Event Gates IPIO

8 Digital Output 4 Digital Input IP based IO Device

Device Overview

The Event Gates IPIO is an industrial IoT controller designed for digital monitoring and control.

• Digital Outputs (DO): 8 Channels (Requires Interposing Relays)
• Digital Inputs (DI): 4 Channels (Dry Contact Only)
• Configuration: Logic states (NO/NC) are defined by software.

Digital Output (DO) Wiring

⚠️ IMPORTANT: Interposing Relay Requirement

To ensure the longevity of the device and protect internal components from high-voltage spikes or inductive kickback, we strongly advise against driving high-current loads directly.

You must use an interposing relay (external relay) between the Event Gates IPIO and the field device (e.g., motor, siren, lock).

Connection Steps:

1. Power Source: Use an external DC power supply appropriate for your external relay's coil voltage (typically 12V or 24VDC).
2. Circuit Loop:
   • Connect the Positive (+) of the power supply to the COM (Common) port of the IPIO Output bank.
   • Connect the DO Pin (1-8) of the IPIO to the Coil (+) of the external relay.
   • Connect the Coil (-) of the external relay back to the Negative (-) of the power supply.
3. Load Connection: Wire your actual load (light, motor, lock) to the contacts of the external relay, not the IPIO.

Digital Input (DI) Wiring

Mode: Dry Contact

The Digital Inputs on the IPIO are designed for Dry Contact sensors. This means the external sensor or switch should not inject voltage into the IPIO. It should strictly act as a passive switch.

Connection Steps:

1. Identify Pins: Locate the Input Pins (1-4) and the corresponding GND (Ground) or COM terminal on the input block.
2. Wiring: Connect one wire from your sensor (e.g., magnetic door sensor, push button, float switch) to the Input Pin. Connect the other wire to GND.
3. Operation: When the external switch closes (shorts to ground), the IPIO registers a "Triggered" or "Closed" state.

Note: Do not connect "Wet Contacts" (24VDC or 110VAC active signals) directly to the inputs, as this may damage the internal logic board. If you have a Wet Contact signal, use an isolation relay to convert it to a Dry Contact before connecting it to the IPIO.

Software

IPIO is running on its embedded firmware. Coded in Embedded C, this firmware is responsible of the whole IPIO functionality. IPIO Firmware supports following features.

Emergency Preset

IPIO is expected to be connected by a VIS service to fulfil its purpose. It defines the state in which it has no connection to any VIS service and it can be set to a predefined output state for all its 8 digital output to react to such an emergency case. Emergency preset can be set by the IPIO Manager.

Mute Input and Preset

VIS can be placed in stand-by mode via a designated input on the IPIO module. When this input is activated, the IPIO notifies VIS for logging purposes and forces all outputs into predefined preset states, ignoring any output commands from VIS during this period. Input values continue to be transmitted to VIS without modification.

VIS logs both mute and unmute events and can optionally send notification emails for these transitions. Detection and logging functions remain fully active during mute; only output control is affected. The video log clearly indicates the mute state during recorded events. By default, the mute input is assigned to input channel 1.

Precedence

Mute overrides emergency. If the IPIO is set to mute, it will remain its mute preset even if it loses all connection to VIS instances. If muted during emergency, IPIO will abandon emergency and resume mute preset.
