GC8846P

Description

GC8846P is a POWERFULL BACnet B-BC class standalone controller with router function but can also be a communication bridge between workstation and field controllers. Onboard communications consist of 1 x 10/100M Ethernet port, 1 x MSTP port (32 Devices), 1 x selectable Modbus RTU or MSnet Port (direct connect HMI screens) and 1 x EIM Expansion port (24 Devices).

It is equipped with 8BI/8UI/4BO/6AO on-board as well as being able to expand to 24 more EIM expansion modules making it a very versatile product that can be used for small to large point projects. There are many features such as 365 day Time Clock/Holidays etc, 100 Trend Logs, 100 schedules, 1000 Av&Bv points. Bo’s have A/O/M switch & Ao’s have A/M switch with adjustable pot to regulate 0-10vdc output which is very useful for commissioning/Testing.

Features

• BACnet Building Controller (B-BC) class listed device.
• Compliance BACnet Ethernet, BACnet/IP, and MS/TP communication standards as a router. 
• An Ethernet communication interface can be either BACnet Ethernet (ISO-8802-2) or the BACnet/IP communication protocol.
• An MS/TP(Master-Slave/ Token-Passing) port, Peer to Peer communication. Can read (DS-RP-A/DS-RPM-A) and write (DS-WP-A) BACnet objects.
• A RS-232 port for setting up initial device parameters using a null modem or AD-linker cable and a Terminal program such as HyperTerminal.
• Di’s have 1000VDC optical isolate protection and status indicator LED’s.
• 16 bit Ui’s, jumper selectable 3K or 10KΩ NTC thermistor, 4~20mA, or 0~10VDC, dry contact input signals.
• Triac Do’s have 1000VDC optical isolate protection and status indicator LED’s. Each Do have a Manual OFF-ON/Auto switch with internal override Flag status that can be used to trigger events or Alarms.
• Ao’s are 12 bit, 0~10VDC output signals. Each Ao have an Auto-Man switch with adjustable 0-10vdc pot and also an internal override Flag status that can be used to trigger events or Alarms.
• On-line firmware updates and DDC program editing, real-time program debugging, significantly reducing the programming and editing time.
• Real-time clock, Calendars, Schedules, Notification Class, Event Enrollments, Trend-logs standard BACnet objects. Schedules and event enrollments support external object access function.
• Onboard 1,000 Binary Value with 16 Priority Array (BV) and 1,000 Analog Value (AV) points,
• Monitor and program over the internet.
