The IC694MDL645D (also IC694MDL645) is a 16‑point discrete DC input module from the PACSystems RX3i series. The IC694MDL645D accepts 24 VDC signals and can be wired for either positive or negative logic, making it compatible with a wide range of field devices including pushbuttons, limit switches and proximity sensors. Each input channel on the IC694MDL645D is optically isolated from the backplane, and sixteen green LEDs provide immediate on‑/off‑state indication. The IC694MDL645D also supplies +24 V OUT and 0 V OUT terminals to power two‑wire sensors directly, simplifying field wiring and reducing the need for external power supplies.
Industrial automation systems (packaging lines, conveying systems, material handling)
Machine tool cells interfacing with safety interlocks and operator stations
Process control plants (power generation, steel mills, cement works, water treatment)
Manufacturing cells with banks of 24 V DC proximity switches and photoelectric sensors
Distributed control systems (DCS) and PLC‑based safety interlocking
16 high‑density input channels: Sixteen points in a single group with a common power input terminal maximize I/O density and reduce panel space.
Positive or negative logic configuration via wiring: One SKU handles both sourcing (PNP) and sinking (NPN) sensors by choosing the appropriate reference (common connected to 0 V or +24 V).
Built‑in +24 V OUT and 0 V OUT terminals: Directly powers two‑wire proximity switches and sensors, eliminating external power supplies for many applications.
Optical isolation (field‑to‑backplane): Rated at 250 VAC continuous, 1500 VAC for one minute, protecting the controller from electrical noise and transients.
16 green LED status indicators: One LED per channel provides immediate visual confirmation of input state for rapid on‑site diagnostics.
Wide 0–30 VDC input range: Accepts signals across a broad voltage span while maintaining reliable on/off detection thresholds (11.5 V minimum on‑state).
Low backplane power consumption: Draws only 80 mA from the 5 V bus, reducing thermal load on the rack.
Flexible installation: Can be installed in any I/O slot of an RX3i Universal Backplane and supports insertion/removal with power applied (field terminal block must be removed first).
Class I Division 2 hazardous location certification: Suitable for installation in classified locations when used with appropriate enclosures and wiring methods.
Converts 24 VDC field signals from switches, sensors, and pushbuttons into discrete logic states for the RX3i CPU over the backplane.
Selects positive logic (sourcing/PNP) or negative logic (sinking/NPN) through wiring configuration, adapting to the sensor type without hardware changes.
Supplies +24 VDC field power to two‑wire proximity switches and pushbuttons via the module’s own +24 V OUT and 0 V OUT terminals, eliminating the need for an external power supply.
Optically isolates the field signals from the backplane to block electrical noise and ground loops.
Provides real‑time input status feedback to the CPU for use in control logic, interlocking, and annunciation functions.
Q1: What types of input logic does the IC694MDL645D support?
A1: The IC694MDL645D supports both positive and negative logic configurations, set by how the field devices are wired to the module’s common terminal.
Q2: How many input channels does the IC694MDL645D have?
A2: The IC694MDL645D provides 16 discrete input channels in one group with a single common power input terminal.
Q3: Can the IC694MDL645D power external field devices?
A3: Yes. The module includes +24 V OUT and 0 V OUT terminals that can supply power to two‑wire proximity switches, pushbuttons, and other low‑power sensors.
Q4: What is the isolation rating of the IC694MDL645D ?
A4: Field‑to‑backplane isolation is 250 VAC continuous, 1500 VAC for 1 minute. If the +24 V OUT terminals are used, the isolation reduces to 50 VAC continuous, 500 VAC for 1 minute.
Q5: What is the minimum on‑state voltage for an input to be recognised as ON?
A5: The on‑state voltage threshold is 11.5 VDC. Inputs from 11.5 V to 30 VDC are read as logic 1 (ON).
