DCP550 Programmer

DCP550 Programmer

The DCP550 series is a microprocessor-based 1/2 DIN controller programmer that combines superior functionality, quality and reliability.

The DCP551 single channel unit supports up to 99 program profiles with up to 99 segments per profile, while the DCP552 dual channel unit supports up to 49 dual program profiles with up to 99 segments per profile set. A universal input accepts thermocouple signals, resistance temperature detector (RTD) signals, DC voltages and DC currents. The DCP551 single channel programmer is available with one or two inputs and has one loop of control. The DCP552 is a dual channel programmer with two inputs and two loops of control. A carbon potential model is available on the DCP552. 

The DCP550 series supports extensive digital I/O functions including 16 digital inputs and 16 digital outputs. RS-485 ASCII communications and up to two auxiliary outputs can be added as options.



  • Programs/Segments: The DCP550 is capable of storing up to 99 programs with up to 99 segments per program with a maximum overall total of 2,000 segments and 4,000 events.
  • Universal Input: Accepts 37 different ranges of thermocouples, RTDs, current and volt linear inputs. All inputs are configurable as standard.
  • Universal Power Supply: The DCP550 can operate on any line voltage from 90 Vac to 264 Vac at 50/60 Hz continuously.
  • Control Outputs: Available with current, relay or logic outputs and configurable for PID A, PID B, PI, PD, or P+MR. An optional auxiliary 4-20 mA output can be used for heat-cool applications.
  • Event Strategy: Sixteen standard event open collector outputs are available for PV, deviation, controller mode or other state indications, as well as indication of time events and segment number events.
  • PV Start: This function offers the possibility to define setpoint values at the start of each program.  It could be either the current controller setpoint value (LSP) or the current process variable value (PV).
  • Digital Inputs: Sixteen dry contact inputs permit remote selection of program number, run, hold, reset, segment advance, fast forward, guaranteed soak reset, auto-tune initiation, manual control, PV channel selection.
  • Digital Outputs: Sixteen fully configurable open-collector digital outputs can be triggered by PV, SP, deviation, output, program status, auto-tune operation and diagnostic checks. An event code feature in additions can transmit program and segment number to an external PLC.
  • Memory Card: An optional memory card permits saving, retrieval and loading of up to 99 recipes and includes not only program but also associated event settings. Contactless technology guarantees trouble-free operation in harsh environments. The card is available in 8, 16 and 64K capacity. Full instrument configuration can also be saved on the memory card, but only one full configuration per card.
  • Communication: An optional RS-485 communications interface provides a link between up to 32 units and a host computer through Modbus RTU protocol at up to 9600 baud.
