1.12.1.3. Discrete I/O
Discrete I/O interface options include both internal and remote I/O. A maximum of 12 inputs and 18
outputs can be supported through a total of three options (internal and external, combined).

1.12.1.4. IND560x-PAB
64061929 | 11 | 07/2017
When used with the ACM200 safe area communication module, this interface provides an
additional serial port (COM4 or COM5) at the same 300 meters (1000 ft.) distance from the
IND560x terminal.
This interface can also be used to operate an IND560x or IND226x terminal as a remote
display to the IND560x. The remote terminal can be located up to 300 meters (1000 ft.)
distance from the IND560x terminal.
The internal discrete I/O option is available in three different combinations of active/passive
inputs and active/passive outputs. Both the inputs and outputs use solid state devices.
─ Active inputs and active outputs: The inputs are powered internally by the IND560x terminal
and are designed for use with simple switches within the hazardous area. The inputs are
not approved for direct connection to devices in the safe area - a remote ARM100 should
be used for this. The outputs are also powered internally by the IND560x terminal and
provide 12V switching at 50mA total. These outputs are intended for use with extremely low
power intrinsically safe piezo electric solenoids.
Note: The Active/Active I/O option is not available for use with the IND560x-PAB and
external NiMH battery pack.
─ Active inputs and passive outputs: The inputs are powered internally by the IND560x
terminal and are designed for use with simple switches within the hazardous area. The
inputs are not approved for direct connection to devices in the safe area - a remote
ARM100 should be used for this. Power to operate the outputs must be provided by an
external power supply and intrinsically safe barrier. Refer to the approval entity values for
restrictions and limitations.
─ Passive inputs and passive outputs: Power to operate both the inputs and outputs must be
provided by an external power supply and intrinsically safe barrier.
Safe area remote I/O can be configured to communicate to an ARM100 device (refer to page 1-
20) using the ACM200 with the CL/RS-422/RS-485 option or the ACM500 configured with
Ethernet/COM2/COM3 option (refer to page 1-18 for additional details on the ACM500 and
page 1-20 for ACM200). One other possibility is to use COM1 on the IND560x main board.
This signal can be passed through an intrinsically safe barrier (ISB) and then through an RS-
232 to RS-485 converter, both located in the safe area. The ARM100 provides six dry-contact
outputs and four passive low voltage DC inputs. An external 12 - 24 volt DC supply is required
to operate the ARM100.
NOTE: The ARM100 is NOT approved for use inside hazardous classified areas. An ARM100
must be installed in the safe area only.
NOTE: Due to space limitations and battery life limitations, the IND560x-PAB (Power Adapter
Board) can only be used with the Harsh/Analog version of the IND560x. The IND560x-PAB will
not work with any panel mount or IDNet or SICSpro models of the IND560x. The IND560x-PAB
and external NiMH battery pack will also not support the Active-Active I/O option.
