240 Volt AC Isolated Input, 8 Point - IC693MDL231

This module provides 8 isolated input points for 240 volt AC inputs for the Alspa C80–35 Programmable Logic Controller (PLC). Each input point has a common power input terminal. The input circuits are reactive (resistor/capacitor) circuits. When current flows into an input point, it registers as a logic 1 in the input status table (%I). The input characteristics are compatible with a wide range of user-supplied input devices, such as pushbuttons, limit switches, and electronic proximity switches. Power for the field devices must be supplied by the user. This module requires an AC power source and cannot be used with a DC power source.

LED indicators at the top of the module show the ON/OFF status of each input. The LED block features eight green LEDs, labeled A1 to A8 (representing points 1 to 8). There is an insert between the inside and outside surfaces of the hinged door. When the door is closed, the inside surface contains circuit wiring information, while the outside surface can be used to record circuit identification details. The left edge of the insert is color-coded red to indicate this is a high-voltage module.

This module can be installed in any I/O slot of a 5- or 10-slot baseplate in an Alspa C80–35 PLC system.

Key Features:

    Rated Voltage: 240 volts AC, 50/60 Hz
    Input Voltage Range: 0 to 264 volts AC, 50/60 Hz
    Number of Inputs per Module: 8 (each input has a separate common terminal)
    Isolation: 1500 volts RMS between the field side and logic side, 500 volts RMS between inputs
    Input Current: 15 mA (typical) at rated voltage

Input Characteristics:

    On-state Voltage: 148 to 264 volts AC
    Off-state Voltage: 0 to 40 volts AC
    On-state Current: Minimum 6 mA
    Off-state Current: Maximum 2.2 mA
    On Response Time: Maximum 30 ms
    Off Response Time: Maximum 45 ms
    Power Consumption: 60 mA from the 5-volt bus on the backplane when all inputs are ON

Since each input is isolated from the others, you can power each input with a separate AC power source. For more detailed information, please refer to the product data sheet.
