WiEPOut™ T1 Wireless Contact Closure & I/O Bridge
Mirrors switch states and DC signals between two locations. One encrypted 915 MHz link replaces up to 5 wired signal paths, with no Wi-Fi, Bluetooth or facility network.
Two identical units per link: what you wire into one side appears on the other.

Details
Documentation →How it works
- Linking is automatic at power-on.
- Momentary and maintained signals both carry across.
- Solid-state switching, no mechanical relays or moving parts.
- USB interface for monitoring and automation.
Channels & I/O
- 2 opto-isolated channels, 1-way
- Use as switch inputs or controlled outputs
- Stateful, follows switch position
- 3 bidirectional lines, 2-way
- 5–48 V user-supplied reference (VSS, pin 9); works down to 3.3 V, 5 V recommended
- Per-line direction control
Switches DC loads up to 48 V directly. For AC, drive a contactor or control relay, not line voltage.

FAQ
Is WiEPOut a wireless relay / contact-closure pair?
Yes. Wire a signal into one unit and it shows up on the other—same job as an industrial wireless relay or contact-closure kit. No Wi-Fi, Bluetooth, or plant network; just an encrypted 915 MHz link between two identical boxes.
Can it control a pump, gate, or motor remotely?
Yes. Put a switch, pushbutton, or PLC output on one side; the far side follows into that equipment’s control circuit. It drives DC loads up to 48 V. For AC, use it to pull in a contactor or control relay—not the line voltage itself.
Can I skip trenching cable between two buildings or across a yard?
That’s what it’s built for. Power each end with 12 V DC and let the radio carry the signals. One pair replaces up to five wired paths: two dry-contact channels plus three PinSync DC lines.
How far does the wireless link reach?
Up to 1,000 ft line of sight, tested outdoors with both units 6 in. above ground. Walls, metal buildings, terrain and vegetation between the units reduce range, so confirm the link at your site before relying on it.
Will it work as a wireless e-stop or machine interlock?
It can carry an interlock or e-stop signal when you can’t run conduit. It is not a certified functional-safety e-stop (no SIL/PLd rating). Use it only where your risk assessment allows a non-rated wireless path—not as a stand-in for a safety-rated chain.
Can a panel switch or pushbutton start something at a distance?
Yes. Wire the switch as a dry contact on one unit; the other closes into the starter, coil, or control input. Momentary or maintained—the far side simply follows the near side.
Does it need Wi-Fi, Bluetooth, or a network?
No. The two units talk directly over 915 MHz. No cloud, no SSID, no pairing. The free WiEPOut Host Service (REST, WebSocket, VISA/SCPI) is optional if you want automation or monitoring—basic mirroring doesn’t need it.
Why 915 MHz instead of 2.4 GHz?
Lower frequency usually means better range and wall penetration than crowded 2.4 GHz Wi-Fi and Bluetooth. Radio profiles let you favor faster response or a tougher link, depending on the site.
How many channels are there?
Two opto-isolated dry-contact channels and three PinSync DC lines (5–48 V reference; works down to 3.3 V, 5 V minimum recommended). That’s up to five mirrored paths per link, with solid-state switching.
Can a PLC or LabVIEW control it?
Yes. A PLC can drive the dry-contact inputs like any other contact-closure bridge. For test systems, the free WiEPOut Host Service adds REST, WebSocket, and VISA/SCPI (TCP 5025) for LabVIEW, NI-MAX, and similar tools—or talk UART at 115200 8N1.
What’s the difference between a link kit and a single unit?
A kit is simply two single units boxed together—everything you need for one link. A single unit is a spare, a replacement, or an add-on. Every unit, in a kit or on its own, comes with its own 12 V power adapter, mating terminal plug and USB cable. Every working link needs two powered ends.
