Process Indicator Totalizer

DCY-2050 Universal Process Dual Loop Controller.
DCY-2051 Universal Process Dual Loop Controller.
DCY-2060 Universal Process Dual Loop Controller.
The design of DCY-2050, 2051 and 2060 Controllers is characterized by high reliability and precision, electrical noise and EMI immunity, besides well elaborated technical manual.
These features make them ideal for industrial applications in Instrumentation and Process Control.
They have an extruded aluminum case and use the best origin components and parts, proven by rigorous tests and specified according to the strictest worldwide norms. They offer two standard universal inputs that can be 4-20mA, 1-5Vdc, 0-10Vdc, 0-55mVdc, thermocouples and RTD; also standard is the 24Vdc power supply for two-wire transmitter. Two frequency inputs are available, in specific instrument, for signals up to 30kHz, from 300mVpp to 30Vpp and 70Vdc max. DIN 19234 compliance for intrinsically safe NAMUR sensors.

Process Dual Controllers

Model  Description 
DCY-2050  DCY-2050 Universal Process Dual Loop Controllers
DCY-2051  DCY-2051 Universal Process Dual Loop Controllers
DCY-2060  DCY-2060 Universal Process Dual Loop Controllers

Up to two analog output modules of 4-20mA, 1-5Vdc and 0-10Vdc, isolated from inputs and power supply.
Reduced dimensions, large control capacity performing the functions:
- Auto-tune.
- On-Off, P-PI-PD-PID and Cascade Control.
- Heating-cooling, time-proportioning.
- Remote set-point.
- Programmable set-point up to 10 segments.
- Auto-manual station.
Up to three SPDT and SPST relay alarm modules.
RS-232 or RS-422/485 communication.
Power supply from 90 to 240Vac, 50/60Hz or dc levels.
High accuracy.
Linearization of RTD, thermocouple and also square root extraction.
Configuration stored in non-volatile memory.

Power supply is universal and can be connected from 90 to 240Vac or dc levels when specified.
The controllers were projected on modularity and flexibility concepts.
The user can turn a single loop controller into a dual loop one, having a control output variety as relay, open collector, time proportioning, voltage 1-5Vdc and 0-10Vdc, current 4-20mA and dual (Heating-Cooling). They offer up to three alarm cards and a wide variety of controls: On-Off, PID and Cascade. The DCY controllers have two auto-tune algorithms: start-up or demand (controlled variable is far or near the set-point). Also they have all standard control features: bumpless auto-manual transference, output saturation, remote set-point, programmable set-point up to 10 segments, reset wind-up prevention.

Inputs:
Universal inputs models for thermocouple (J, K, T, E, R or S under ITS-90), 0-55mV, RTD under DIN 43760,
