2 PM - Relays General Information The Joslyn Clark PM Family of control relays provides flexibility, versatility and reliability. The exclusive design concept and rugged construction of the PM line offers many advantages for the disigner and builder of today's complex control panels. Features: Modular Construction -allows field additon, replacement or conversion of poles for unlimited flexibility. Uniformity of Design -simplifies engineering, installation and maintenance. Interchangeability of Parts - reduces inventory requirements. Flexibility of Application - provided by many modifications including noble metal, gold bonded, anti-weld and overlapping contacts. Convertible Poles contain one contact, either NO or NC and can be easily field converted from one to the other. Identified be WHITE operating rod. Universal Poles contain two independent isolated contacts, one NO and one NC. Identified by RED operating rod. Duplex Poles contain two independent isolated contacts, both NO. Identified by GREEN operating rod. PMS Slim Jim Relays are - /" wide. They are the smallest members of the PM Family. Available with up to contacts; they provide the reliability of heavy duty 6 Volt relays in the smallest possible space. PM Convertible Pole Relays use white rod poles and are offered with up to 8 contacts in any combination of NO and NC contacts. Relays with up to contacts using double deck bases can be supplied.

3 General Information Relays - PM Type Relays, using universal poles have up to contacts. Relays with up to contacts are available, using some convertible poles. Type PMF Relays, combining several types of poles can have up to contacts. Type PMT Pheumatic Timing Relays, these relays are available for either "on-delay" operation (time delay after energization) or "offdelay" (time delay after de-engerization). They may also be field converted from on to "off-delay" and vice versa, by merely inverting the opertaing magnet. Type PMT Time Delay relays are adjustable over a timing range from. seconds to minutes with repetitive accuracy of + %. Latch Relays are available with either white rod convertible poles or red rod universal poles. The latching unit with continous duty trip coil replaces the two pole modules directly above the relay magnet.

12 PM - Relays DC Relays DC Relays - Type PM Bulletin 7 General Description Bulletin 7, Type PM, D-C Convertible Pole Relays feature many of the same time-proven advantages offered by the highly successful Bullentin 75 Type PM A-C Relay. For example, normally open poles are quickly and easily convertible to normally closed and vice versa. Each pole is contained in its own molded housing mounted by a single screw. Thus, each pole may be removed, installed or replaced individually without disturbing the others. The large double-break contacts are made of fine silver alloy, and are rated for both inductive and resistive loads.

For long trouble-free relay life, the D-C coil on Bullentin 7 Relays is molded with tough epoxy resin to keep out dirt and moisture, and to prevent physical damage. The magnet used is a vertical lift type with no springs that require adjustment. It is designed with pull-in characteristics that keep magnet slam to a minimum. Extra wide pressure terminals are front mounted for ready accessibility. As many as three lugs for No. wire can be connected to each terminal. Bullentin 7 Relays are available in,,,6 and 8-pole arrangements. Contact Ratings - Amps Continuous D-C Applications Ampere Interrupting Rating Resistive Load Non-Inductive Inductive Load Volts N.O.

13 DC Latch Relays Relays - PM DC Latch Relays - Type PML Bulletin 75 Bullentin 75, Type PML, D-C Latch Relays are identical in design, construction and dimension to the Type PML, A-C Convertible Pole Latch Relays except they incorporate the use of one "universal" pole on the relay to permit continouus application of voltage to the relay "Close" coil and latch "Trip" coil. The schematic diagram below illustrates how this is acccomplished. Up to 8 convertible poles in any combination of N.O. and N.C. contact arrangement are available for circuit use. The contracts can be readily converted in the field from N.O. to N.C. operation, and vice versa. The latch mechanism is the same rugged unit used on Type PML-A-C latch relays.

17 Coil Data Relays - PM Standard catalog listed AC relays ordered will have the proper coils as determined by the voltage and frequency suffix to the catalog number. Changing the circuit arrangement on a relay also changes the mechanical load on the magnet and may require a change of operating coil to assure proper operation. the information on this page will enable you to select the correct operating coil for any circuit arrangement required. Voltageampere requirements are provided to help in designing your panels. To select the proper operating coil for all For Example: Table indicates that the proper coil number for volts, 6 hertz application is TB-6, since the load factor of 68 falls within the Mechanical Load Range of 5 to 9. basic and latch relays except the Slim Jim, first determine the mechanical load on the magnet simply by totalling the load represented by the individual components operated by the magnet, using the mechanical load factors shown below. Select the proper coil from Table. When selecting the proper coil for Slim Jim Relays and Time Delay Relays, it is not necessary to determine the mechanical load Coil Application Tables - Type PM Relay Family Table factor.

See Rule "B" below. B. When installing DC contacts, using the contact sequence above, the last contact on the left must have two blowouts. All others will have only one. Example: If you have four contacts on the -pole base (table ), number must have two blowouts. If you have only two contacts, then number must have two blowouts. If you have six contacts on the 8-pole base (table ), number 5 must have two blowouts. Contacts seven and eight on the 8-pole base must have two blowouts. 5 5 Select and Price Base and Power Plant and Unit Poles Separately. Example: VAC Pole relay with N.O., N.C., Amp Poles.
