2-channel digital input; 24 VDC; 3 ms; Diagnostics
This digital input module receives control signals from the field side and supplies a short-circuit proof voltage to the sensors. The module transfers the control signals and other information via a fieldbus coupler to the higher-level controller. Each input module has a noise-rejection filter. Each sensor can be supplied separately. A short circuit to ground is indicated as an error/fieldbus failure and a message is sent to the supervisory control. The error is canceled automatically after it has been rectified. Field and system levels are electrically isolated.
Number of digital inputs: 2
Total number of channels (module): 2
Signal type: Digital, Voltage
Signal type: 24 VDC
Supply voltage (sensor): 24 VDC; Each channel is supplied separately with a short-circuit-protected voltage. A short circuit to ground is indicated as an error/fieldbus failure and a message is sent to the supervisory control. The error is canceled automatically after it has been rectified.
Sensor connection: 2 x (2-wire, 3-wire)
Input characteristic: high-side switching
Input filter (digital): 3ms, 3ms
Input current per channel for signal (1) typ.: 3.7mA
Output current per channel: 0.5A
Short-circuit current: 1.5 A, pulsating due to thermal overload protection
Voltage range for signal (0): −3 … +5 VDC
Voltage range for signal (1): 15 … 30 VDC
Diagnostics: Short circuit, automatic acknowledgment after error rectified
Input data width (internal) max: 4Bit
Supply voltage (system): 5 VDC; via data contacts
Current consumption (5 V system supply): 12mA
Supply voltage (field): 24 VDC (-25 … +30 %); via power jumper contacts (power supply via blade contact; transmission via spring contact)
Isolation: 500 V system/field
Indicators: LED (A, C) green: Status DI 1, DI 2; LED (B, D) red: Error DI 1, DI 2
Number of incoming power jumper contacts: 2
Number of outgoing power jumper contacts: 2
Current carrying capacity (power jumper contacts): 10A
Connection technology: inputs/outputs: 8 x CAGE CLAMP®
Connection type 1: Inputs/Outputs
