The DRP-8500 Series modules offer a low cost analog I/O solution for micro PLCs. The series is ideal for discrete automation applications requiring one or two analog I/O channels. All models in the series interface with the PLC high speed counter inputs or pulse outputs. Digital signal pulse-width is fixed at 50 µsec. They will accept a variety of analog inputs, such as thermocouple, RTD, strain gage, voltage, and current. Some DRP-8500 models can be connected to pulse outputs from a PLC, and will then provide an analog output. The DRP-8500 series modules have an isolated floating optocoupler transistor which provides DC isolation from the input, output and DC power. The output transistor is fully floating allowing either source or sink connection to the PLC. The DRP-8500 resolution is 12 bits. The DRP-8600 Series modules are designed to interface with the low-speed 24 Vdc logic inputs of a PLC for applications requiring additional analog inputs. The DRP-8600 modules output a square wave up 500 Hz with a 50-50 duty cycle, allowing the PLC to count the frequency producing better than 8- bit resolution, 1 part in 500. The DRP-8600 module has an isolated floating optocoupler transistor which provides DC isolation from the input, output and DC power. The output transistor is fully floating allowing either source or sink connection to the PLC. All modules are housed in a plastic case with a built-in U-foot for mounting on standard DIN rails. Connections are made to screw clamp terminals that accept wire sizes 22 AWG to 16 AWG.

The DRF series DIN rail signal conditioners are designed to accept a broad range of input signals, such as ac and dc voltage and current, frequency, temperature (thermocouple and RTD), and process transducers, and provide standard process outputs of either 4 to 20 mA, or 0 to 10 Vdc. The DRF series feature a modern housing design, that is easily mounted on standard 35 mm DIN rails. Connections are safely and securely made through pluggable screw terminal connectors, with input and output connections on the opposite sides of the module.
The DRF-FR signal conditioner accepts a frequency input and provides an isolated 0 to 10 Vdc or 4 to 20 mA output. Models are available with three different power options, 24 Vdc, 120 Vac and 240 Vac.
The DRF-FR are ideally suited for industrial applications. All models mount on a standard 35mm DIN rail and provide galvanic isolation between input, output and power up to 3500 Veff . Module response time is 250 ms or less.

The FLSC-45 is a dc powered frequency-to-analog output signal conditioner with a 4 to 20 mA or 1 to 5 Vdc field selectable output. The high performance electronics will accept a low level magnetic pickup signal from a paddlewheel or turbine meter directly without amplification and convert it to an industry-standard analog output.

OMEGA^® high accuracy integral signal conditioners are designed for direct mounting onto OMEGA FTB-100 and 200 Series turbine meters. The input circuitry of the signal conditioners has been designed to receive and condition low level turbine meter signals while rejecting unwanted noise and spurious signals. A signal threshold control is provided which allows the user to set the input sensitivity above the ambient noise level, thereby eliminating any false signal on the output. Signal conditioners are available that can provide 4 to 20 mA, 0 to 5V, and scaled frequency pulse outputs that run on unregulated power supplies. Other units which run off 115 Vac provide both an unscaled pulse output and a 0 to 5V or 4 to 20 mA output. A zero and a span potentiometer allow for simple field adjustment of the analog outputs from the signal conditioners.
