IDTECK EIO88-X Expansion I/O Board for iTDC-X Access Controller, 8 Inputs, 8 Relay Outputs

Product information

IDTECK EIO88-X – Expansion I/O Board for iTDC-X Access Control Systems

IDTECK EIO88-X is an optional input/output expansion board designed for the IDTECK iTDC-X access control controller. It provides 8 additional inputs, 8 FORM-C relay outputs and 4 additional Wiegand reader ports, enabling an existing two-door access control system to be expanded to four doors.

The expansion board is suitable for commercial and professional security installations requiring additional door contacts, exit buttons, electric locks and alarm devices.

Expand Access Control from 2 to 4 Doors

The standard iTDC-X controller supports two doors. By installing the EIO88-X expansion board, the system can be extended to control doors 3 and 4.

Four additional inputs can be configured for exit buttons and door contact sensors, while four relay outputs can be assigned to door locks and alarm devices.

This allows installers to expand the access control system without replacing the main controller.

8 Additional Input Ports

The EIO88-X provides 8 additional inputs (Input 9–16) for connecting compatible input devices.

These inputs can be used for exit buttons, door contacts and other signals required by the access control system, depending on the configuration.

8 FORM-C Relay Outputs

The expansion board features 8 FORM-C relay outputs (Relay 9–16) with COM, NO and NC contacts.

These outputs provide flexible switching options for compatible electric door locks, alarm devices and other access control components.

4 Additional Wiegand Reader Ports

The EIO88-X includes 4 additional Wiegand reader ports (Reader 5–8).

These connections enable the integration of additional access control readers for the expanded door management configuration.

Direct Installation onto the iTDC-X Mainboard

The EIO88-X is installed above the iTDC-X mainboard using mounting supports and screws.

This board-mounted expansion design provides a compact way to increase the controller's input and output capacity within the existing system.

LED Status Indicators

The expansion board includes dedicated indicators for easier installation and troubleshooting:

• Power LED: A red indicator confirms that power is being supplied normally.

• MCU Status LED: A blinking indicator confirms normal microcontroller operation.

These indicators help installers verify the operating status of the expansion board.
