CPC400

The Watlow CPC400 controllersprovide performance and flexibility in a compact design and integrate full-featured closed-loop control with user-written logic. Programmable logic can interact with closed-loop control and operate I/O independently.Four and eight loop versions offercomplete control solutions for a broad range of applications. TheCPC400 supports thermocouples,RTDs, linear voltage, current and frequency. Built-in diagnostics automatically detect sensor failures including open, shorted and reversed conditions. I/O can also be utilized for closed-loop control, alarms and user programs. Using the built-in communicationsport, system designers can interface one or more controllers to a host computer for operator controls and data acquisition. The CPC400 offers PID, cascade, ratio and differential control strategies. Process variable retransmit and remote analog set point can be used to integrate the CPC400 with other devices such as chart recorders.The CPC400 carries the CE markand is UL Programmable Logic •40ppm/°C •Programming languages: LadderLogic, Sequential Function Chart, Function Block Diagram•Memory: 64k flash (nonvolatile)•Logic programs run concurrentlywith closed loop control •Read/write access: controller I/Oand closed loop control parameters Temperature Coefficient •120dB at 60Hz Flexible, easy-to-use interfaces Noise Rejection •Easy setup with menu guided, full-text prompts•Context-sensitive, on-screen helpsaves time•WATVIEW software minimizessetup time •Integrate with other serial devicesusing Modbus™•Connect to system components viaanalog I/O to retransmit process variables and read set points
