        Features:

        • Sixteen normally-open relay outputs organized into four independently commoned groups provide flexible switching for AC and DC field devices.
        • Strong electrical isolation of 250 VAC continuously and 1500 VAC for one minute is provided both from field circuits to the backplane and between output points.
        • Front-panel LED indication, wide field-voltage compatibility, and support for Series 90-30 and RX3i systems simplify installation, monitoring, and replacement in industrial control cabinets.
        General Electric IC693MDL940 provides a practical interface between PLC logic and field equipment that requires relay-based switching. Industrial systems frequently need to energize devices operating at voltage levels different from the internal PLC electronics, and relay outputs provide electrical separation between control logic and external loads. Sixteen output points allow several devices to be managed from one module. Four separate common groups also give panel designers greater flexibility when arranging field circuits. Applications can include machine control, process equipment, auxiliary devices, and status signaling.

        In everyday operation, IC693MDL940 converts PLC output commands into physical relay contact operation. Normally-open contacts close when corresponding output points are energized, allowing externally supplied AC or DC power to reach connected equipment. Individual LEDs give maintenance personnel immediate visual confirmation of output states without requiring software access for every basic status check. The hinged identification insert also provides a convenient location for wiring information and circuit labels. Such features are useful during commissioning, maintenance, and troubleshooting.

        General Electric IC693MDL940 also fits applications where existing Series 90-30 installations need continued support or where RX3i systems use compatible legacy I/O. Relay switching allows the same module type to work with different categories of field devices within the specified voltage and current limits. Proper enclosure installation, external field power, suitable circuit protection, and suppression for inductive loads help maintain reliable operation. The red high-voltage identification band provides a visible indication that higher field voltages may be present. Combined mechanical, electrical, and diagnostic features make the module useful for industrial output control where isolated relay contacts are preferred.

        The IC693MDL940 General Electric Relay Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        General Electric IC693MDL940 provides 16 normally-open relay output circuits arranged in four groups of four outputs. Each group has a common power output terminal, allowing field loads to be organized into separate switching groups according to application requirements. The rated voltage is 24 VDC or 120/240 VAC, while the operating range extends from 5 to 30 VDC and from 5 to 250 VAC at 50/60 Hz. Each output can switch loads up to 2 A for pilot-duty applications, with a maximum of 4 A per common and 16 A for the complete module.

        IC693MDL940 can control a broad range of externally powered devices, including motor starters, solenoids, and status indicators. Internal relay operation receives power from the +24 VDC bus on the PLC backplane, while AC or DC power for connected field devices must be supplied separately by the user. A minimum load of 10 mA is specified, and the relay circuits can tolerate a maximum inrush current of 5 A. Both ON and OFF response times are specified at 15 ms maximum.

        Electrical separation is an important operating characteristic of General Electric IC693MDL940. Isolation from field circuits to the backplane and frame ground is rated at 250 VAC continuously and 1500 VAC for one minute. Point-to-point isolation carries the same rating, helping separate individual relay switching circuits in industrial control installations. No fuses are built into IC693MDL940, so external protection requirements must be considered as part of the overall field circuit design.

        Operating status can be viewed directly from the front of IC693MDL940 through 16 green LED indicators. Eight LEDs in the upper row identify points 1 through 8 as A1 through A8, while eight LEDs in the lower row identify points 9 through 16 as B1 through B8. The hinged door contains an insert with wiring information on the inner surface and space for circuit identification on the outer surface. A red color band identifies IC693MDL940 as a high-voltage module.

        General Electric IC693MDL940 can be installed in any compatible I/O slot in a Series 90-30 or RX3i system, including I/O positions in 5-slot or 10-slot Series 90-30 baseplates. The module draws 7 mA from the 5 VDC backplane bus and 135 mA from the 24 VDC relay bus when all outputs are energized. For inductive loads, suppression circuits can help relay contact life approach the contact life obtained with resistive loads. The supplied technical guidance identifies a 1N4935 1 A, 200 V diode as an example for DC load suppression, while resistor-capacitor networks can be applied to AC loads.

        IC693MDL940 is considered open equipment and must therefore be installed inside an appropriate protective enclosure. The minimum enclosure level described for normal installation corresponds to NEMA/UL Type 1 or IP20 protection in an IEC 60529 pollution degree 2 environment. In hazardous-area applications, the system containing IC693MDL940 must be installed inside an ultimate enclosure that can only be accessed by using a tool. Such installation requirements support safer integration of exposed high-voltage relay circuits into industrial control cabinets.
