The IC693MDL655 is Series 90-30 discrete input component. This module offers 32 channels designed for 24VDC signaling, which are compatible with both positive and negative logic wiring setups. It accommodates an input voltage window from 0 to 30 VDC along with a 7 mA input current. When active, it draws 195 mA at 5VDC and 224 mA at 24VDC from the backplane electrical rail.
Flexible Dual-Logic Terminal Routing and Power Supply Modes
The 24 volt DC Positive/Negative Logic Input module for the Series 90-30 Programmable Logic Controller provides 32 discrete input points. The inputs are arranged in four isolated groups of eight (A1 - A8, B1 - B8, C1 - C8, and D1 - D8); each group has its own common. The inputs are positive or negative logic inputs and will operate at levels up to 30V.
Backplane isolation between the field side and logic side is provided by opto-couplers on the module. Isolation is also provided between the four groups of inputs on the module, however each group of eight inputs is referenced to the same user common connection. There are no special fault or alarm diagnostics reported. LED indicators (labeled A1 - A8, B1 - B8, C1 - C8, D1 - D8) at the top of the module provide the ON/OFF status of each input point.
This module is configured as a 32-point input type and uses 32 bits of discrete %I input data. Current into an input point results in a logic 1 in the input status table. Power to operate field devices can be supplied by the user, or from the isolated +24 VDC supply available at the module’s I/O connectors. This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC system. Connections to the input circuits are made from the user’s input devices to two male (pin-type) 24-pin connectors (Fujitsu FCN-365P024-AU) mounted on the front of the module. The connector mounted on the right of the module (front view) interfaces with groups A and B. The connector on the left side of the module interfaces with groups C and D.

Oil & Gas
In oil refineries or natural gas gathering stations, it is used to collect 24VDC status signals from various remote limit and level switches inside explosion-proof control enclosures, utilizing a 1500V isolation barrier to protect the core PLC microprocessor.
Water Treatment
In municipal water plants and wastewater treatment aeration basin control systems, it monitors the bulk status of open/close limit auxiliary contacts on large motorized water pump valves.
Thermal Power
Deployed in power plant balance of plant (BOP) systems, its sub-2 ms rapid response capability ensures precise and synchronized signal acquisition from trip safety switches in boiler feedwater pump interlock loops.
Steel & Metallurgy
In steel plant blast furnace material distribution, heavy-load converters, and steel rolling production lines, it centrally captures proximity sensor pulses from heavy machinery positioning mechanisms via twin 24-pin connector interfaces.
Automotive
On distributed I/O racks of car body welding and assembly lines, it supports both positive and negative logic (sink/source) configurations to centrally collect switch states from massive field pneumatic clamps and safety door interlock pushbuttons.
Lithium Battery
Inside the PLC control panels of lithium battery electrode coating, calendering, and precision winding machines, its built-in optocouplers strongly absorb high-frequency noise interference from inverter switching, ensuring zero-distortion sensor data acquisition.
When operating the IC693MDL655, notice that its 32 channels utilize high-density physical interfaces, which require external interconnection via two groups of dedicated Fujitsu 24-pin male connectors, and it is highly recommended to directly adapt genuine IC693CBL327 or IC693CBL328 pre-wired shielded cables.
At the chassis level, the module supports interconnection with any I/O slot across Series 90-30 main, expansion, or remote baseplates. Regarding electrical distribution, although it allows flexible wiring for both positive and negative logic (sink/source) configurations, technicians must ensure that the input level remains within the safe thresholds of 18 to 30 VDC for startup and 12 to 30 VDC for runtime (with a nominal 24 VDC), maintaining an on/off signal response limit within 2 ms.
While a 1500 V AC optocoupler isolation barrier is internally integrated, standardized wiring practices should still be enforced to prevent electromagnetic noise interference, and during routine maintenance, the electrical path state can be verified through the grouped LED status matrix clearly labeled with identifiers A, B, C, and D.
The IC693MDL655 is a High-density, digital input module that is part of Emerson Automation’s Series 90-30 Programmable Logic Controller (PLC) platform. This input module is designed to be installed to any Series 90-30 baseplate whether CPU baseplate, I/O Expansion baseplate or Remote I/O baseplate. It is directly mounted to any available I/O slot of a 5-slot or 10-slot baseplate and occupies single sot only. Additionally, this module is compatible for use with embedded 90-30 CPUs and modular 90-30 CPUs. Being a high-density input module, it features Thirty-Two (32) input points, grouped in Four (4) with Eight (8) inputs per group. Each channel is compatible to be wired with On/Off type of devices that operate at voltage signal range of 0-30 VDC and nominal voltage of 24 VDC. Typical On/Off devices used with this module are limit switches, level switches, proximity switches, auxiliary contacts, pushbutton devices and other devices that are operating similarly. Unlike other digital input modules, the IC693MDL655 uses Two (2) male 24-pin type connectors with ordering number Fujitsu FCN-365P024-AU. This is pre-mounted on the front panel of the module that interfaces to input groups A, B, C and D. This requires use of pre-wired cables which are separately purchased. Compatible pre-wired cables are IC693CBL327 and IC693CBL328. Additionally, this cable can be custom built. The IC693MDL655 is also provided with LED status indicators that with group identifiers as well. LED indicators are labelled as A1-A8 (Group 1); B1-B8 (Group 2); C1-C8 (Group 3) and D1 - D8 (Group 4).
