Pass & Seymour 1070B Magnetic Latching Relay, 24VAC/24VDC Control, Nylon Shell

The Pass & Seymour 1070B is a magnetic latching relay built for 24VAC/24VDC control circuits, operating on a momentary impulse rather than continuous power. Its split coil design energizes the ON coil to close the line contacts and the OFF coil to open them, giving installers reliable remote switching for lighting and low-voltage control applications. Housed in an insulated flame retardant nylon shell and UL and CSA Listed, the 1070B mounts through a standard 1/2" knockout via a noise suppressing nylon ring and can be installed in any position.

Key Features

  • Control Voltage: Operates on 24VAC/24VDC momentary impulse control for simple low-voltage switching.
  • Durable Construction: Insulated flame retardant nylon shell protects internal components and adds electrical insulation.
  • Mounting: Mounts in a standard 1/2" KO through a noise suppressing nylon ring; can be mounted in any position.
  • Split Coil Design: Energizes the ON coil to close line contacts and the OFF coil to open contacts, eliminating the need for continuous holding current.
  • Pre-Wired Leads: Prestripped 5-1/2" (140mm) #22 AWG leads simplify field wiring and reduce install time.
  • Low Power Draw: Draws just .520 mA, minimizing load on control circuits.
  • Ambient Temperature Rating: Rated for use up to a maximum ambient temperature of 140°F (60°C).

Pass & Seymour 1070-B – Frequently Asked Questions

1) Does the Pass & Seymour 1070B latching relay need constant power to hold its position?
No. The 1070B is a magnetic latching relay with a split coil: a momentary impulse to the ON coil closes the line contacts, a momentary impulse to the OFF coil opens them. Once switched it stays put with no holding current, so a momentary low-voltage switch or a relay panel pulse is all it needs. That is the main difference from a standard control relay that must stay energized to keep contacts closed.
2) How does the Pass & Seymour 1070B mount in a junction box or relay panel?
It mounts through a standard 1/2 inch knockout using a noise suppressing nylon ring, and it can be installed in any orientation, so you are not fighting position in a crowded panel or a tight outlet box. Body dimensions are 3.156 in high by 1.176 in wide.
3) Is the 1070B relay UL Listed for commercial lighting control work?
Yes, the 1070B carries both UL Listing and CSA Listing, which is what an institutional or MRO spec typically calls for on low-voltage lighting control relays. The housing is insulated flame retardant nylon.
4) Can the 1070B replace an existing split-coil latching relay in an older low-voltage lighting system?
That is one of its intended uses: split-coil latching relay retrofits, along with remote relay panels for commercial lighting and momentary switch controlled systems. Match the existing setup on two points before you pull the old one, the 24VAC/24VDC control and the separate ON and OFF coil leads. If the existing relay is a three-wire split coil driven from momentary switches, the 1070B drops into the same 1/2 inch knockout.
5) My control circuit is line voltage, not 24V - is the 1070B still the right relay?
No. The Pass & Seymour 1070B is built for a 24VAC/24VDC control circuit and operates on a momentary impulse to its split ON and OFF coils, so a line-voltage control signal is outside what it is rated for. For line-voltage switching in a lighting application, the Leviton ODS0D-IAW is a wallbox device that operates at 120/208/220/230/240/277VAC, 50/60Hz and switches through dual relays with a 30 second to 30 minute time delay. Keep the 1070B where a low-voltage momentary control scheme is already in place.
6) Can a Leviton ODS0D-IAW occupancy sensor be used instead of a Pass & Seymour 1070B latching relay?
They do different jobs in a lighting control scheme. The Pass & Seymour 1070B is a magnetic latching relay that switches the line contacts when it receives a momentary impulse on a 24VAC/24VDC control circuit - it needs a control signal from somewhere else, such as a momentary switch or relay panel. The Leviton ODS0D-IAW is a passive infrared wallbox occupancy sensor with dual relays, both photocell controlled, a low profile 180 degree field of view, a 30 second to 30 minute time delay, and line-voltage operation at 120/208/220/230/240/277VAC, 50/60Hz. The sensor originates the switching decision at the wallbox; the 1070B carries out remote switching from a low-voltage command. If the goal is automatic occupancy-based control in a single room, the sensor is the device; if the goal is remote or centralized switching driven by a 24V control circuit, the latching relay is.
7) Does the 1070B come with leads, or do I have to wire to terminals?
It ships pre-wired with prestripped leads, 5-1/2 inches (140mm) of #22 AWG. No terminal screws to land, so it wire-nuts straight into the control conductors and the switched line leg inside the box.
8) Can I install this relay in a hot ceiling plenum or an attic?
The 1070B is rated to a maximum ambient of 140 degrees F (60 degrees C). Above that it is out of spec. Within that range, position does not matter, since it can be mounted in any orientation.
9) What is the difference between a latching relay like the 1070B and a plug-in electromechanical relay?
The 1070B is a self-contained latching relay that mounts in a 1/2 inch knockout and holds state after a momentary 24V pulse. A plug-in electromechanical relay such as the Square D Harmony RXG13BDPV, 10A with 1 changeover contact, seats in a socket on a DIN rail inside a control panel and holds position only while its coil is energized. Pick the 1070B for distributed switching in boxes and low-voltage lighting control; pick the socketed plug-in when you want a replaceable relay in a panel with standard contact arrangements.
10) Is this relay an occupancy sensor, or do I need a separate sensor to switch it?
The 1070B is a switching relay only, with no sensing of its own. It needs something to send the momentary 24V pulse, a low-voltage momentary switch, a lighting control panel, or a time clock. If you want the sensing built into the wall device instead, a wallbox occupancy sensor like the Leviton ODS0D-IAW is the different product, and it is line voltage rather than 24V control.
11) Is the Pass & Seymour 1070B suitable for commercial-grade lighting control work?
Yes. The 1070B is UL Listed and CSA Listed, housed in an insulated flame retardant nylon shell, and rated to a maximum ambient of 140 degrees F (60 degrees C), which suits remote relay panels for commercial lighting and momentary switch-controlled relay systems. Among comparable lighting control devices, the Leviton ODS0D-IAW occupancy sensor is specified as commercial grade for wallbox occupancy sensing. The two are commonly specified on the same job - the sensor at the room, the latching relay at the panel.
12) What part number do I order for the Pass & Seymour black latching relay?
Order Pass & Seymour 1070B, manufacturer part number 1070-B. Black nylon body, 24VAC/24VDC control, made in Mexico. There is one configuration, so there is nothing further to specify on the order.
