An internal dry-contact relay DIO option is available with 5 inputs and 8 outputs. Each output
will switch up to 30 volts DC or 250 volts AC up to 1 amp of current. Voltages can be mixed
on this local discrete I/O option. The inputs are switch-selectable as either active (for simple
pushbutton control) or passive (for connection to PLCs or other devices that supply their own
power for the I/O). This option is not available for the IND570xx version.
Another internal dry-contact relay DIO/serial port option is available with 2 inputs, 5 outputs
and the COM2 and COM3 serial ports. Each output will switch up to 30 volts DC or 250 volts
AC up to 1 amp of current. Voltages can be mixed on this local discrete I/O option. The inputs
are switch-selectable as either active (for simple pushbutton control) or passive (for connection
to PLCs or other devices that supply their own power for the I/O). This option is not available for
the IND570xx version.
An internal solid state DIO option is available with 5 inputs and 8 outputs. Each output will
switch up to 30 volts up to 1 amp of current. Voltages can be mixed on this local discrete I/O
option. The inputs are switch-selectable as either active (for simple pushbutton control) or
passive (for connection to PLCs or other devices that supply their own power for the I/O).
Another internal solid state DIO/serial port option is available with 2 inputs, 5 outputs and the
COM2 and COM3 serial ports. Each output will switch up to 30 volts DC up to 1 amp of
current. Voltages can be mixed on this local discrete I/O option. The inputs are switch-
selectable as either active (for simple pushbutton control) or passive (for connection to PLCs or
other devices that supply their own power for the I/O).
Remote I/O function is supported by the ARM100 remote I/O module. ARM100 modules offer 4
inputs and 6 outputs. This module provides only dry-contact outputs. The ARM100's inputs are
passive. An external 10 to 32 VDC power supply is required to operate the ARM100. Either the
COM1 or COM3 serial port is required for communication with an ARM100 module. A
maximum of 3 ARM100 modules can be connected.
The COM3 serial port is available on the COM2/COM3 option or the COM2/COM3/DIO
combination option.
A maximum of 17 inputs and 26 outputs are supported (5 Inputs/8 Outputs local I/O option,
and three ARM100 remote I/O modules).
THE INTERNAL DISCRETE I/O RELAY OPTION #30113540, OR #30113542 MUST NOT BE
USED IN AN IND570xx TERMINAL. FAILURE TO COMPLY WITH THIS WARNING COULD
RESULT IN BODILY HARM AND/OR PROPERTY DAMAGE.
