Remote Input and Output (RIO) Module Specifications

General Specification	Range & Features
Interface to Guidance Controller
Communications Interface	Interfaces via 10/100 Mbps Ethernet. Can be located anywhere within the local network of the Guidance Controller.
Communications Protocol	Supports the MODBUS/TCP communications protocol. Uses a variation of this protocol to interface to Guidance Controllers. Protocol is compatible with all standard Ethernet TCP/IP networks. Can be configured as a slave to standard MODBUS/TCP masters (cannot communicate with Guidance Controllers in this mode).
Scanning Rate	Scanning rate for changes in inputs configurable. New input data sent to controller when values changed. New output data received from controller when values changed. Typical scanning rates are 5-10msec.
Number of units	Up to 4 RIOs can be simultaneously interfaced to a Guidance Controller.
Input and Output Interfaces
Ethernet Port	Standard and Enhanced RIO: One 10/100 Mbps Ethernet port
Serial Ports	Standard RIO: One RS-232 port with hardware flow control
Serial Ports	Enhanced RIO: Two RS-232 ports with hardware flow control, one RS-422/485 port
Digital Input Channels	Standard RIO, Enhanced RIO: 32 optically isolated digital inputs Configurable in banks of 8 as sinking or sourcing 5VDC to 24VDC for logic high if sinking 24VDC supplied for logic high if sourcing
Digital Output Channels	Standard RIO, Enhanced RIO: 32 optically isolated digital outputs Sinking outputs is standard. Sourcing are a special order item. 24VDC maximum pull up if sinking 24VDC supplied if sourcing, 100mA maximum per channel
Analog I/O Channels	Standard RIO: None
Analog I/O Channels	Enhanced RIO: 4 analog input channels, +/-10VDC, 12 bit ADC
General
Size and Weight	75mm (W) x 195mm (L) x 28mm (H), 0.142 kg
Low Voltage Logic Power	24VDC required for logic and input/output functions: Standard RIO: 0.4A minimum for logic plus 3.2A maximum if sourcing all digital outputs for a total of 3.6A. Enhanced RIO: 0.4A minimum for logic plus 3.2A maximum if sourcing all digital outputs for a total of 3.6A.
Special Order Options	Both the Enhanced RIO and sourcing output signals are special order items. As such, the lead time for these options can be quite long and minimum order quantity requirements apply.
