The following is a list of available SMART I/O MODULES that are used in conjunction with the 608C Controller to make up a 608C Networked Facility RTU.

SDAM 8 Channel Analog Input Module
PDAM 8 Channel Analog Input Expansion Module
SDIM 8 Channel Low Speed Accumulator Module
STRB 4 Channel Turbine Meter Accumulator Module
SDAO 2 Channel Analog Output Module
SDIO 48 Digital Input / 48 Digital Output Module

The SDIO is interfaced to Field Wiring with Automation & Electronics, Inc. DIF-8 and DIF-16 Digital Input Modules, and PRO-4 and PRO-8 Relay Output Modules.

Each of these smart modules interface to the main 608C control processor via RS-485 serial communications using the Modbus Protocol.

A 608C Facility RTU can handle up to 48 Gas Meter Runs and additional Turbine Meter Inputs, actuate Relay Outputs, etcetera. Automation & Electronics, Inc. has supplied many Facility RTU applications over the years. Applications included replacements for existing Hydril Facility RTUs and HP Facility RTUs. Our Facility RTUs are cost effective solutions compared to PLCs.
