This item includes the basic carrier PCB along with an Omron G5LE-14-DC12 12 V relay, 5.0 mm terminal blocks, and 0.1" male headers in straight and right-angle versions. Surface-mount components are pre-assembled on the PCB, but the through-hole components are not installed. The included power relay is rated for up to 10 A under most conditions. ## Pricing - **Price:** $13.20 (inc GST) — $12.00 AUD, exc GST - **Quantity discounts:** 10+ $11.52 (exc GST) · 25+ $11.16 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 18 and Aug 21. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-2483:1` (comma-separated SKU:qty pairs) and share the link.

The modules are available with 5 V and 12 V power relays—Omron G5LE-14-DC5 and G5LE-14-DC12 (1MB pdf), respectively—and they are available pre-soldered or as partial kits that allow greater application flexibility: The [carrier board](https://core-electronics.com.au/pololu-basic-2-channel-spdt-relay-carrier-for-sugar-cube-relays.html) is available without the relay or connectors for those preferring to use their own relays that have the common “sugar cube” pinout and footprint, and Pololu also offers several [dual-relay carrier modules](https://core-electronics.com.au/pololu-basic-2-channel-spdt-relay-carrier-with-5vdc-relays-assembled.html). The carrier board routes the three relay control pins to 0.1"-spaced pins compatible with standard [solderless breadboards](https://core-electronics.com.au/prototyping/breadboards.html) and [female servo cable connectors](https://core-electronics.com.au/category/112/servo-cables). The assembled version of this board has a [0.1" straight male header](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html) soldered to these pins while the partial kit version includes 8×1 straight and [right angle](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-right-angle.html) 0.1" male header strips that can optionally be broken into 3×1 pieces and soldered in. The relay switch pins are routed to a set of large pads intended for use with a [3-pin 5mm-pitch terminal block](https://core-electronics.com.au/screw-terminal-block-3-pin-5-mm-pitch-side-entry-4-pack.html) and a set of smaller pads with a 0.2" pitch, making them compatible with 0.1" perfboards. The assembled version of this board has a terminal block soldered to these pins while the partial kit version includes a 3-pin terminal block that can be optionally soldered in. The carrier board has four mounting holes that work with #2 or M2 screws. **Advantages over similar products** - Compact layout - Two LEDs to indicate coil actuation - Zener diode for fast current decay on relay coil - Specification of electrical routing clearance rules on relay switch nodes **Comparison to the dual-channel version** Pololu's basic relay carrier boards are available in single-channel and dual-channel versions. The single-relay carrier is less than half the size of the 2-channel carrier (due in part to its smaller mounting holes and lack of barrel jack footprints), so it might be more appropriate to use two single-channel boards instead of one 2-channel board in some space-constrained applications. The following table shows some of the key differences between the two versions: | | Voltage options | Board size | Mounting hole size | \# of channels | DC power jack option | |---|---|---|---|---|---| | Single-relay carrier | [5 V](https://core-electronics.com.au/pololu-basic-spdt-relay-carrier-with-5vdc-relay-assembled.html) and [12 V](https://core-electronics.com.au/pololu-basic-spdt-relay-carrier-with-12vdc-relay-assembled.html) | 1.15" × 1" | 0.086" (#2 or M2) | 1 | no | | Dual-relay carrier | [5 V](https://core-electronics.com.au/pololu-basic-2-channel-spdt-relay-carrier-with-5vdc-relays-assembled.html) and [12 V](https://core-electronics.com.au/pololu-basic-2-channel-spdt-relay-carrier-with-12vdc-relays-assembled.html) | 1.5" × 1.8" | 0.125" (#4 or M3) | 2 | yes | **Using the relay module** The switch portion of the relay is accessible on one side of the board while the control pins are routed to the other. The relay coil is powered by supplying the appropriate coil voltage for your specific relay across the VDD and GND pins, and it is activated by a digital high control signal on the EN pin. The control signal is fed directly to a BSS138 N-channel MOSFET, which in turn actuates the relay coil when the control voltage exceeds approximately 2.5 V, up to a maximum of 20 V (see BSS138 datasheet (92k pdf) for details). The relay switch terminals COM (common), NO (normally open), and NC (normally closed) are routed on the PCB with a minimum clearance of 60 mils (1.5 mm) from other copper. The copper traces are designed to be at least 45 mil (1.1 mm) from the board edges, though manufacturing variations in the board edges can make those distances slightly lower. In most applications, the current and voltage ratings for the module will match the ratings of the relay used. Maximum current, maximum voltage, and life expectancy are interdependent; Pololu therefore recommends careful examination of your relay’s datasheet. **Warning:** This product is not designed to or certified for any particular high-voltage safety standard. Working with voltages above 30 V can be extremely dangerous and should only be attempted by qualified individuals with appropriate equipment and protective gear. **Schematic diagram** This schematic is also available as a downloadable pdf (131k pdf). **People often buy this product together with:** | [![0.100" (2.54 mm) Breakaway Male Header: 1×40-Pin, Straight, Black](https://core-electronics.com.au/attachments/localcontent/0J6370_2747ad6d8f.jpg)](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html) | [0.100" (2.54 mm) Breakaway Male Header: 1×40-Pin, Straight, Black](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html) | |---|---| | [![Female Crimp Pins for 0.1" Housings 100-Pack](https://core-electronics.com.au/attachments/localcontent/0J2472_35509fe5b9.jpg)](https://core-electronics.com.au/female-crimp-pins-for-0-1-housings-100-pack.html) | [Female Crimp Pins for 0.1" Housings 100-Pack](https://core-electronics.com.au/female-crimp-pins-for-0-1-housings-100-pack.html) | |---|---| | [![Male Crimp Pins for 0.1" Housings 100-Pack](https://core-electronics.com.au/attachments/localcontent/0J2474_27712ac106.jpg)](https://core-electronics.com.au/male-crimp-pins-for-0-1-housings-100-pack.html) | [Male Crimp Pins for 0.1" Housings 100-Pack](https://core-electronics.com.au/male-crimp-pins-for-0-1-housings-100-pack.html) | |---|---| **Dimensions** | Size: | 1" × 1.15" × 0.1"[1](https://core-electronics.com.au/#note1) | |---|---| | Weight: | 16 g | **General specifications** | Voltage: | 12 V | |---|---| | Partial kit?: | Y | **Identifying markings** | PCB dev codes: | 0J7111 | |---|---| | Other PCB markings: | 0J7111, 0J7194 | **Notes:** 1 Size of PCB.
