Siemens BACnet Programmable TEC
Extended I/O Controller
The Siemens Extended I/O Controller is designed to
allow point expansion for other Siemens controllers
and reside on any BACnet control system.
Features
 Communicates using BACnet MS/TP protocol for
open communications on BACnet MS/TP
networks.
 BTL listed as a B-ASC device.
 Programmable using PPCL.
 Plenum rated controller.
 Setpoints and control parameters assigned and
changed locally or remotely.
 Setpoints and control parameters stored in
Electrically Erasable Programmable Read Only
Memory (EEPROM)—no battery backup required.
 Returns from power failure without operator
intervention.
 No calibration required, thereby reducing
maintenance costs.
 PID control of HVAC systems to minimize offset
and maintain tighter setpoint control.
 Unique control algorithms for specific applications.
 Separate air volume setpoints for occupied and
unoccupied modes (CV Applications only).
 Uses proven DDC architecture.
Applications
 Extended I/O — Application 6596
Control algorithms are preprogrammed in the
standard application(s) residing in the controller. The
controller is designed for operation and modification
without vendor assistance.
If required, new custom code using our PPCL
programming language can be added to replace or
supplement the standard application(s) residing in the
controller. This provides the flexibility to meet many
job specifications with the assurance of having proven
and tested standard applications to rely upon.
Hardware
Controller Board
The Siemens Extended I/O Controller consists of an
electronic controller assembly.
This controller provides all wiring terminations for
system and local communication and power. The
cable from the room sensor (purchased separately)
connects to an RJ-11 jack on the controller. All other
connections are removable terminal blocks. The
controller assembly is mounted on a plastic track that
mounts directly on the terminal box. An optional
