Honeywell|PUB6438SR-CHN|BACnet-Programmable Spyder Controller
Description
The HONEYWELL PUB6438SR-CHN is a BACnet-programmable Spyder controller with an onboard relay designed for efficient control of HVAC and building systems in industrial and commercial applications.
Features
- Supports BACnet MS/TP communication for seamless integration.
- Includes onboard relay for direct equipment control.
- Offers flexible programming for customized automation.
Technical Specifications
- Power Supply: Operates on 24 VAC ±20% or 20-30 VDC, ensuring versatile power compatibility.
- Power Consumption: Maximum 10 VA at 24 VAC, optimizing energy use.
- Processor: Features a 32-bit processor running at 48 MHz, providing robust processing capability.
- Memory: Equipped with 512 KB SRAM and 512 KB Flash, supporting complex control logic.
- Communication: Utilizes BACnet MS/TP at baud rates from 9.6 kbps to 115.2 kbps, enabling reliable data exchange.
- Inputs: Includes 6 universal inputs (UI), configurable for 0-10 VDC, 4-20 mA, or resistive signals, with 10-bit A/D resolution.
- Outputs: Provides 4 analog outputs (AO) at 0-10 VDC with 8-bit D/A resolution and 3 relay outputs rated at 24 VAC, 2 A max.
- Relay Contact Rating: Handles 24 VAC at 2 A per relay, suitable for direct equipment switching.
- Operating Temperature: Functions from 32°F to 122°F (0°C to 50°C), ideal for indoor environments.
- Storage Temperature: Withstands -40°F to 150°F (-40°C to 65.5°C), ensuring durability when not in use.
- Humidity: Operates in 5% to 95% relative humidity (non-condensing), adaptable to varying conditions.
- Dimensions: Measures 5.94 in. (151 mm) wide, 4.13 in. (105 mm) high, and 2.26 in. (57.4 mm) deep, compact for panel mounting.
- Weight: Weighs 0.9 lb (0.41 kg), lightweight for easy installation.
- Mounting: Designed for DIN rail or panel mounting, with a minimum clearance of 2 in. (50.8 mm) on all sides.
- Terminal Blocks: Uses removable terminal blocks accepting 14-22 AWG wire, simplifying connections.
- Real-Time Clock: Maintains accuracy with a 100-hour backup at 77°F (25°C) using a super-capacitor.
- Protection: Rated IP20
