This document describes how to mount and wire an FX-SC8XIOR16-0 (IOR-16) option module for
an FX80 controller. The IOR-16 is designed for the remote monitoring and control of applications
to facilitate end-to-end automation and device-to-enterprise integration. It expands an FX80
Supervisory Controller with 16 I/O points consisting of the following:
• Eight universal inputs (UI): Type 3 (10K) thermistors, 0-100kΩ, 0-10 VDC, 0-20 mA with external
resistor
• Four relay outputs (RO): Form A contacts, 24 VAC @ 0.5 A rated
• Four analog outputs (AO) (1-10 VDC)
The IO module uses DIN rail mounting and has two end-mounted five-pin connectors that support
direct-chaining to other IOR-16 modules or FX-SC8XIOR34-0 (IOR-34) modules. Communications
to an FX80 Controller use RS-485 multidrop on three wires of an end-mounted five-pin connector.
The other two wires on that connector are for INPUT power (15 VDC) and are supplied from a DIN-
mountable option (IOR-34) or a third party 13.5 VDC to 15.75 VDC power supply. The RS-485 bus is
wired back to COM1 or COM2 of the FX80 controller.
