The T3 series Bacnet programmable controller is a low cost performer with big system features. There are three versions with various I/O configurations and can be expanded with external i/o modules to form a complete building automation solution.
Duct temperature and humidity sensor / transmitter is applicable to all kinds of building automation, environment monitoring, HVAC systems. Product appearance is simple, direct connection terminals, convenient installation.Products use high performance embedded microprocessor, and high-precision sensors to meet all kinds …
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.
GK-7000 is a high performance embedded industrial computer with a capacitive touch screen user interface. The CPU is the Samsung S3C2440 which is based on an Arm9 core. It’s Linux 2.6.32 operating system. This computer offers a full list of technical specs at low power consumption and high reliability.
The OR-485 is an externally powered isolated converter/repeater with diagnostic LEDs.There are two input ports which can be designated, via jumper, as either RS232( for connection to a PC as a converter), or RS485 (for bus repeater mode). The isolated, half-duplex RS485 output port has two separate connectors to make dividing the network simple for troubleshooting. The diagnostic LEDs show common wiring mistakes such as short or open circuits. All protocols (Bacnet, Modbus, generic RS485 protocols, etc.) are supported. Some of the diagnostics, such as “bad CRC” and “Modbus” error reporting, however, are available only with Modbus at 19.2k or 9600 baud.
Module T3-485-1 can change TXD and RXS signal data of RS232 serial interface to twisted pair RS485. The unti-scavenges power is from the RS232 lines so there is no need for an external power source. Pin3 (TXD) , Pin7 (RTS) and Pin4 (DTR) provide enough power. Auto flow control means you don’t have to install special drivers. The cable provided connects to most Temco controls equipment directly. It can be easily cut and customized in the field or write to us and we’ll make a custom version for you at no extra charge.
