Suitable for multi-point measurement, alarm, collecting ◆ aluminum alloy, imported high-quality terminals ◆ anti-jamming design, inhibit the rapid burst interference relays, contactors, and so on-site generation and other electromagnetic interference, immunity to all three ◆ input channel with a surge, overvoltage protection ◆ This product is fully functional standard, except 4:00 public alarm, but can be connected with a large-screen display ◆ two parameters, the first two configuration parameters is password control, with parameter copy feature to quickly set parameters, reduce the size of the workload parameters ◆ unique and practical alarm function for each channel can be set two alarm value, the alarm mode is selected as the upper or lower limits, you can achieve, the upper, upper and lower limits lower and lower limit function, independent alarm sensitivity setting 2:00 Common relay outputs, 2 relay mode mode can be set 1 RL1: when any passage from the non-alarm state to alarm state action, automatic delay recovery or panel key recovery RL2: As long as there is a channel that is in alarm state operation mode 2 RL1: As long as there is a channel of the first alarm in the alarm state, that action RL2: As long as there is a channel of the second alarm in the alarm state, that action ◆ independent alarm indication for each channel light, off, flashing, bright 3 state, no light means no alarm, blinking into the alarm, press the mute button to turn light ◆ computer can read a specified one or more channels or all channels via a communication interface data, greatly reducing communication time ◆ input circuit with protection, improve the reliability and anti-jamming capability ◆ Enter 5 to 80 channels, RTD, thermocouple, current, voltage input ◆ basic error of ± 0.2% F · S, the display range -1999 9999 (detection rate of 0.1 to 0.2 seconds / per channel) ◆ set independently for each channel signal type, range, alarm values ??◆ calibration function for each channel independently, effectively reducing sensor errors, improve the measurement and control accuracy ◆ can Close any unused channels, was closed after the channel not on display, alarm, print selection table contents code and description L / with 8 channels, 2:00 public alarm A- horizontal dimensions 160 × 84 × 182 B- vertical Formula 84 × 160 × 182 C- square 160 × 160 × 182 D1- desktop, 318 × 104 × 300 D2- panel mounted, 318 × 104 × 300 the number of channels □□ size of A, B meter up to 32 channels; size C, D meter up to 80 channels of the input signal (the other input signal, when ordering, Note 1) R all channels are heat resistance, the instrument includes a built-in indexing number: Pt100, Cu100, Cu50, BA1, BA2, G53 E All channels are thermocouple, the instrument includes a built-in indexing number: K, S, R, B, N, E, J, TB all channels are 4mA ~ 20mA or 1V ~ 5V and other current and voltage signals, to be in the order When clear current, voltage signal input channel X input of heat resistance, thermocouple mix L input is RTD, thermocouple, 4mA ~ 20mA, 0mA ~ 10mA, 1V ~ 5V, 0V ~ 5V mix. When ordering a clear need current, input channel communication interface voltage signal (Note 2) S0 no communication interface S1 RS-232 Interface S2 RS-485 interface to the print function (with hardware clock) (Note 2) P Print Interface P1 Integrated Print Interface (only D-type instrument) instrument power V0 85V AC ~ 265 V AC V1 12 V DC ~ 36V DC extended alarm TT: indicates an expansion alarm function, the standard 2:00 extended to 4:00, there is no non-standard functions can be omitted NN: indicates non-standard features, no real shot pictures may be omitted
