LU-R/C 1300 series features

Combines recording and control in a single unit, with fully switchable universal input: supports thermocouple, RTD, standard voltage, standard current and other signals; output control modes include PID control, on/off control, auto-tuning control and manual control. It can accept 1 to 2 PID control channels or 1 to 4 signal inputs; each control board has independent signal input, main output and alarm output, with full isolation between inputs and outputs.

Programmable PID control with program curves of up to 100 segments; transmitter supply output is available.

Data storage: 64M built-in storage space, with each channel's recording interval independently adjustable from 1 to 3600 seconds; a high-capacity FLASH memory chip stores historical data with retention after power failure, and the internal storage time is 191 days to 1882 years; USB interface support allows data to be transferred to a USB flash drive to extend recording time.

Communication: the RS232 interface can connect to a portable computer or PDA to upload real-time/historical data, and the data can be analyzed, archived and printed via host computer software or USB flash drive utility software; the RS485 interface can connect to professional SCADA systems such as KingView and MCGS.

Display: supports overview, extra-large, bar graph, real-time curve, historical curve, alarm, system configuration, channel configuration and print setting screens; curve screens feature zooming, fully automatic playback of historical trends, time and amplitude zoom, and positioned queries of data for a specific year/month/day/hour/minute/second; channel tag names can be customized.

Hardware design: modular design for flexible configuration; different acquisition boards can be used simultaneously; complete electrical isolation between inputs and outputs reduces power supply radiation interference and improves reliability.

Operator interface: user-friendly HMI with operating hints on every screen, allowing operation without professional training; Chinese/English bilingual display interface.

Input impedance: current 250Ω; voltage 650KΩ; RTD requires three-wire resistance balance, lead resistance < 10Ω.

Input channels: 1-4 channels, each channel can accept a different signal type.

Thermocouple cold junction compensation error: ±1°C.

Output signal parameters

Output modes:

Current output: 0-10mADC (RL<1000Ω, extendable to 2000Ω); 0-20mADC (RL<500Ω, extendable to 1000Ω); 0-22mADC custom current (freely set by software).

Other outputs: solid-state relay drive (12V/50mADC); relay contact output; SCR zero-crossing trigger output (single-phase, three-phase); 24V power distribution (current < 200mADC).
