ProXR Relay Expansion Board with 32-Channel High-Power Relays
This Relay Expansion Controller includes 32 on-board high-power relays, capable of switching 20 or 30-Amps of current, depending on the variant chosen. This relay expansion controller is designed to plug into our ProXR series industrial relay controllers, and includes the required XR Relay Expansion Controller cable. On-Board status LEDs indicate the on/off status of each relay. This expansion controller operates on 12 Volts DC, and may be powered by connecting two-wires to the on-board screw terminal connector, or by plugging in power supply (sold separately) with a 2.1mm center positive barrel connector. Please allow up to 3 Amps of Power Consumption at 12VDC when all relays are ON (including surge currents).

Relay Options
20-Amp SPDT High Power Relay Option
This controller is available with a 20-Amp relay option, allowing control of high-power loads up to an absolute maximum of 240VAC at 20 Amps. Ideal for high-power switching applications, this relay should never be used for low-power signals. The 20-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. This relay is Rated at 20-Amps between NO and C. Do not exceed 10-Amps between C and NC connections. This relay uses .250″ Quick Connect terminals (optional accessory) to connect to the top side of the relay. The relay is molded with COM, NC, and NO markings into the plastic. Review Datasheet

Hiph-Power Relay Controller Specifications
This table covers all NCD High-Power Relay Controllers. All ratings assume 12VDC operation at 70°F (21°C). Please note that most ratings are estimated and may be subject to periodic revision. Some ratings represent stock controller settings without performance enhancement optimizations. The estimated processing time can be impacted by background services and choice of commands. Standby power consumption assume no communications module is installed and no relays are active on the controller. Please add the power consumption of the activated relays and communications module to obtain a better estimation of power consumption.| Specifications of NCD SPDT Relay Controllers | Minimum | Nominal | Maximum | Notes |
