Solenoid Valve Output Module IC693MDL760 Product Description GFK-1881A November 2000 Description The module is accessed from the logic program as a standard 16-point output module. When using VersaPro version 2.0 (or later version) programming software, it should be configured by its catalog number. When using programming software other than VersaPro version 2.0 (or later version), the module must be configured as a standard 16-point generic output module. The module is enclosed in a standard IC693 plastic housing. 4 5 6 7 8 9 10 11 1 2 3 4 5 Solenoid Valves 3 DC Outputs The five 24VDC outputs can each drive up to a maximum 0.5A, with a limit of 2.0A total for all five points. Field wiring is connected to these outputs via a 10-pin connector located on the front panel. The user must provide 24VDC to this connector to power the positive logic outputs, which source current to the field connections. This group of five discrete outputs is electrically isolated from the PLC backplane; however, the outputs are not individually isolated from each other. 2 1 2 3 4 5 6 7 8 9 10 Pendent A 12-pin connector, located on the module’s front panel, allows the user to connect the optional IC693ACC760 Solenoid Forcing Pendent, described later. PWR 1 DC Outputs This IC693MDL760 output module provides eleven pneumatic outputs and five 24VDC sourcing outputs. For each pneumatic output, the module contains an internal 3way solenoid-actuated valve and an associated output fitting, which is located on the front panel. When an output is turned ON, its internal valve connects a usersupplied pressure source (100 psi maximum) to the output fitting. The pressure source is connected to the fitting on the bottom of the module. When the output is turned OFF, the valve’s output port is vented to atmosphere inside the module. Solenoid power is supplied from an external 24VDC source to the “DC Outputs” connector on the front panel. Figure 1.

Optional IC693ACC760 Solenoid Forcing Pendent The IC693ACC760 Solenoid Forcing Pendent is an optional system maintenance tool. This pendent is a small hand-held unit containing eleven switches, one for each valve. Each switch is labeled to allow the user to easily establish a correlation between any given switch and its corresponding valve. The pendent is attached to the Solenoid Valve Output Module via the 12-pin connector, labeled “Pendent,” on the module’s front panel. With solenoid power applied (to the DC Outputs connector), the user may turn the solenoids ON and OFF with the pendent switches. This pendent is intended to allow maintenance personnel to operate the valves during shut down periods when the main power to PLC system has been turned off. If the pendent is attached during normal operation (with the PLC system running), a command from the PLC can turn a valve ON even if the pendent switch for that valve is in the OFF position, and a pendant switch can turn a valve ON even if the PLC is commanding it to be OFF. LED Operation This module has 17 LED indicators (see Figure 1): • Solenoid Power - 1 LED, labeled PWR, indicates presence of solenoid power. • Point Status - 16 LEDs, labeled 1-11 and 1-5, indicate individual I/O point ON/OFF status. The solenoid valve status LEDs (the top group, labeled 1 to 11) are powered from the 24VDC external Solenoid Power source; these LEDs will not illuminate unless this power source is present. The “PWR” LED indicates the presence of external solenoid power. Each valve status LED illuminates while its corresponding valve is open (valve coil is energized), whether by PLC command or by use of the Solenoid Forcing Pendent. The discrete output LEDs (the bottom group, labeled 1 to 5) are powered from the PLC backplane and can illuminate even if the external DC Output field power (24VDC) is off. 4 Solenoid Valve Output Module GFK-1881A Field Wiring Two AMP brand .025 square double-row .100 X .100 shrouded male pin headers provide the field connection to the five 24VDC discrete outputs and the Solenoid Forcing Pendent. These connectors have detent windows to retain the mating field connector. The field connectors are not supplied with the module; however, the optional pendent comes with cable and connector. See the next section, “Field Connectors,” for specifications. Table 4.

Use the following guidelines to install the fittings on the module: • Place the provided gasket over the threaded end of the fitting and carefully push it over the threads until it stops against the hexagonal shoulder. • Carefully thread the fitting into the manifold by hand. • Tighten the fitting to a maximum of 7 to 9 inch/pounds. Caution Overtightening may cause a fitting to crack or snap off, or could result in thread damage. Limit tightening torque to 7 to 9 inch/pounds. 6 Solenoid Valve Output Module GFK-1881A Pneumatics Installation and Safety Requirements Since the IC693MDL760 module’s internal valves exhaust inside the module, it is important that you adhere to the following guidelines: • Compressed air or other inert gas used in the module’s valves must be clean and dry. No water, oil, or other contaminants can be tolerated in the air/gas stream. The presence of these will cause module failure and possible damage to surrounding components. • Only clean, dry, compressed air or inert gas may be used. Use of an explosive or flammable gas will result in explosion or fire if used with this module. • The module should not be used in an airtight, unvented cabinet. Use in an airtight cabinet could result in the cabinet becoming pressurized, which could lead to personal injury and equipment failure. Warning Failure to follow the above “Pneumatics Installation and Safety Requirements” can result in personal injury, module failure, and damage to associated equipment. Compatibility Hardware This module is a standard size IC693 module, compatible with all IC693 series CPUs and baseplates. It will function in any CPU, Expansion, or Remote baseplate. Software When configuring this module with VersaPro version 2.0 (or later version), it should be configured by its catalog number. When configuring with programming software other than VersaPro version 2.0 (or later version), the module must be configured as a standard 16-point generic output module. Scan Time Contribution This module has the same scan time contribution rating as a standard 16-point output module, as specified in the I/O Scan Time Contribution tables in Chapter 2 of the IC693 PLC CPU Instruction Set Reference Manual.
