This document covers the mounting and wiring of the IO-R-34 module
for expanding an EC-BOS-8. It assumes that you are an engineer,
technician, or service person who is performing control system design
or installation. Please read through this entire document before
beginning the installation procedures.
Product Description
The IO-R-34 expands an EC-BOS-8
remotely located, including:
16 Universal Inputs (UIs) compatible with 0-10Vdc, 0-20mA, dry
•
contacts, pulsing dry contacts, 0-100K ohm resistive, or Type 3 thermistor temperature sensors.
10 Digital Outputs (DOs) with Form-A relay contacts for on/off control of loads up to 24Vac/dc, at 0.5A max.
•
8 Analog Outputs (AOs) for 0-10Vdc analog control of loads at 2.5K ohm minimum, or 4mA drain maximum.
•
The IO module uses DIN rail mounting and has two end-mounted 5-pin connectors that support direct-chaining
(in-line attachment) to IO-R-16 modules.
Communications to an EC-BOS-8 uses RS-485 multidrop on 3 wires of an end-mounted 5-pin connector. The other
two wires are for OUTPUT power (15 Vdc) used to power IO-R-16 modules. The IO-R-34 can provide power to up
to 4 attached IO-R-16 modules (if used). A two position connector is provided for primary power input to the module.
The RS-485 bus is wired back to Com 1 or Com 2 of the EC-BOS-8.
Related Documentation
For more information on mounting, wiring and configuring a system, refer to the EC-BOS-8 Mounting & Wiring
Guide, Remote IO-R-16 Mounting and Wiring Guide, and the NRIO Driver Guide.
System Planning
System planning requires consideration of options regarding power, RS-485 communications, mounting and wiring.
The following sections describe communications and power variables to consider before mounting and wiring your
hardware.
Number of Supported Expansion Modules
An EC-BOS-8 can support a maximum of 8 IO-R-34 modules OR a maximum of 16 IO-R-16 modules on a single
RS-485 bus. So, the IO-R-34 counts as two IO-R-16 modules. For example, the EC-BOS-8 could support 2 IO-R-34
modules and 12 IO-R-16 modules.

  • Page 2 Option 9 IO-R-34 Both IO-R-16 and IO-R-34 should have a UPS power backup if continuous operation during power failures is a requirement. These modules do not support the battery powered configurations provided on some legacy hardware. The 5 pin power/comm connectors do not include a battery pin, preventing connection to (and possible damage from) legacy controllers.
