Mechanical Latch Attachment – Mounts on any 2 through 8 pole relay (except XMO master relay). The Type XL and XDL latch attachments are identical in size and mounting provisions. The Type XL AC latch attachment has a continuous-duty-rated coil which is replaceable. The Type XDL DC latch attachment has an intermittent–rated coil (replaceable) and should be con-nected through a N.O. contact of the basic relay if the input signal is maintained to the unlatch coil. | |||||||||||

 |
Pneumatic Timer Attachment – Mounts on any 0 through 4 pole AC or DC relay (except XMO master relay). It provides 1 N.O. and 1 N.C. convertible timed contacts, which are the same Type XC-1 cartridges used on the basic relay. Two timing ranges are available, and conversion from On Delay to Off Delay or vice versa is easy. | |||||||||||
| Off Delay 0.2–60 seconds 5–180 seconds |

 |
Timer Lockout Cover – Fits over the time delay adjustment knob of any Type XT timing attachment. The Lockout Cover is designed to protect the time setting against accidental adjustment. It mounts directly to the timing attachment with two included screws. | — | ||||||||||
 |
Adder Decks – Adder decks are used to expand the number of poles on a relay. The basic 4 pole relay can be easily converted to an 8 pole or 12 pole relay by installing one or two adder decks. The Class 8501 Type XB20 comes with 2 convertible contact cartridges and will accept 2 additional convertible contact cartridges. The Class 8501 Type XB40 comes with 4 convertible contact cartridges. The same Type XB adder deck is used for both the middle and upper decks of the AC or DC relay. | |||||||||||

| Logic Reed Adder Deck – Used for switching low energy circuits. The Logic Reed Adder Deck is supplied with either one or two logic reed cartridges fixed into the center positions of an adder deck. Contact cartridges are neither convertible nor replaceable. Standard cartridges can be inserted in unused cavities of the Logic Reed Adder Deck. One or two Logic Reed Adder Decks may be added to the basic 4 pole relay. See Application Data on Page 5 for electrical ratings. | Number of N.O. Logic Reed Contact Cartridges | Number of N.C.

Contact Cartridges – The
Type X relay offers 4 Types of contact cartridges. All are color–coded
for visual identification of each Type.
NOTE: For additional
information regarding contact cartridge see Product Data.

||||||||||
| Standard Cartridge – The standard cartridge, used for most applications, has a black case. | ||||||||||||
| Overlapping Cartridge – Same NEMA Type A600 AC rating as standard cartridge and a NEMA Type P150 DC rating. When it is used in the N.O. mode it will close early and when used in the N.C. mode it will open late. If two or more are used together, the N.O. contacts will close before the N.C. contacts open as the relay picks up. Overlap also occurs during dropout. Overlapping cartridge has a red case. | ||||||||||||
| May
be ordered factory installed: Substitute 1 N.O. and 1 N.C. overlapping cartridges for 2 standard cartridges. Substitute 2 N.O. and 2 N.C. overlapping cartridges for 4 standard cartridges. |

| Master Cartridge – Features the same contact ratings as the Type XC1 standard cartridge except it has a 20 Ampere continuous current rating instead of 10 Amperes. It can be used in circuits where a master relay is required. Master cartridge has a blue case. Maximum of 6 master cartridges may be used on any 7 and 8 pole AC relays. Do not use any master cartridges on 9-12 pole AC or any DC-operated devices. | ||||||||||||
| Logic Reed Cartridge – See Logic Reed Adder Deck above. | — | |||||||||||
 |
Mounting Track – The mounting track has pre-punched mounting holes to simplify mounting the track on the control panel. The relay mounting screws are factory installed on the track so that the relays can be hung prior to tightening the screws. | |||||||||||
| 9'' long for 4 relays | — | |||||||||||
| 18'' long for 8 relays | ||||||||||||
| 27'' long for 12 relays | ||||||||||||
| 36'' long for 16 relays | ||||||||||||
| 72'' long for 32 relays | ||||||||||||
 |
Manual Test Tool – Provides a means of manually switching the contacts of a basic relay or timing relay and holding all contacts in their switched state until the tool is removed. This simplifies the checking of control circuits without power on the coil or contacts. |
|
||||||||||
| Transient Suppressor – Consists of an R-C circuit designed to suppress coil generated transients to approximately 200 percent of peak voltage. It is particularly useful when switching the Type X relay near solid state equipment. It is designed for use on coils up to 120 Vac. | ||||||||||||
 |
NEMA
Type 1 Enclosure – Formed from sheet steel to provide strength
and rigidity. Two conduit knockouts are located in both the top and
bottom of the enclosure. The enclosure is furnished with self tapping
screws for mounting the relay inside the enclosure. Accom-modates
a single 4 or 8-pole AC or DC relay, 12-pole AC relay, 4-pole AC latching
relay, and 4-pole AC timing relay.
NOTE: The 4-pole DC latching relay,
4-pole DC timing relay, 8-pole AC and DC latching relays and 12-pole
Utility Auxiliary Relay will not fit.
