WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
This product is not specically designed for use in hazardous environments, for example in explosive
atmospheres. If the product is to be used in hazardous environments we recommend that the user
ensures suitable protective measures are taken.
!
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
This module may contain hazardous voltages. Before removing the module from the rack remove all
supplies and disconnect user I/O signals.
Unused slots in the System 10/20 chassis are populated with blanking plates to prevent access
to user I/O signals that may be present. Blanking panels are available to order from Pickering in a
variety of slot widths. If the product is not used in this manner for example by using an extender card
then additional care must be taken to avoid contact with exposed signals.
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL
Certain semiconductor devices used in this equipment are liable to damage due to static voltage.
Observe the following precautions when handling these devices in their unterminated state, or
sub-assemblies containing these devices:
1. Persons removing sub-assemblies from equipment using these devices must be earthed by a
wrist strap and a resistor at the point provided on the equipment.
2. Soldering irons used during the repair operations must be low voltage types with earthed tips and
isolated from the mains voltage by a double insulated transformer.
3. Outer clothing worn must be unable to generate static charges.
4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in
anti-static bags.
CAUTION - PRODUCT DOCUMENTATION SYMBOL
Suitably qualied & trained users should ensure that the accompanying documentation is fully read
and understood before attempting to install or operate the product.
!
SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O
signals (refer to the Maintenance Section).
• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or
the combined weight of the modules & chassis.
• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the
chassis and the user I/O signals.
• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.

Diagram for the 20-410-041 Digital Input/Output
Module With 64-Bits of I/O
The 20-410 Digital Input/Output Modules offer a choice of port
congurations up to a maximum of 128-bits. Modules can be
specied as all inputs, all outputs or a combination of both.
All inputs are compatible with TTL voltage levels and are suitable
for receiving signals from logic circuits or sensors with TTL level
outputs. Outputs can be specied as either TTL, suitable for driving
standard logic, or Open-Collector, for driving higher current loads
such as relay coils. The Open-Collector option can tolerate up to
50V and sink up to 500mA of current.
The module is programmed by writing and reading data at bit, byte
or word level, this simplies the interfacing operation. Applications
include; generating control signals, stimulus and sensing status
from digital devices.
Typical Applications
• Construction of special one-off circuits
• Programmable ampliers
• Programmable attenuators
• Programmable lters
• Special circuits to drive external relays
• Mounting special relay types
• Dummy multiplexer channels for calibration purposes
