Product catalog summary
Specifications:
  • Temperature Input Group: Supports various thermocouples (K, J, E, T, R, S, B, N) and RTDs (Pt100, JPt100) using a 3-wire system.
  • Voltage/Current Input Group: Accepts voltage inputs from 0 to 10V DC and current inputs from 0 to 20mA, with a 250Ω shunt resistor needed for current inputs.
  • Input Characteristics: Features a sampling time of 0.25 seconds, with performance influenced by external and lead resistance.
  • Display: Utilizes an 11-segment LCD for process value (PV) and a 7-segment for set value (SV), with a temperature range display from -1999 to +9999°C.
Performance:
  • Insulation and Dielectric Voltage: Provides more than 20MΩ insulation resistance and a dielectric voltage of 1000V AC for 1 minute.
  • Measuring Accuracy: Accuracy varies by input type and temperature range, with limitations below certain temperatures.
Control Methods:
  • PID Control: Features autotuning with options for P, PI, PD, and ON/OFF control, and selectable direct/reverse action.
  • Heat/Cool PID Control: Offers startup tuning conditions with fine-tuning settings from -3 to +3.
Output Specifications:
  • Control Output Types: Includes relay contact, voltage pulse, current output, SSR (Triac), and voltage output, each with specific load resistance requirements.
  • Analog Retransmission Output: Provides 4 to 20mA DC and voltage outputs with high resolution.

RB Series Process and Temperature Controllers-2

The RB Series has very short depth. The series was designed with a mounting bracket that allows close horizontal mounting of as many as six units. So bright and so large it is easy to read (sv) from a greater distance. RB400 PV display CB400 PV display (Actual size) In the factory default state, only one set value, SV1, can be stored. (It is possible to change to a 4-SV specification.) Numerous inputs and outputs RS-485 (ANSI/MODBUS protocol) • The number of digital outputs is limited depending on the model and specifications. •An analog output cannot be added to some control types and models. •...

Save space and save money with a new series that gives outstanding control capability and comprehensive functions incorporated into a slim body case. _ Calculates optimum PID values to stabilize control _ A . B faster than ever B Sampling 0.25sec The improved autotuning algorithm calculates optimum PID values that shortens the time to reach stable control at the set value as well as eliminating overshoot/undershoot. The new PID algorithm also suppress overshoot/undershoot against external disturbance. The RB high performance controller provides precise control by sampling every 0.25 seconds....
