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.
The T3 Series Modules are general purpose input/output modules for building integrators. Available in several input/output configurations, the T3 Series Module provides convenient termination for field devices and interfacing to HVAC, lighting, temperature sensors, and other typical building automation applications. Each of the Universal inputs can be configured, via jumper, for either 0-5V or 0-20mA signals. The outputs are available in dry contacts 1amp/output, 0-10V analog, and PNP sinking. The modules are slave devices that can be easily controlled via the RS485 serial interface using the industry standard Modbus RTU Protocol.
