Series SCD-8 can be used to control up to eight independent PID control circuits. The base unit has four thermocouple or RTD input channels, and additional input cards can be purchased if needed. If more than eight loops are required or to mix input channel types, the company’s slave modules can be added without wiring additional power or communications cables. Each loop can be programmed through the standard RS485 serial communications or an optional plug in LED display module.
