controller. It assumes that you are an engineer,
technician, or service person who is performing access system design or installation.
Please read through this entire document before beginning the installation procedures.
These are the main topics included in this document:
This document does not discuss mounting and wiring of other components, or software configuration. For more

Product Description
The IO-16-485 expands a Vykon JACE
1
with 16 I/O points that can be remotely located, including
•
8 – universal inputs (UIs), compatible with 0–10Vdc, 4–20mA, dry contacts, pulsing dry contacts,
0–100K ohm resistive, or Type 3 thermistor temperature sensors.
•
4 – digital outputs with Form-A relay contacts, for on/off control of loads up to 24Vac/dc, at 0.5A max.
•
4 – 0–10Vdc analog outputs for analog control of loads at 2.5K ohm minimum, or 4mA drain maximum.
The IO-16-485 module uses DIN rail mounting, and has two end-mounted 6-pin connectors that support
direct-chaining (in-line attachment) to other IO-16-485 modules.
Communications to the remote JACE uses RS-485 multidrop on 3 wires of an end-mounted 6-pin connector.
The other 3 wires on that connector are primary DC power and battery backup for the module, which can be
supplied from that same JACE (such as a J-
x 02-XPR-24 or JACE-700). Alternatively, you can power the
IO-16-485 locally with a DIN-mountable NPB-PWR-UN universal AC power supply, or a third-party
12–15Vdc power supply, and wire only the RS-485 bus back to the parent JACE controller.
