产品概述 双回路数字/光柱显示控制仪 采用先进的微处理器进行智能控制,适用于温度、湿度、压力、液位、瞬时流量、速度等多种物理量检测信号的显示及控制，并能对各种非线性输入信号进行高精度的线性校正。 可同时对两路信号分别进行显示及控制，两路输入信号亦可为不同类型的信号。输入端口均具备万能信号输入，只需通过仪表菜单的简单选定，即可实现不同类型输入信号（各种热电偶、热电阻、标准电压/标准电流信号）之间的轻松切换，提高了仪表的通用性和可靠性。 采用高亮度LED数码显示和高分辨率光柱显示（比例显示），使测量/控制值的显示更为清晰直观。显示方式有两种：双屏数码显示、双屏数码+双光柱显示；控制方式：两路相互独立的继电器控制/报警输出或模拟量变送输出。输出回路均采用光电隔离，抗干扰能力强。可带串行通讯接口。 主要技术参数 输入信号 模拟量 •热电偶：标准热电偶—B、S、K、E、J、T、WRe3～25等 •电 阻：标准热电阻—Pt100、Cu50、Pt100.1、远传压力电阻:30～350Ω等 •电 流：0～10mA、4～20mA等（输入阻抗≤250Ω） •电 压：0～5V、1～5V、mV等（输入阻抗≥1MΩ） 输出信号 模拟量输出 •DC 4～20mA （负载电阻≤750Ω） DC 0～10mA （负载电阻≤1.5KΩ） •DC 1～5V （负载电阻≥250KΩ） DC 0～5V （负载电阻≥250KΩ） 开关量输出 •继电器控制输出: —ON/OFF(带回差) •触点容量（阻性负载）—AC220V/3A； DC24V/3A •可控硅过零触发脉冲输出(SCR)—可触发600V/100A可控硅 •固态继电器控制信号输出（SSR）—输出DC9V/30mA •可控硅过零触发输出—双向可控硅600V/5A 通讯输出 •标准串行通讯接口 通讯方式 •RS-232C，RS-485 波特率 •300bps～9600bps（自由设定） 馈电输出 •DC 24V，负载≤30mA
