Product Description

Description: 
The t3 general purpose modules add input/output expansion space for building automation systems. integrators regularly tell us they are winning more projects becuase of the excellent price point and features of these devices. works well with seimens, reliable, delta, kmd, tridium, etc. 

T3-22I and t3-8o support both bacnet and modbus over both RS485 and the ethernet ports. all settings are available as bacnet objects and modbus registers.

Featuers: 

-surge-protected universal inputs with 12-bit resolution
-UL listed ABS enclosure with rubberized texture creates a high end feel. 
-the RS485 port has separate upstream and a downstream connectors to make troubleshooting easier. 
-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 troubleshooting and overrides. 

each I/o as well as the RS485 connections have a separate screw terminal, there's no need to gang two wires under one terminal for any of the terminations. 
-baudrates: 9600, 19200, 38400, 57600 and 115200BPS
-the t3 modules support bacnet over mstp and TCP/IP as well as modbus. 

Source code for the modules is available with your first purchase.

The t3-22I has 22 inputs, 2 RS485 terminals that share the same serial port, and 1 ethernet port. 

The t3-8o has 8 inputs, 8 outputs, 6 relays, 2 RS485 terminals that share the same serial port, and 1
ethernet port. 

Standard operation
input:
each input of a t3 module can be configured in 1 of 5 ways: 
0-5V
0-10V
4-20mA
10k type2 ntc
pulse counter
the value of each input is stored as a 12-bit number in the respective modbus register, for register and pulse input info please go to temcocontrols.COM website.

The maximum values for the 5V, 10V, 20mA is 4095, and pulse counter con figurations would produce a reading of 65536*65536=4294967296. each input has a corresponding LED which will light up if the value of the input is greater than 2048.


baudrate

t3-22I and t3-8o have adjustable baudrates that are set by register 15. the options include: 
value 0 will set the baudrate to 9600BPS
value 1 will set the baudrate to 19200BPS
value 2 will set the baudrate to 38400BPS
value 3 will set the baudrate to 57600BPS
value 4 will set the baudrate to 115200BPS
