Multipole relay configurations include: I/O helper medium/large capacity, plug-in medium/large, stationary type, and plug-in type RB3P-GU. Multipole relays have 3-5 poles, a direct DC control range from 1V 1mA to 230 VAC, and up to 1,000,000 operations at 50 W. Input/output PCB relay configurations include: RI Series medium/large, RI series auxiliary, RIW Series IO, and RIU Series I/O. Input/output PCB relays have minimum operational power ratings ranging from 1V 1mA up to 24V imA. RIU Series I/O relays units feature 4, 8, 10, and 16 contacts per unit.

Macromatic Industrial Controls offers: voltage monitor, pump seal failure, intrinsically-safe, alternating, and 3 phase monitor relays. Plug-in voltage monitor relays come in two configurations: overvoltage/undervoltage and voltage band. Voltage monitor relays have nominal voltages ranging from 12 DC to 240 VAC, and a time delay on drop-out of 0.1-10 seconds. Pump seal failure relays feature single or dual channels, 8 & 11 pin octal sockets, and an optional fixed sensitivity setting. Intrinsically-safe relays feature an isolated 10A SPNO output contact, and a 24 or 120V AC input voltage. Alternating relays come in duplex and triplex configurations. Duplex has three output versions available: SPDT, DPDT, and DPDT cross-wired. 3 phase monitor relays range in nominal voltage from 120V to 480V, and the maximum overvoltage rating is fixed at 110% (of nominal). Other products offered by Macromatic Industrial include: current sensing relays, custom engineered products, time delay, etc.

March Electronics, Inc. offers Magnecraft relays in plug-in & power, solid state, time delay & sensor, power, latching & sequencing, and printed circuit board configurations. Plug-in & power relays come in low level and standard types, and have a contact rating range from 1 to 20 A. Solid state relays come in DIN, panel, PCB, and socket mount types. Output voltage ranges from 30-50 to 48-660. Time delay & sensor relays have a rated current load range from 3 to 15 and three contact configurations: 4PDT, DPDT, and SPDT. Power relays feature open style, flange cover, and DIN cover styles. Latching & sequencing relays have a maximum coil voltage rating of 120 VAC/VDC, and a variety of control types, including: dual coil, sequencing, and single coil. Printed circuit board relays offer an optional clamping diode, and a nominal input voltage range of 12 VDC to 240 VAC.

c3controls offers general purpose and electric timing relays. General purpose relays come in flange mounted, miniature square base with pin, square base, and octal base. Blade and pin terminals (5A-25A) are available from 1-pole to 4-poles. Relays also come in hermetically sealed octal and miniature square base configurations. These have applications for Division 2 Group A-D, and Class 1 hazardous locations. 2-4 pole devices are offered with 12A, 10A, and 5A ratings. Electric timing relays feature multi, single, and dual functions. Timing ranges from 0.0 seconds up to 9,999 hours for applications that require complex timing. These relays measure 17.5 to 45 mm wide, and are available with multi-voltage supply design.

Olympic Controls Corp. offers hermetically sealed, environmentally sealed, and dust tight relays. Hermetically sealed relays have applications for: altitude changes, salt spray, sand, dust, splashing water, and corrosive atmospheres. Standard switching configurations include: 51C, 34C, 48A, 36A, and 24C. Environmentally sealed relays have applications for: salt spray, sand, splashing water, and corrosive atmospheres. They feature 60 circuits switched in a 2 3/4" x 1 5/8" x 4 1/2" limited space, and are protected with an epoxy seal. Dust tight relays come in multi-contact and hybrid configurations. Operating temperature ranges from 0 to 55°C.
