调度员与警报单元的选择

controllers with module alarm option 1)modular alarm 2)2 alarm outputs 3)full autotune PID control 4)Build-in ExcitationFEATURES: 1.Designed for light industrial machinery, oven, laboratory equipment, refrigeration / heating equipment, temperature range between 0 999 °C. Easy to operate and learn, low price, with delayed output function, which to protect compressor. 2.Build-in SSR or relay contact output, it’s unnecessary to install output modules. optional relay module L1 or L5 for 1 2 way alarm. 3.Universal 100 240VAC power supply. 4.Using auto-tuning (AT) function and AI Artificial Intelligence algorithm, the internal computing accuracy is 0.1 °C. High control accuracy and no overshoot. 5.Passed CE certification, excellent quality, safety and s trong resistance to interference Models TREX-CB700 External dimension W*H*D/(mm) 72X72 X 90 Perforate dimension W*H(mm) 68X 68 Display units Three digits LED twin display, display range 0.0 999 Scale 0 - 999°C(software free setting) Control precision Accuracy: 0.3 grade; Control deflection: ±1 digit Input signals(available) Thermocouple: K,E,J,N ; Thermo-resistance: Pt100; Control mode PID ; P, P+D, P+I ; ON/OFF control (Hysteresis error could be set) Main output M: Relay contacts(250V/3A); V: SSR5V/30mA Control effect F: PID reverse adjust (for heating) D:PID positive adjust(for refrigeration) Alarm channels Could supply 1 2 alarm channel(s) Alarm types N: no alarm ; A: lower deviation alarm; B: higher deviation alarm; H: higher limit alarm; L: lower limit alarm; Power supply Universal AC 85 265V (50/60Hz) SMPS or DC 24V Power dissipation ≤2W Work condition Temperature: -10 50°C ; Humidity: ≤85% no caustic or magnetic field interference Alarm output modules available : Module type Photo Module name Description Relay module L2 Relay normally-open and normally-close contact switch output module (capacitance: DC30V/2A, AC250V/2A, normal type) L5 Dual normally-open contact switch output module (capacitance: DC30V/2A, AC250V/2A, suitable for alarm)
