GRX-IO is a 3K/4K contact-closure A/V control interface for GRAFIK Eye® 3000/4000 series control unit. It integrates a GRAFIK Eye® lighting control system with equipment that has a contact-closure I/O including motion and occupant sensors, Timeclocks and push buttons, Motorized projection screens, skylights, window shades, and movable walls, AV equipment and security systems. May be programmed to control any combination of one to eight GRAFIK Eye® 3000 or 4000 Series control units.

Provides five inputs and five outputs
Provides both normally open (NO) and normally closed (NC) contacts
Using the inputs, contact closures in other equipment can operate control units to:
- Select scenes
- Adjust scenes to reflect status of movable walls
- Turn lights on or off based on room occupancy
Using the outputs, scene changes in control units can:
- Trigger outputs to control other equipment
- Provide status feedback to other equipment

Operating Temperature (Maximum): 104 F
Operating Temperature (Minimum): 32 F
Certifications: UL
Current Draw: 0.10 Amps
DC Voltage: 24 Volts
Depth: 1.06 in
Height: 4.26 in
Width: 5.26 in
Power:
- IEC PELV/NEC® Class 2
- Operating voltage: 12 V 200 mA
- Provides 2-way interface between preset lighting controls and dry contact closure devices.
- Provides 5 inputs and 5 outputs. Outputs can control other manufacturers’ equipment.
Operating Modes:
- Scene selection
- Special functions
- Partitioning
- Occupant sensor
STATUS LEDs:
- Five Status LEDs light when associated output is active (on).
System Communications and Capacity:
- IEC PELV/NEC® Class 2 wiring connects GRX-IO Interface to control units and other components. Counts toward system maximum of 16 wallstations/control interfaces (3 powered from one GRAFIK Eye® control unit without external 12 V power supply; GRX-IO counts as two devices toward the maximum of three connected to one GRAFIK Eye® 3000 control unit).
Relative humidity: <90 % Non-condensing
Five Input Terminals:
- Accept maintained inputs and momentary inputs with 40 msec minimum pulse times.
- Off-state leakage current must be less than 100 µA.
- Open circuit voltage: 24 V maximum.
- Inputs must be dry contact closure, solid state, open collector, or active-low (NPN)/active high (PNP) output.
  - Open collector NPN or active-low on-state voltage must be less than 2 V and sink 3.0 mA.
  - Open collector PNP or active-high on-state voltage must be greater than 12 V and source 3.0 mA.
Five Output Terminals:
- Provide maintained or momentary (1-second) outputs.
- The GRX-IO is not rated to control unclamped, inductive loads. Inductive loads include, but are not limited to, relays, solenoids, and motors. To control these types of equipment, a flyback diode must be used (DC voltages only)
