Configuration
The 8130 RTU is supported by a full range of I/O interfaces. I/O expansion modules are available
for connection to almost every type of signal encountered in industrial environments. Since
wiring to field devices depends on the I/O expansion module, the procedure will vary for each
device. The basic 8130 RTU is constructed as a Motherboard with connectors for up to four I/O
expansion modules.
Note Refer to the 8130 RTU Installation chapter for guidelines and procedures for using
the 8130 RTU in a hazardous location.
Note The channel numbering will usually be the same regardless of the I/O expansion
board. Channel 1 begins with the top left connector and Channel 17 begins with the top
right connector.
The I/O modules are either single-sized (4.5" by 5.1") or double-sized (4.5" by 10.3"). The I/O
expansion modules are listed below:
• Model 8201 16-Channel Digital In-/Out module (contacts, relays)
• Model 8203 Dual RS-485 Communication Interface module (Modbus, MTS, PetroSense)
• Model 8204 8-Channel Multi-Function module (contacts, relays, Pulse Totalizer, Analog
inputs)
• Model 8205 16-Channel Analog Input module (4-20 mA, 1-5V)
• Model 8207 8-Channel Analog Output module (4-20 mA, 0-20 mA, 1-5V)
• Model 8208 TIWAY Interface module (Texas Instruments (IT-111, IT-121, IT-150)
• Model 8210 Varec Mark/Space Interface module (Mark/Space Micro 4-wire Model 1800,
Model 1900, Model 4000, 2900 FTT)
• Model 8211 Current Loop Interface module (Whessoe Bus Protocol, GPE Protocol)
• Model 8212 Saab TRL/2 Interface module
• Model 8213 V1 Interface module (Varec TGM 3000, TGM 4000, Varec SG6000)
• Model 8214 Enraf Interface module (Enraf 811, 802/812, 854, 873)
• Model 8215 L&J Tankway Interface module (MCG 1000, MCG 1500, MCG 2000)
• Model 8216 LON Interface module (Barton Instruments Series 3500)
• Model 8217 Dual RS-232 Interface module
Configuration instructions for each I/O expansion board can be found in the following relevant
chapters.
Motherboard Description
The motherboard description is broken into three sections. Each section identifies the location
