Bacnet and modbus I/O modules

The T3 general purpose modules add input/output expansion space for building automation systems. Integrators regularly tell us they are winning more projects because of the excellent price point and features of these devices.

 

Product Highlights:

  • Surge-protected Universal Inputs with 12-bit resolution
  • UL listed ABS enclosure with rubberized texture creates a high end feel
  • UL listed relays, terminal blocks and PCBs
  • Ethernet Protocols: Bacnet IP and Modbut IP
  • RS485 protocols: Bacnet over MSTP and Modbus RTU
  • Software configure the I/O ranges with the free T3000 software or by writing to the registers with your own software
  • Each output has a hand-off-auto switch for easy overrides
  • Plenty of LEDs show the status of each i/o and all communications ports
  • DIN rail mount or use the screw tabs for direct mounting onto a back panel
  • Each I/O as well as the RS485 connections a separate screw terminal
  • Source code for the modules is available
  • The RS485 port has separate upstream and a downstream connectors to make troubleshooting easier

Description

The BACnet and Modbus I/O modules work well with Siemens, Reliable, Delta, KMD, Tridium, etc.T3E-22i and T3E-886 support both BACnet and Modbus over both RS485 and the ethernet ports. All settings are available as BACnet objects and Modbus registers.

The T3E-32i has 32 inputs and the T3E-22i has 22 inputs. Both models share the same specifications except for the number of inputs. The wiring is slightly different though, each input on the T3E-22i has two terminals: one for the input signal and another for the ground.

The T3E-32i has ten more inputs than the T3E-22i. It requires the ground terminal to be shared among multiple inputs.
