NT-RELAY Dual Remote Relay Module with Digital Input Triggers (IP-based)

The NT-RELAY is an Ethernet based, high performance communicating relay module that has two electro-mechanical relays, two optically isolated digital inputs, non-volatile memory and a real-time clock/calendar for full scheduling. The NT-RELAY includes its own built-in web server, allowing it to be used as a stand-alone device, using a standard browser. It can also be used with the NetX™ Command Center PC software, allowing simple point and click status, control and scheduling in the familiar software environment. The two digital inputs are associated with the two relays, allowing external alarms, photocells and switches to be used as inputs to trigger the relays in addition to the built in scheduling. A reference voltage is also supplied for the inputs, allowing for simple connections for most applications.

• Complete control, scheduling and status via any modern PC or Mac browser, including Internet Explorer, Firefox, Safari, Chrome
• Complete control, scheduling and status via NetX™ Command Center software version 4.6.0 or higher
• Password Protection for both setup and control
• Static IP address required, ensuring connection to the correct NT-RELAY module when multiple modules are installed in the same location or in the same NetX software project
• Status LEDs for each relay, each input, power and Ethernet connectivity and activity
• Integrated Modbus/IP control
• Up to 6 independent schedules per day
• Non-Volatile Memory for all schedules
• Battery backup included for the real time clock, with a minimum of 3 days of backup
• Module Dimensions: 3.88" H x 1.4" W x 3.0" D (without connectors)

NT-PWIRE Phantom Wire™ Creates a 24VAC Common Wire (for retrofit applications)

The NT-PWIRE Phantom Wire™ device allows the installer to connect any Net/X™ thermostat when a ‘common’ wire is not available in the existing thermostat cable. This handy device ‘creates’ a phantom wire. In many existing installations, older thermostat cables don’t have a common (24VAC common) wire because they were not needed for the mechanical thermostats originally installed. Years ago, it was typical for the cable to only have four (4) conductors. The NT-PWIRE creates the ‘common’ wire so the HVAC unit can be used along with any NetX thermostat or just about any other thermostat requiring a 24VAC common. Additionally, the NT-PWIRE includes screwless terminals, color-coded wiring for the HVAC unit connection, and LEDs on the unit to show power, heat, cool and fan calls are being created from the thermostat, practically eliminating troubleshooting.

• Creates a Phantom 24VAC Common Wire
• Use When There is One Too Few Conductors in Existing Thermostat Cable
• Integrated LEDs showing Power and Operation of Heat, Cool, and Fan
• Jumper Allowing Removal of LED functions if Not Desired
• Color-Coded Cabling for 5-wire HVAC connection at Equipment
• Screwless Terminals for Existing Thermostat Cable
• Wiring Diagram included on Case Cover for Easy Installation and Troubleshooting

NT-OSC & NT-OSW Occupancy Sensors

The NT-OSC and NT-OSW are occupancy sensors designed for automatic occupancy control of your HVAC system. They can be wall, corner or ceiling mounted to provide the best detection area for each application. The sensors provides an occupied / unoccupied signal to all Net/X™ Thermostats with CLK1/CLK2 terminals. A 4-wire cable (thermostat cable or CAT5) is all that’s needed for connection.

• Connects to any Net/X thermostat with the CLK1/CLK2 terminals
• No addressing needed; automatically recognized by the Net/X thermostat
• 24VAC Power supplied by the Net/X thermostat remote sensor bus
• Only one (1) CAT5 cable or 4-wire thermostat cable needed for installation
• Adjustable 'Verify Occupancy' times of 0 sec, 10 sec, 30 sec, 1 min, 5 min, and 10 min
• Adjustable 'Minimum Occupied' times of 10 sec, 1 min, 5 min, 10 min, 20 min and 30 min
