Calog Instruments (South Africa) – Calog Instruments has four new controllers on offer to the market, under the Calog brand. All feature an intuitive interface, with scrolling text prompts and up to 4 setpoints.

The Calog Quad Process Controller:
An advanced quad channel process controller with a virtually endless range of possible applications. Features include 4 process inputs (0/4-20mA) with optional channel averaging across 2, 3, or 4 input channels. The device supplies 24V excitation and is ideal for use in conjunction with a transmitter and it is easy to scale using low and high display values.

The Calog Quad RTD Controller:
An advanced quad channel RTD controller, ideal for numerous industrial temperature applications. Features include 4 RTD inputs (Pt100Ω, 385/392/Cn10); the ability to average the inputs across 2, 3, or 4 input channels, and use this averaged value for a display source or for setpoint activation; intuitive interface with scrolling text prompts; a choice of either C° or F° display.

The Calog Quad Thermocouple Controller:
An advanced quad channel thermocouple controller, ideal for numerous industrial temperature applications. Features include 4 thermocouple inputs (J/K/N/R/T type) and the ability to average the inputs across 2, 3, or 4 input channels, then use this averaged value for a display source or for setpoint activation. Also and intuitive interface with scrolling text prompts; and a choice of either C° or F° display.

The Calog Counter/Rate Batching Controller:
An advanced controller with 3 independent counters, ideal for rate monitoring and batching applications. Features include: 3 independent hardware counters; Quadrature (x1, x2, x4), NPN, PNP, TTL sensors and Intelligent count modes where users can choose from a variety of smart formulas to suit the application. Advanced features for this model are batching, batch count modification, programmable input functions, setpoint latching and startup inhibit.

Optional features on all of the models are the 4-20mA or 0-10V analog output, the RS232/RS485 serial port and data logging function.
