ZIGBEE CONTROL UNIT C4

SR-ZG2833PAC-C4

Product description

Zigbee Control Unit for up to four inputs with integrated Zigbee Router functionality
Four configurable 230V~ inputs, can be individually set-up as on/off, level control, window covering controller and
scene selector switches use with momentary or stationary switches
Reliable, unattended, maintenance-free operation; designed for in-wall flush-mounting
Made in China using high-quality, enduring parts for many years of life expectancy
Low power dissipation: 0.3W
Supports all channels in the 2.4 GHz band, i.e. channels 11-26 as per IEEE 802.15.4
Primary channel set = (11, 15, 20, 25 )
Secondary channel set = (12, 13, 14, 16, 17, 18, 19, 21, 22, 23, 24, 26 ]
Works under the Zigbee 3.0 common profile (former Zigbee Home Automation Profile ID)
Supports joining centralized and distributed security networks as router
Supports forming simple centralized security networks as Coordinator and Trust Center
Supports forming distributed security networks as router
Three pre-configured Trust Center Link-Keys for joining:
Global Default Trust Center Link-Key
Global Distributed Security Link-Key
Device-individual link-key derived from installation code
Includes 128-bit installation code for secure joining (text and QR barcode)
Extended neighbor table with up to 64 entries for routers and end-devices more than 2 the capacity required by the
standard (25)
Extended buffering for sleeping end-devices with up to 10 buffers 10 times the capacity required by the standard (1)
Extended APS duplicate rejection table with up to 30 sIots – 30 times the capacity required by the standard (1)
Extensive transmit and receive queues for optimum through-put and minimum packet drop rate
Reliable and scalable network-wide broadcasts featuring passive acknowledgments
Reliable packet forwarding with automatic network-level retries
Very sophisticated routing algorithm for reliable ad hoc routing avoids routing loops even in case of concurrent route
requests with overlapping source/destination
Firmware upgradable over-the-air during normal operation using Zigbee OTA Upgrade Cluster
Man-Machine-Interface: A push-button and a LED for network steering, factory reset etc.
OEM and customized versions available upon request

The ZIGBEE CONTROL UNIT C4 is a Zigbee 3.0 control device with integrated router functionality, designed for in-wall flush mounting and supporting up to four individually configurable 230V~ inputs for on/off switching, level control, window covering control, or scene selection using momentary or stationary switches. It supports both centralized and distributed security networks with advanced security features including multiple Trust Center Link-Keys and a 128-bit installation code for secure joining, along with extended capacity for routing, buffering, and duplicate rejection far beyond standard requirements. Operating across all Zigbee 2.4 GHz channels, it enables reliable packet forwarding, robust ad hoc routing, and OTA firmware upgrades, with a simple push-button and LED interface for local control and configuration.
