This type of transformer provides isolation from your power distribution system and is often used as a “step down”...
Page 51: Special Considerations
A constant voltage transformer must have a sufficient power rating for its load. Excessive Noise When operating the SLC 500 controller in an environment with a high amount of electrical noise, give special consideration to the possibility of electrical interference.
Page 52 2-26 Selecting Your Hardware Components Potential sources of noise include inductive loads, such as relays, solenoids, and motor starters when operated by “hard contacts” like push buttons or selector switches. Suppression may be necessary when such loads are connected as output devices or when connected to the same supply line that powers the controller.
Page 53 Out 6 Out 7 DC COM or L2 If you connect an SLC 500 controller triac output to control an inductive load, use varistors to suppress noise. Choose a varistor that is appropriate for the application. Rockwell Automation recommends the following surge supressors for triac outputs when switching 120V ac inductive loads: •...

Page 55 Suitable surge suppression methods for inductive AC load devices include a varistor, an RC network, or an Allen-Bradley surge suppressor. These components must be appropriately rated to suppress the switching transient characteristic of the particular inductive device.

Page 57 The duration of the transient pulse is reduced when the on-state load current is increased. The duration of the transient pulse is proportional to the load impedance. This is illustrated in the following graph. 1000 On-State Load Current (mA) Allen-Bradley PLCs Publication 1747-UM011C-EN-P - December 2001...
Page 58 2-32 Selecting Your Hardware Components Increasing the load current by 100 mA decreases the EXAMPLE transient time from approximately 7 ms to less than 2.5 ms. To calculate the size of the resistor added in parallel to increase the current, use the following information: 24V = your applied voltage Need 100 mA of load current to reduce the transient...
Page 59 Chapter System Installation Recommendations To help you install the SLC 500 programmable controller as safely and securely as possible, follow the specific recommendations in this chapter. For general installation guidelines, also refer to the requirements specific to your region. • Europe: Reference the standards found in EN 60204 and your national regulations.
Page 60: Typical Installation
Air temperature in the enclosure must be kept within a range of 0°C to +60°C (32°F to +140°F). Be careful of metal chips when drilling mounting IMPORTANT holes for the controllers. Do not drill holes above a mounted SLC 500 controller. Publication 1747-UM011C-EN-P - December 2001...
Page 61: Preventing Excessive Heat
Preventing Excessive Heat For most applications, normal convection cooling will keep the SLC 500 controller components within the specified operating range of 0°C to +60°C (+32°F to +140°F). Proper spacing of components within the enclosure is usually sufficient for heat dissipation.
Page 62: Grounding Guidelines
Grounding Guidelines In solid-state control systems, grounding helps limit the effects of electrical noise due to electromagnetic interference (EMI). The ground path for the SLC 500 controller and its enclosure is provided by the equipment grounding conductor. Normal Electrical Noise Conditions Severe Electrical Noise Conditions 5.2 mm...
Page 63 System Installation Recommendations Ground connections should run from the chassis and power supply on each SLC 500 controller and expansion unit to the ground bus. Exact connections will differ between applications. Europe: Reference EN 60204 for safety information on grounding.

Page 66: Master Control Relay
System Installation Recommendations Master Control Relay A hard-wired master control relay (supplied by you) provides a convenient means for emergency controller shutdown. Since the master control relay allows the placement of several emergency-stop switches in different locations, its installation is important from a safety standpoint.

ATTENTION voltage surges when switching inductive loads such as motors, motor starters, solenoids, and relays. To avoid damage to your SLC 500 power supply in these applications, use an isolation transformer to isolate the power supply from harmful voltage surges.
Page 69: Loss Of Power Source
It is also possible that the voltage level may drop substantially below the normal line voltage range for a period of time. Both of these conditions are considered to be a loss of power for the system. Allen-Bradley PLCs Publication 1747-UM011C-EN-P - December 2001...

Page 175: Software Considerations
Setting Node Addresses The best network performance occurs when node addresses start at 0 and are assigned in sequential order. SLC 500 processors default to node address 1. The node address is stored in the processor status file (S:15L). Processors cannot be node 0. Also, initiators such as personal computers should be assigned the lowest numbered addresses to minimize the time required to initialize the network.
Page 176 SLC 500 fixed and SLC 5/01 processors can be selected by two initiators maximum at the same time. Using more than two initiators to select the same SLC 500 fixed and SLC 5/01 processors at the same time can cause communication timeouts.
