The S300-DIN-RDR8S module provides interface control for access and security devices associated with up to eight doors. The I32O16 module supports 32 inputs, 16 relay outputs, and 16 open collector outputs. Both RDR8S and I32O16 use standard RS-485 communications and can interface with the following controllers:
• CK721-A version 3.0 and higher
The RDR8S provides the ability to configure supervised 4-state inputs and unsupervised 2-state inputs. A total of 32 inputs can be configured as supervised 4-state inputs (normally open or normally closed), or 2-state inputs. Any points not used for the door can be configured as general purpose I/O points, possibly eliminating the need to purchase additional I/O modules for certain installations.
The RDR8S provides power for the card reader hardware. It does not provide power for door locking hardware.
•Wide range nominal voltage for power source – From +12 to 24VDC
•Support for RS-485 bus communications at 9600 or 19200
– Auto baud rate detection (9600/19200 baud)
•Easy installation – Modules can be mounted on a flat surface, DIN rail, or in a Johnson Controls’ approved enclosure.
•Expandable modular design – RDR8S and I32O16 modules can be connected together via RS-485.
•Eight-door access control input/output interface – See RDR8S or I32O16 Sample Configuration
•Input Point/Output Point Disassociation (RDR8S only) – Reader terminal input/output (I/O) points can be re-assigned from reader-specific functions to general purpose I/O points.
