configurable Output
(CO) common (OCOMn) when the CO is
defined as an Analog Output.
See Guideline A in Table 3.
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.
See Guideline A in Table 3.
OUTn
Binary Output - 24 VAC Triac (External Power Source only)
Connects OUTn to OCOMn when activated.
External Power Source Requirements:
30 VAC maximum output voltage
0.5 A maximum output current
Maximum 6 cycles/hour with M9220BGx-3
40 mA minimum load current
See Guideline C in Table 3.
CONFIGURABLE
(Outputs)
OCOMn
Analog Output Signal Common All Configurable Outputs
(COs) defined as Analog Outputs (AOs) share a common,
which is isolated from all other commons except the Binary
Input common.
Binary Output Signal Common All Configurable Outputs
(COs) defined as Binary Outputs are isolated from all other
commons, including other CO commons.
Same as (Configurable) OUTn.
