1756-LSC8XIB8I/A 是 Allen-Bradley(羅克韋爾自動化)生產的 ControlLogix 系列的低速計數器模塊。這個模塊具有 8 個輸入點和 8 個計數器,支持 24V 高速 DC 隔離輸入。它具備標準輸入或計數器控制功能,每個計數器都是獨立隔離的,最大計數頻率可達 40 kHz。模塊的計數范圍是 0 到 2,147,483,648(31 位計數器)。
該模塊需要與 1756-TBS6H 或 1756-TBCH 可拆卸接線盒(RTB)配合使用,以連接到兼容的 ControlLogix 機箱。1756-LSC8XIB8I 模塊的工作電壓范圍是 10 至 30 伏 DC,標稱輸入電壓為 24 伏 DC。在 5.1V DC 時的電流消耗為 275 mA,在 24V DC 時的電流消耗為 3 mA。背板總功率為 1.47W,關斷狀態(tài)下最大電壓為 5V,最大電流為 1.5 mA。導通狀態(tài)下電流范圍從 10V DC 時的最小 2 mA 到 30V DC 時的 5 mA。此外,模塊還具有 250V 的連續(xù)隔離電壓,并通過了 1500V 交流電 60 秒輸入到輸入和 2300V 交流電 60 秒輸入到背板的類型測試。熱耗散為 12.97 BTU/hr,螺釘至背板輸入的延遲時間(從關到開,反之亦然)為 14 μs 標稱值/23 μs 最大值+用戶可配置的 0 至 30,000 μs 濾波時間。工作溫度范圍為 0 至 60 攝氏度,非工作溫度范圍為 -40 至 85 攝氏度。在 10 至 500 Hz 時的振動為 2 g,工作沖擊為 30g,非工作沖擊為 50g
The 1756-LSC8XIB8I/A is a low-speed counter module in the ControlLogix series manufactured by Allen-Bradley (Rockwell Automation). This module has 8 input points and 8 counters and supports 24V high-speed DC isolated inputs. It has standard input or counter control, each counter is independent and isolated, and the maximum count frequency is up to 40 kHz. The counting range of the module is 0 to 2,147,483,648 (31-bit counter).
The module needs to be used with a 1756-TBS6H or 1756-TBCH detachable junction box (RTB) to connect to a compatible ControlLogix chassis. The 1756-LSC8XIB8I module operates in a voltage range of 10 to 30 volts DC, with a nominal input voltage of 24 volts DC. The current consumption is 275 mA at 5.1V DC and 3 mA at 24V DC. The total power of the backplane is 1.47W, the maximum voltage is 5V and the maximum current is 1.5mA when the backplane is turned off. The current in the on-state ranges from a minimum of 2 mA at 10V DC to 5 mA at 30V DC. In addition, the module has a continuous isolation voltage of 250V and has passed type tests of 1500V AC 60 seconds input to input and 2300V AC 60 seconds input to backplane. The heat dissipation is 12.97 BTU/hr, and the delay time from screw to backplane input (from off to on and vice versa) is 14 μs nominal value /23 μs maximum + user-configurable filtering time of 0 to 30,000 μs. The operating temperature range is 0 to 60 degrees Celsius and the non-operating temperature range is -40 to 85 degrees Celsius. The vibration at 10 to 500 Hz is 2 g, the working shock is 30g, and the non-working shock is 50g
