Compact I/O High-speed Counter Module 7 Module Installation The 1769-HSC module is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments (Pollution Degree 2(1)) and with circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).(3) Removal and Insertion Under Power (RIUP) WARNING: When you insert or remove the module while backplane power is on, an electrical arc can occur.
Compact I/O High-speed Counter Module System Planning There are several factors to consider when planning your system: • A 1769-ECR (right-end cap) or 1769-ECL (left-end cap) is required to terminate the end of the Compact I/O bus. • Each bank of Compact I/O modules must have its own power supply. (A MicroLogix 1500 base unit acts as the power supply for modules directly connected to it.
Compact I/O High-speed Counter Module 9 Refer to the illustration when assembling the Compact I/O system. See page 6 for a description of the module. A D E C B G B F 45197 1. Disconnect the power. 2. Check that the bus lever of the module (A) is in the unlocked (fully right) position. 3. Use the upper and lower tongue-and-groove slots (B) to secure the modules together. 4. Move the module back along the tongue-and-groove slots until the bus connectors (C) line up with each other. 5.
Compact I/O High-speed Counter Module System Mounting ATTENTION: This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel. Additional grounding connections from the power supply's mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded. Refer to Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional information.

Important: Hole spacing tolerance: ±0.04 mm (0.016 in.).
Compact I/O High-speed Counter Module DIN Rail Mounting The module can be mounted on the following DIN rails: • EN 50 022 - 35 x 7.5 mm (1.38 x 0.3 in.) • EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.) ATTENTION: During panel or DIN-rail mounting of all devices, be sure that all debris (metal chips, wire strands, and so forth) is kept from falling into the module. Debris that falls into the module could cause damage on powerup. 1. Before mounting the controller on a DIN rail, close the DIN rail latches. 2.
Compact I/O High-speed Counter Module 13 If you feel excessive resistance, make sure that you disconnected the module from the bus and that you removed both mounting screws (or opened the DIN latches). TIP It may be necessary to rock the module slightly from front to back to remove it, or, in a panel-mounted system, to loosen the screws of adjacent modules. 6. Before installing the replacement module, be sure that the bus lever on the right-side adjacent module is in the unlocked (fully right) position.
Compact I/O High-speed Counter Module Grounding Guidelines • This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel. Additional grounding connections from the module’s mounting tabs or DIN rail (if used) are required only when the mounting surface is non-conductive and cannot be grounded. • Keep shield connection to ground as short as possible. • Ground the shield drain wire at the 1769-HSC module’s input end only.

Compact I/O High-speed Counter Module 17 Output Wiring Basic wiring(1) of output devices(2) to the module is shown in Figure 7. ATTENTION: Follow these guidelines: • Miswiring of the module to an AC power source or applying reverse polarity will damage the module. • Be careful when stripping wires. Wire fragments that fall into a module could cause damage at powerup. Once wiring is complete, be sure that the module is free of all metal fragments.
Compact I/O High-speed Counter Module Wire the Finger-safe Terminal Block When wiring the terminal block, keep the finger-safe cover in place. Wiring the Finger-safe Terminal Block Upper Retaining Screw Lower Retaining Screw 1. Loosen the terminal screws to be wired. 2. Route the wire under the terminal pressure plate. You can use the bare wire or a spade lug. The terminals accept a 6.35 mm (0.25 in.) spade lug. TIP The terminal screws are non-captive. Therefore, it’s possible to use a ring lug (6.
Compact I/O High-speed Counter Module 19 Wire the Modules After the module is properly installed, wire the modules by using this procedure. To provide proper operation and high immunity to electrical noise, always use shielded wire. ATTENTION: To prevent shock hazard, care should be taken when wiring the module to signal sources. Before wiring any module, disconnect power from the system power supply and from any other source to the module. Do not wire more than two conductors on any single terminal.
Compact I/O High-speed Counter Module Output Operation The four output terminals must be powered by a user-supplied external source. User-power range is from 5…30V DC. See Output Specifications on page 27 for voltage and current levels. There is no isolation between the outputs, but the outputs are isolated from the inputs and the 1769 Compact bus.
Compact I/O High-speed Counter Module 21 Transistor Output Transient Pulses The maximum duration of the transient pulse occurs when minimum load is connected to the output. However, for most applications, the energy of the transient pulse is not sufficient to energize the load. ATTENTION: A transient pulse occurs in transistor outputs when the external DC supply voltage is applied to the output common terminals (for example, via the master control relay).
Compact I/O High-speed Counter Module IN At module powerup, a series of internal diagnostic tests are performed. These diagnostic tests must be successfully completed or the module OK status indicator remains off or red, and a module error is reported to the controller.
