产品描述

DCM 4800型是一个交流或直流供电的集合变送器，最多可用于四个称重传感器，输出选项为0-20毫安、4-20毫安或0-10伏直流电压。所有输入/输出选项都包含在电路板上，因此无需使用DCM 4800指定输入/输出参数。DCM 4800有一个内置的励磁电源，能够在10伏直流电压下输出高达120毫安的电流。DCM 4800提供三路隔离、输入输出和电源，消除了不必要的接地回路问题。在正常的室温范围内，总的准确度<+0.1%。考虑到大皮重补偿要求，DCM 4800可以在10伏直流电激励下皮重达到3毫伏/伏称重传感器输出的80%。如果需要高/低设定点、警报/控制，则DCM 4800板被布置成接受Opto-22输出继电器。可使用电位计调整高低触发点。

The model DCM 4800 is an AC or DC powered summing transmitter for up to four load cells with output options of 0-20 mA, 4 to 20 mA or 0-10 Vdc. All input/output options are included on the board so there is no need to specify input/output parameters with the DCM 4800. The DCM 4800 has a built-in excitation supply capable of delivering up to 120 m A at 10 Vdc. The DCM 4800 offers three way isolation, input to output and power, eliminating unwanted ground loop problems. Overall accuracy over the normal room temperature range is excellent at <+0.1 %. Designed with large tare offset requirements in mind, the DCM 4800 can tare off up to 80% of the output of a 3 mv/v load cell at 10 Vdc excitation. If high/low setpoint, alarms/controls are desired, the DCM 4800 board is laid out to accept Opto-22 output relays. Potentiometers are accessible to adjust the high and low trip points.
