1756-IB16 is a 16 channel isolated digital input module in the Rockwell Automation ControlLogix series. The input type of this module is digital input, supporting 24V DC voltage, with 16 input channels and a response time of only 1ms. It is installed on a DIN rail, with a nominal input voltage of 24V DC and a working voltage range of 10 to 31.2V DC. The total base power is 0.56 watts, with a power consumption of about 5.1 watts at 60 degrees Celsius and a heat dissipation of 17.39BTU/hour. The on state current range is from 2.0mA at 10V DC to 31.2V DC 10 milliampere hours, programmable filter time (0, 1 or 2 milliseconds), maximum hardware delay time of 2 milliseconds plus user configurable filter time, module isolation voltage of continuous 250 volts, with high reliability, fast response and flexible configuration capabilities, widely used in the field of industrial automation, suitable for collecting access control system door opening and closing signals, elevator operation status signals, lighting system switch signals, etc., to achieve intelligent management of various equipment and facilities in buildings.
Technical specifcations for 1756-IB16
Brand and Model: ControlLogix series digital input module produced by Rockwell Automation, model 1756-IB16.
Input type: digital input, for current absorption type.
Number of input channels: 16, divided into two groups, each with 8 points.
Input voltage:
Nominal input voltage: 24V DC.
Working voltage range: 10 to 31.2V DC, compatible with 24V DC industrial standard power supply, voltage fluctuation tolerance ± 15%.
Response time: 1ms.
power waste:
Total base plate power: 0.56W.
At 24V DC, the current consumption is only 2mA, and the full load power consumption is less than 5W (in a 60 ℃ environment), significantly reducing the heat dissipation pressure of the cabinet.
The current consumption at 5.1V DC is 100mA.
Isolation voltage: Continuous 250V, can effectively block interference between channels and between channels and ground, avoiding misoperation caused by signal coupling.
Hardware latency: The maximum hardware latency time is 2 milliseconds plus user configurable filter time (0, 1, 2, 9, or 18 milliseconds).
Filtering time: With Studio 5000 Logix Designer software, the 0/1/2ms input filtering time can be configured to meet the acquisition requirements of high-speed pulse signals (such as encoder feedback) or low-speed switch signals (such as limit switches).
Signal type compatibility: Supports multiple signal sources such as NPN/PNP proximity switches, relay contacts, photoelectric sensors, etc. Users do not need to configure additional signal conversion modules.
Channel level diagnosis: Real time monitoring of input short circuit and open circuit faults, and feedback of fault location through LED indicator lights and controller alarm logs.
Hot swappable support: The module supports live plugging and unplugging, and with the 1756-TBCH detachable terminal block, maintenance time is reduced to less than 5 minutes.
Installation method: DIN rail installation, directly installed to the 1756 local or remote chassis.
Working temperature: -20 ℃ to 70 ℃ (storage temperature -40 ℃ to 85 ℃).
Protection level: IP20 (module body).
Certification standards: UL, C-UL, CE, Class 1 Div 2, CCC, IECEx Scheme, ATEX, etc.
Physical dimensions: approximately 149mm (width) x 107mm (height) x 80mm (depth).
Weight: Approximately 0.5kg.
Communication interface: ControlLogix backplane bus (supporting EtherNet/IP and ControlNet protocols).
