c.pCOe expansion card CAREL P+E0000000000: Basic version

P+E* is an expansion module developed for CAREL controllers applications. It provides significant flexibility, allowing optimum use of all its inputs and outputs. The universal inputs/outputs (marked as U in the connection diagram) can be configured in the application program on the controller that manage the expansion, to connect active and passive probes, digital inputs, analogue and PWM outputs. This allows additional input/output configurations, increasing the flexibility of the corresponding controller in different applications. The Enhanced version includes a driver for unipolar valve. For further information on the controller, see user manual “c.pCO sistema” (code +0300057EN).
