Pulse Controller Converts Signals To Time-Proportional Output

The PCM5 series pulse-controller module converts a 4 mA to 20 mA signal from a process/temperature controller or computer to a time proportional output. The module mounts directly on a single 3- to 32-Vdc input SSR and supports single phase 50 Hz or 60 Hz operation. The CE compliant PCM5 tolerates inputs less than 4 mA. As an example, in a manufacturing environment, the PCM5 is used with a process controller and solid state relay to control electric heaters for oven drying manufactured parts. Price starts at $65.
