- Availability: Out of Stock
- Warranty: 2 years
- Categories: Smart Alarm System > Accessories > Expander Module
The Trikdis IO4R is an expansion module designed specifically for GATOR gate controllers, adding 4 inputs and 4 relay outputs to extend system functionality. It is an ideal choice for flexible control and state monitoring in gate automation systems.
Key Features
- 4 inputs and 4 relay outputs in a single module
- EOL (8.2 kΩ) input monitoring for reliable operation
- Relay outputs with NC/NO contacts
- RS485 communication for GATOR systems
- Remote control and system intervention capability
- Fast diagnostics with LED indicators
Inputs
The inputs support 8.2 kΩ EOL (End-of-Line) configuration, providing stable and reliable state monitoring. They are suitable for safety sensors, limit switches, or external control signals. The input voltage range spans from 0 V up to supply voltage, ensuring compatibility with various gate system components.
Relay Outputs
The 4 relay outputs feature NC/NO contacts, making them suitable for switching a variety of devices. They can be used for gate triggering, system reset, or implementing bypass logic. Switching capacity is up to 125 V / 1 A (30 V DC).
An optional 8.2 kΩ output resistor configuration is also available for monitored output scenarios.
GATOR System Integration
The IO4R connects to GATOR gate controllers via RS485 communication, ensuring stable and real-time data exchange. The module operates as a native extension of the GATOR system, providing immediate response to input events and remote commands.
Ideal for installations requiring additional control points, automation logic, or remote intervention capability.
Remote Control and Bypass Function
The module enables remote execution of critical actions, including temporary bypass of safety sensors. This is particularly useful in fault situations where system operation must be restored quickly without an on-site visit.
Status Indication and Diagnostics
Built-in LEDs support fast troubleshooting:
- POWER LED – supply voltage status (normal / low)
- TROUBLE LED – RS485 communication fault
- Input and output state indication
Installation
The compact design allows easy integration into gate automation enclosures. Connection is made via power supply, RS485 bus, and input and relay output terminals.
Suitable for both new installations and upgrades to existing systems.
