Dual display process controllers

1 July 2015 Enclosures, Racks, Cabinets & Panel Products

Instrotech is offering three new dual display controllers under the Calog brand.

The DUAL-CTR is a counter/rate batching controller with three independent counters with quadrature (x1, x2, x4), NPN, PNP, TTL sensors which make it ideal for rate monitoring and batching applications. It has intelligent count modes where users can choose from a variety of smart formulas to suit the application, and dual display for simultaneous viewing of multiple variables.

Advanced features for this model are batching, batch count modification, programmable input functions, setpoint latching and startup inhibit. Also featured is an intuitive interface with scrolling text prompts and up to four setpoints. Optional features are the 4 – 20 mA or 0 – 10 V analog output and RS-232/RS-485 serial port.

The DUAL-DEW humidity/temperature controller, designed for wet and dry bulb, relative humidity applications, features dual 4 – 20 mA analog outputs plus dual display for temperature and relative humidity. Features include dual 3-wire RTD input (385/392, Pt100); dual display or simultaneous viewing of humidity and temperature; and an intuitive interface with scrolling text prompts. The unit is factory calibrated for 385 RTD – simple recalibration using high and low input signals. Also, it offers two isolated 4 – 20 mA analog outputs for humidity and temperature, up to four setpoints and an RS-232/RS-485 serial port.

The DUAL-FLO is an advanced flow batching totaliser and controller which accepts a variety of flow sensor inputs and is compatible with a variety of flow sensors (NPN, PNP, TTL namur, tacho or closed contact). The unit has a single totaliser with flow batching and features easy sensor calibration using direct K factor entry or pulses per unit of measurement. Advanced features include volumetric pulse, latching, startup inhibit and inflight adjustment. Also featured are up to six setpoints (one for batching) and optional 4 – 20 mA or 0 – 10 V analog output, and RS-232/RS-485 serial port.
