SIO Series
Modbus I/O modules The SIO series of remote I/O modules uses the Modbus protocol over an RS485 communications interface to allow it to be monitored and controlled from a central host. They are specially designed to be used in the harsh environment of energy management applications.
The SIO series has many models to choose from, each module having a different combination of DI, DO, AI and AO, each model designed based on practical use and actual need. They are ideal for use with energy or water meters, and the monitoring of transducer signals and on/off status of facility operations.
Each DO has a relay built in, and allows for the direct control of magnetic contactors. Each DI is optically isolated and is a dry contact input, which eliminates the need for an external power source.

AS Series Water Meters with Pulse Output
AS series water meters The AS series of water meters (from 1/2" to 4") are low cost and designed for residential, commercial or industrial sub metering applications. They are available in a variety of diameters for both hot or cold types. The pulse signal output of the water meter can be used with our AMR module for remote monitoring applications.

DFSR737A BTU Meter
BTU meter

The DFSR737A is a full featured and low cost BTU meter with Modbus over RS485 capability developed specifically for sub metering applications. The DFSR737A is unique among BTU meters by having the BTU calculator separate from the flow sensor, which allows the flow meter to be installed where it is needed, but with the BTU calculator and display installed anywhere it is convenient for tenant reading. The DFSR737A comes as a set together with the flow and temperature sensors.

AMR Auto Meter Reading Module PDF Print E-mail
AMR Module
AMR Module

The AMR (auto meter reading) is an I/O module that has been specifically designed for the special needs of auto meter reading applications. The AMR can be interfaced directly with the output of various types of pulse output meters (electricity, water, gas, BTU) and the data collected from the various meters sent to a central host via its RS485 interface. Some special features which distinguish it from regular I/O modules are:
- noise filtering from the pulse input to prevent miscounts
- EEPROM memory to retain count data in case of power interruption
- accommodates up to 16 channels of pulse input
- dry contact channel input that eliminates the need for additional power supply
- synchronize retain count with actual meter display
- rechargeable battery backup option to maintain at least 8 hours of continuous operation during a power outage
and many more!
