Features
- Response Time: On-state response time is typically 1 ms. Off-state response time is also typically 1 ms, ensuring fast and reliable input processing for real-time control and automation tasks.
- Power Supply Options:
- User-supplied power: Users can connect their own power supply for operating the field devices.
- Isolated 24V DC supply: The module can draw power from the isolated +24V OUT and 0V OUT terminals on the PLC power supply, providing power to a limited number of inputs.
- Isolation: The module provides 1500 volts of isolation between the field side and the logic side, offering protection for the PLC from potential voltage surges or electrical faults in the field devices.
- Input Characteristics:
- On-state voltage: The module recognizes inputs within the voltage range of 11.5 to 30 volts DC.
- Off-state voltage: The module recognizes off-state inputs within the range of 0 to +5 volts DC.
- On-state current: A minimum of 3.2 mA is required for the module to register an "on" input.
- Off-state current: A maximum of 1.1 mA is acceptable for the module to register an "off" input.
- Power Consumption:
- 5V power consumption: The module draws 80 mA from the 5V bus on the backplane when all inputs are activated.
- 24V power consumption: The module consumes 125 mA from the isolated 24V backplane bus or from a user-supplied power source.
Input Characteristics and Device Compatibility
- The module is engineered to accommodate a wide range of user-supplied input devices.
- These devices include limit switches, push buttons, and proximity switches. The dual logic capabilities positive and negative enhance its adaptability in different control systems, allowing for greater flexibility in designing and configuring PLC systems.
- Power for the operation of these field devices is typically provided by the user, either through a direct power supply or via an isolated +24VDC supply from the power supply unit.
LED Indicators for Status Monitoring
- At the top of the module, there are LED indicators that serve as visual aids to display the ON/OFF status of each input point. The LED block is divided into two horizontal rows, with each row containing eight green LEDs.
- The top row is labeled A1 to A8, corresponding to input points 1 through 8, while the bottom row is labeled B1 to B8, corresponding to input points 9 through 16. These LEDs are essential for quick status monitoring and troubleshooting in the field.
Wiring Diagram and Circuit Identification
- The module is designed with user convenience in mind, featuring an insert that fits between the inside and outside surfaces of the hinged door. The wiring diagram is located on the inside of this insert, providing a clear reference for installation and maintenance.
- On the outside surface of the insert, the circuit identification information is clearly displayed, facilitating easy access when needed. The outside left edge of the insert is color-coded blue, indicating that the module is classified as a low-voltage device.
- This color-coding aids in the quick identification of the module type during setup and maintenance.
Installation and Compatibility
- The module can be installed in any I/O slot within a Series 90-30 PLC system, offering flexibility in system design and expansion. It is designed to seamlessly integrate with the existing PLC infrastructure, providing reliable performance across various applications.
Electrical Specifications
- It operates within an input voltage range of 0 to 30 VDC. It has an input current rating of 7 mA, making it efficient in power consumption. The on-state voltage for the module ranges from 11.5 to 30 volts DC, ensuring reliable signal detection when inputs are active.
- The off-state voltage is specified as 0 to +5 volts DC. The on-state current is rated at a minimum of 3.2 mA, while the off-state current is limited to a maximum of 1.1 mA. These electrical characteristics ensure that the module performs optimally within its designed operating parameters, providing accurate and reliable input signal processing.
