Physical Characteristics and Installation
This digital input module weighs approximately 0.23 kg for easy rack mounting. Its dimensions measure 120 mm x 80 mm x 35 mm for Procontic chassis slots. First, slide the 07 EB 90-S into a free I/O rack position. Then, secure the module using the built-in locking latches. Finally, connect your field devices to the removable screw terminals. LED indicators on the front show the status of each active channel.
Channel Configuration and Signal Characteristics
The 07 EB 90-S provides 16 digital input channels for versatile field connectivity. Each channel accepts 24V DC nominal signals from industrial sensors. The module draws only 8 mA per channel for reliable detection. Input impedance measures 3 kΩ for proper signal loading. Optocouplers isolate every input from the internal backplane bus. Consequently, this design protects the controller from electrical noise.
Response Time and Power Requirements
This input module delivers a fast 2 ms response time for time-critical applications. Each channel responds within milliseconds to any signal change. The 07 EB 90-S draws its operating power from the 5V DC backplane supply. The total current consumption reaches 150 mA under full load. You do not need any external power source for the logic circuits. The removable terminal block simplifies wiring replacement and maintenance tasks.
