SCR Power Controls

Opto Z provides precise proportional control of constant-resistance heating loads in response to an analog control signal from a temperature controller or PLC I/O module. The SCR power control utilizes an optically isolated trigger circuit for zero-fired switching. It regulates the amount of power applied over an adjustable time base for proportional control of the connected heating load. Zero-fired switching nearly eliminates electrical noise, and a full sine wave ensures harmonics-free output at all power levels.

Power Controller

EPower is designed to be flexible and efficient. A common driver module is used across the power controller range to minimize the need for spares and simplify setup and training. The single-driver module supports up to four power modules, resulting in the ability to support seven different load configurations. Connectivity with PLC, SCADA and DCS systems is straight forward with support for common industrial protocols such as Profibus, DeviceNet, Modbus TCP/IP and Modbus-RTU. Software flexibility is based on five attributes: the devices come preconfigured for out-of-the-box use via the order code; firing mode, current and voltage adjustments are straightforward; configurable I/O; input mode; and alarm setting.

Infrared Thermometer with Variable-Target Focusing

Marathon MM Series enables users to adjust the focus of measurement targets, either by push-button at the rear of the instrument, or remotely via an RS232/RS485 PC connection, where adjustments can be seen real-time through video. Users can select from either standard fixed-focus sensors or sensors with the variable-focus option, both with a focus range between 8" and 7' (200 mm and 2.2 m). Close-focus units also are available with fixed optics, enabling targets as small as 0.02" (0.5 mm) to be measured from a distance of 6" (150 mm). All of the infrared sensors provide integrated through-the-lens sighting, plus either laser or video-sighting for correct aiming and target location. The thermometer incorporates an optional live video feed into its data-acquisition and sensor programming software, allowing for active frame capture.
