1769-ECR 右端盖模块

Allen-Bradley 1769-ECR是一个右端盖(ECR)模块，与CompactLogix控制器系列一起使用。该模块作为总线终止器，终止FlexBus电路，发出CompactLogix组件结束的信号。该模块是限定CompactLogix配置所必需的。1769-ECR的特点是5.1 VDC下的5 mA电流。它的工作高度为2000米或6562英尺，重量约为130克或0.286磅。它具有开放式外壳等级，工作温度为0 -60°C或32-140°F)，而存储温度为-40至85°C(-40至185°F)，相对湿度为5-95%，不凝结。必须安装在震动不超过5g, 10- 500hz的位置。当安装DIN导轨时，它的工作冲击额定值为20g，当CompactLogix系统直接安装到外壳时，它的工作冲击额定值为30g。1769-ECR必须在系统断电时安装或拆卸。在未通电的情况下拆卸或插入将导致控制器错误和停机，这是不可取的，特别是对于功能和活跃的操作系统。要安装1769-ECR，必须将母线杠杆从接合位置抬起。完成后，将ECR模块与导向槽对齐，轻轻推动ECR模块，直到它与CompactLogix模块相邻并对齐。使用总线杠杆连接ECR模块并关闭FlexBus。如果在母线杠杆接触过程中感觉到阻力，检查ER是否正确对准模块和导槽。

艾伦-布拉德利1769- ecr是一个右端盖或终止终端的1769控制器的通信总线的结束。它在5V DC下的最大母线电流为5ma。它的操作高度为6562英尺，运输重量约为0.286磅。它有一个开放式的外壳，以确保安全，它可以适应一定的条件，以减少火灾和伤害的风险。为了满足健康和安全要求，1769-ECR在2区环境中应用时应安装IP54防护，因为它不耐受阳光和其他紫外线辐射源。1769-ECR的工作温度为32 – 140华氏度，可在寒冷、干热和热冲击环境中进行测试。它的非工作温度为40 – 185华氏度。在寒冷，干热和热冲击期间未包装测试。此外，1769- ecr5 – 95%的非冷凝相对湿度，其振动达到5 g在10 – 500赫兹测试运行期间。它有一个操作冲击是20克的DIN导轨安装和30克的面板安装。它的非操作冲击在DIN导轨上为30克，在面板安装上为40克。

The Allen-Bradley 1769-ECR is a Right End Cap (ECR) module that is used with the CompactLogix controller series. This module functions as a bus terminator, terminating the FlexBus circuitry, signaling the end of the CompactLogix assembly. This module is necessary to qualify the CompactLogix configuration. The 1769-ECR features a current draw of 5 mA at 5.1 VDC. It has an operating altitude of 2000 m or 6562 ft and approximately weighs 130 grams or 0.286 lb. It has an open style enclosure rating, an operating temperature of 0 -60 °C or 32-140 °F) while the storage temperature is -40 to 85 °C (-40 to 185 °F and relative humidity of 5-95%, non-condensing. It must be installed at a location with vibration not exceeding 5 g, 10-500 Hz. It also has an operating shock rating of 20g when DIN rail is mounted and 30g when the CompactLogix system is directly mounted to the enclosure. The 1769-ECR must only be installed or removed when power is removed from the system. Removal or insertion under power will cause controller error and stoppage which is not desirable especially with a functional and actively operating system. To install the 1769-ECR, the bus lever must be lifted from its engaged position. Once done, align the ECR module along with the guide slots and gently push the ECR module until it is adjacent and in line with the CompactLogix module. Engaged the bus lever to connect the ECR module and close the FlexBus. If resistance is felt during the engagement of the bus lever, inspect if the ER is properly aligned to the module and the guide slot.

The Allen-Bradley 1769-ECR is a right end cap or terminator that terminates the end of the communication bus of a 1769 controller. It has a maximum bus current draw of 5 mA at 5V DC. It comes with an operating altitude of 6562 feet and an approximate shipping weight of 0.286 lbs. It has an open-type enclosure to ensure safety and it can adapt to certain conditions to reduce the risk of fire and injury. To meet health and safety requirements, the 1769-ECR should be installed with IP54 protection when applied in zone 2 environments because it has no tolerance for sunlight and other UV radiation sources. The 1769-ECR has an operating temperature of 32 – 140 deg. F tested in cold, dry heat, and thermal shock environments. It has a non-operating temperature of 40 – 185 deg. F tested unpackaged during cold, dry heat, and thermal shock. The also 1769-ECRhas a 5 – 95% noncondensing relative humidity and its vibration reaches 5 g at 10 – 500 Hz tested during operating. It has an operating shock is 20 g on a DIN rail mount and 30 g on a panel mount. Its non-operating shock is 30 g on a DIN rail and 40 g on a Panel mount.
