【产品详情】

产品所属品牌：美国Rockwell Allen-Bradley(AB)

  1756-OF6CI，6通道相互隔离的4~20mA电流模拟量输出模块。分辨率：13位。需配可拆卸端子块：1756-TBNH或1756-TBSH。

Allen-Bradley 1756-OF6CI模块是ControlLogix系列通用隔离模拟电流/电压输出模块。本模块有6个可用的独立隔离电流输出。它还在21毫安(2.7安)范围内具有13位分辨率。它需要1756年-TBNH或者1756年-TBSH可拆卸的端子板外壳(RTB ),然后才能安装到接地和已安装的机箱中。

可用的通信格式类型随着1756-OF6CI模块是整数和浮点格式。特征该模拟输出模块包括数据回声、斜坡/速率限制、箝位/限制、箝位/限制报警和初始化保持。这程序1756年的特色。

它有一个0至20毫安的范围低信号和用户计数为0毫安和-32768个计数，高信号和用户计数为21.074毫安和32767个计数。该模块在5.1V时的电流消耗为250毫安，从0至550欧姆端接于OUTs和RTN，从551至1000欧姆端接于OUTs和ALTs。在24V时，其电流消耗为225毫安(0至550欧姆，端接于OUTs和RTN ), 300毫安(551至1000欧姆，端接于OUTs和ALTs)。0至550欧姆的总背板功率为6.7瓦，551至1000欧姆的总背板功率为8.5瓦。对于0至550欧姆的负载，该模块的最大功耗为5.5瓦，对于551至1000欧姆的负载，该模块的最大功耗为6.1瓦。它没有开路检测，但有24V DC过压保护和限于21毫安或更低的短路保护。常规试验在1350伏交流电下持续2秒，其持续隔离电压为250伏。

【英文介绍】

Product brand: Rockwell Allen-Bradley(AB)

1756-OF6CI, 6 channels isolated from each other 4~20mA current analog output module. Resolution: 13 bits. Detachable terminal block 1756-TBNH or 1756-TBSH is required.

The Allen-Bradley 1756-OF6CI module is a ControlLogix series universal isolated analog current/voltage output module. This module has 6 independent isolated current outputs available. It also has a 13-bit resolution in the 21 mA (2.7 amp) range. It requires a 1756-TBNH or 1756-TBSH detachable terminal board housing (RTB) before it can be installed into a grounded and mounted case.

The types of communication formats available with the 1756-OF6CI module are integer and floating-point formats. The analog output module includes data echo, ramp/rate limit, clamp/limit, clamp/limit alarm, and initialization hold. This program features from 1756.

It has a range of 0 to 20 mah for low signal and user counts of 0 mah and -32,768 counts, and 21.074 mah and 32,767 counts for high signal and user counts. The module has a current consumption of 250 mA at 5.1V and is terminated from 0 to 550 ohms for OUTs and RTN and from 551 to 1000 ohms for OUTs and ALTs. At 24V, its current consumption is 225 mA (0 to 550 ohms, terminated at OUTs and RTN) and 300 Ma (551 to 1000 ohms, terminated at OUTs and ALTs). The total backplane power from 0 to 550 ohms is 6.7 watts and the total backplane power from 551 to 1000 ohms is 8.5 watts. For loads from 0 to 550 ohms, the module has a maximum power consumption of 5.5 watts, and for loads from 551 to 1000 ohms, the module has a maximum power consumption of 6.1 watts. It has no open circuit detection, but has 24V DC overvoltage protection and short circuit protection limited to 21 mA or less. The conventional test lasted for 2 seconds at 1350 volts AC, with a continuous isolation voltage of 250 volts.
